Today (21st) is a small full-fledged festival. From today to the Mang's solar terms, the whole country gradually entered the summer, the temperature difference between the north and the south further narrowed, the precipitation increased further, and it was prone to severe weather such as heavy rain, thunderstorms and hail. Farming activities are also about to enter the busy season, and the summer harvest is mature or near maturity; spring-sown crops are growing vigorously; late autumn crops are planted soon. Therefore, all agricultural production units, business households, and individuals must make overall considerations, make arrangements, and take care of the points.
1. The spring sowing work in the northern region has basically ended. The local area management of spring-sown crops should be done well. The areas where rainfall has recently occurred should seize the favorable opportunity after the rain, check the seedlings in time, replant seeds, and strive for Miaoquan and Miaozhuang; Grasp the opportunity to arbitrarily plant corn, cotton, peanuts, etc. in the wheat field; spray a new high-fat film 500 times liquid in time to prevent the damage caused by high wind and strong cooling weather on spring seedlings.
2. The northern winter wheat enters the key stage of grain formation, milk ripening and other production. It should be poured with wheat yellow water to prevent dry hot air, prevent root and leaf premature aging, and spray a strong ear, to promote full grain filling of winter wheat and increase grain weight; The areas with deviations should be irrigated at the right time, and 600 times of new high-fat film should be sprayed to protect against the dangers caused by high temperature, drought and “dry hot wind†weather. For areas where heavy rain or strong winds may occur, do not water before the weather process. Reduce wheat lodging. The southern summer grain and oil crop production areas should grasp the fine weather, timely harvest the mature wheat and rapeseed, avoid the loss caused by adverse weather, and actively prepare for the summer harvest, summer sowing and summer tube. In the south and south of the Yangtze River, attention should be paid to shallow water irrigation and timely fertilization after early rice transplanting, to promote early fast-growing and multi-split of early rice; to drain the field in time for the seedlings, control the ineffective tillering, and pay attention to the monitoring of rice field pests and diseases. And prevention matters.
3. Strict organization, prevention of scale, elimination of pests and diseases, and enhancement of crop management. It is necessary to spray targeted pesticides to control high-risk pests and diseases such as wheat powdery mildew, rust and aphids in a timely manner, and strive for a good harvest in summer. It is necessary to strengthen field management measures such as pest control, weeding, and fertilizer management for cotton, corn, and various autumn crops to ensure that the seedlings are complete and robust, and lay a good foundation for the harvest. The production of various types of forest fruit, melon, seasonal vegetables, medicinal materials, tobacco and other crops has reached a strong growth or process. At this stage, high temperature and windy, high humidity and dryness are impermanent, suitable for the spread of various pests and diseases, and effective prevention and control must be carried out. It is necessary to spray a targeted agent such as 50% carbendazim (or 70% methyl thiophanate, 40% anthrax fumei) + new high fat film 800 times liquid to prevent fruit diseases such as anthracnose, ring disease, brown spot, Scab, fruit rot, downy mildew, etc. Scientifically and rationally use high-efficiency and low-toxic targeted agents + new high-lipid membrane to timely control high-risk insect pests such as heartworm, aphids, dead leaf moth, jujube step, whitefly, pear stem bee, etc., to ensure that pests are effective before they fail. Prevention and treatment.
4. Flower production management is at the time. After the Xiaomang, the temperature rises, the rainfall increases, the flowers grow fast, and pests and diseases are prone to occur. Strengthening management is crucial.
First, timely control of pests and diseases, can choose 1% equivalent Bordeaux night, tree general, 70% methyl thiophanate or 50% carbendazim WP 1000 times + new high fat film 800 times liquid to control peony leaf spot Powdery mildew and brown spot disease of flowers such as disease, rose, rose, etc.; 40% liquid milk solution 1000 times liquid (or 25% deltamethrin 3000 times liquid) + new high fat film 800 times liquid can be used for all kinds of flower aphids Effective control of pests such as spider mites.
The second is to do a good job in field management, and combine cultivating as soon as possible to clear the weeds in the field, keep the soil loose and breathable and the circulation of air between the lines, avoid nutrient dissipation and reduce the occurrence of pests and diseases.
The third is to pay attention to fertilizer and water regulation. The demand for water