Recently, Yangchun City, a Huang surnamed fruit farmers for his 200 acres of longan guilty: nowadays, is the key period for longan to apply quick-acting fertilizer to attack the autumn shoot. However, more than 100 yuan / pack of urea made him a dilemma. If you go on high cost, but you don’t know what will happen next year? Without fertilization, the fruit tree harvest is certainly hopeless.
Of course, it is not just the fruit grower in Yangchun, but the millions of farmers in the province. Nowadays, it is the time when the agricultural fertilizer in summer and autumn in our province is relatively large, and the fertilizer (mainly urea), which has remained high for more than two months, has become the pain of farmers in our province. How can we reduce the cost of fertilizer and increase the utilization of fertilizer? Many soil and fertilizer experts in the Provincial Fertilizer Association and South China Agricultural University, which were interviewed by this reporter, suggested changing the habit of partial application and excessive application of nitrogen fertilizer, and rational application of organic fertilizer is a good way to solve the problem.
Partial application of nitrogen fertilizer
Increased use of fertilizer
Professor of Soil and Fertilizer Experts from South China Agricultural University revealed that developed countries attach importance to scientific fertilization, and the nitrogen utilization rate is 40% or even 50%. However, due to the widespread use of farmers in China and the application of nitrogen fertilizer, the nitrogen fertilizer efficiency has generally declined. The utilization rate is low, only about 30%.
This evil has been exposed in many areas. According to many farmers, because of little or no organic fertilizer, the “appetite†of cultivated land is getting bigger and bigger: 100 kg in the first year, 110 kg in the second year, and 130 kg in the third year. In order to ensure equal production, the cost of 30 kg of fertilizer is increased in vain!
Soil and fertilizer experts explained that the main reason for this phenomenon is that the application of chemical fertilizers has led to a continuous decline in the effective amount of trace elements in the soil. Because of the normal growth of crops, in addition to the absorption of nitrogen, phosphorus, potassium nutrients, but also absorb calcium, magnesium, sulfur, iron, manganese, boron, zinc and other trace elements, if an element can not be satisfied, it will affect It grows. For example, in our province, we have planted a large area of ​​litchi, longan, citrus, etc. After several years of continuous fruit harvesting, many orchards have obvious symptoms of deficiency. Fruit farmers mistakenly believe that they are short of fertilizer, and then increase the application rate, so that the cost is increasing. And the effect is not ideal.
Nowadays, the price of nitrogen fertilizer has soared, and the compound fertilizer has risen. This waste has further increased the cost of fertilization, which is undoubtedly worse for farmers. Professor Yu believes that under the influence of the current dual factors, farmers must change the habit of re-application and partial application of nitrogen fertilizer, promote balanced fertilization, and apply organic fertilizer for rational crop matching. For example, if you buy half of the fertilizer to buy organic fertilizer or organic compound fertilizer, the application effect is much better than the full application of chemical fertilizer.
Commercial organic fertilizer
Adapt to the needs of the development of the situation
The senior agronomist of the Provincial Fertilizer Association, Zeng Sijian, believes that the application of chemical fertilizers is the need for agricultural development and agricultural production. When agriculture enters a new stage of development, it must adhere to the principle of “combination of organic and inorganic, combining land and raising landâ€. Appropriate use of organic fertilizer can change the single phenomenon of soil microbes, thus achieving twice the result with half the effort.
Nowadays, with the development of the economy, farmers are paying more and more attention to production efficiency, economic benefits and the convenience and sanitation of fertilization. The traditional farmyard manure is hand-made, self-contained, more laborious, labor-intensive, and more odorous. The peasants circulate the "white without black, dry without wet", "take a good burden." "The saying is to reflect the modern farmers' demand for organic fertilizer.
In addition, the rapid development of China's green food and organic agriculture in recent years has played a role in fueling the development of organic fertilizer. Therefore, the appearance of organic fertilizer has followed the needs of the development of the situation. According to industry insiders, in the next few years, the proportion of organic fertilizer used in our province will be higher and higher.
Organic compound fertilizer
Easy to apply
It is understood that in recent years, the number of organic fertilizer manufacturers in our province has been increasing. Organic fertilizers and organic compound fertilizer products have emerged in an endless stream. Farmers can buy them directly from fertilizer stores, and the price of these fertilizers is about half of that of fertilizers. It is said that the yield of high-quality commercial organic fertilizer 200-300 kg, the effect can be equivalent to 3000-5000 kg of farmyard manure, which is economical and convenient to apply.
“It’s not chemical fertilizer, it’s better than chemical fertilizer; it’s not peanut bran, it’s better than peanut bran.†A nuclear-free yellow-skinned grower in Yunfu City is deeply touched. At the beginning of this year, he bought 2 tons of organic compound fertilizer on the yellow-skin tree with a try mentality, and compared it with the yellow-skin tree that applied farmyard manure. When harvested in July, it was found that the effect of applying organic compound fertilizer was significantly better than that of farmyard manure: the yellow-skinned fruit was full, the size was uniform, and the meat was thick and sweet, which was favored by fruit sellers.
The difference in the effect of the two fertilizers made the fruit grower puzzled. Associate Professor Xie Lichang, a professor of soil and fertilizer at South China Agricultural University, said that the characteristics of inorganic fertilizers are fast, the characteristics of organic fertilizers are stable, and the combination of organic and inorganic components can achieve the advantages of fast and stable fertilizer, while adding high quality and supplementing organic matter. . According to Professor Liao Zongwen, a soil and fertilizer expert at South China Agricultural University, the biggest role of organic and inorganic components in organic compound fertilizer is to have the characteristics of simultaneous and co-empty, achieving the balance of organic and inorganic, so that the fertilizer can avoid the shortcomings of chemical fertilizers.
Liangtian Luxing Letian
Three major manufacturers are rich in products
As the first organic and inorganic compound fertilizer manufacturer in the country, Guangzhou Liangtian Fertilizer Co., Ltd., its Kangbao brand six series of organic and inorganic compound fertilizer products sell well all over the country. At the same time, the company's pioneering “development of multi-functional organic-inorganic compound fertilizer (controlled release fertilizer) using industrial and agricultural waste†plays an important role in recycling waste resources, maintaining ecological balance and protecting the environment.
Following the successful introduction of organic fertilizers and organic-inorganic compound fertilizers, Yunfu Luxing Compound Fertilizer Co., Ltd. recently introduced a liquid organic compound fertilizer that can be applied and sprayed on the surface. It can be said that it is organic fertilizer and organic compound fertilizer. Upgrade. Last year, Yungui Shajiao grower Chen Guinian used this fertilizer to enjoy a bumper harvest and improved quality. His experience was broadcast on CCTV Spark Technology, and the audience reflected strongly.
The up-and-coming Guangzhou Letian Eco-friendly Organic Fertilizer Plant, a high-tech bioactive organic fertilizer produced with the core technology of “nitrogen-fixing bacteria, phosphate-dissolving bacteria and potassium-dissolving bacteriaâ€, has been rapidly promoted in Guangzhou and surrounding areas in less than a year. Application, favored by farmers who grow leafy vegetables, melon beans, potatoes, etc. In particular, it is applied to sweet corn, the stem is thick, the leaves are thick, the disease resistance is enhanced, and the yield and quality are obviously improved.
White organic fertilizer
Mostly inferior goods
At present, as domestic organic fertilizer is in the initial stage of development, the quality of the products is mixed, and farmers will buy some inferior commercial organic fertilizer from time to time, the effect is not obvious. To this end, industry insiders familiar with the market reminded that if you do not understand the true and false consumers, you can look at the appearance of fertilizers when buying, because the color of organic fertilizer and organic compound fertilizer is mostly black. If it is white, most of them have quality. The problem, you need to be careful not to be deceived.
In addition, the organic fertilizer efficiency of different raw materials is also different. According to the relevant experts of the Provincial Soil and Fertilizer Station, according to the current commercial organic fertilizer standard, the required organic matter can reach 30%, and different manufacturers may use different raw materials, such as chicken manure, pig manure, peat soil, bagasse, furfural residue, wood chips. , straw and other production of different organic fertilizers. However, according to relevant sources, although the organic matter content is 30%, it is much better to use chicken manure as raw material than wood chips. It is understood that at present, the organic fertilizer produced by chicken manure in our province mainly includes Yunfu Luxing Organic Fertilizer, Guangzhou Letian Organic Fertilizer, Yuexing Organic Fertilizer, Delong Organic Fertilizer, Guangzhou Likang Organic Fertilizer and Kangbao Organic Fertilizer. and many more.
According to reports, some manufacturers who illegally produce organic fertilizer often use fake raw materials to mark chicken manure, peanut bran and other raw materials on the packaging, but the price is lower than similar high-quality products. Farmers should not buy cheaply because peanut bran is used. Tons of more than 2,000 yuan, using it as raw material to produce organic fertilizer, the cost is obvious.
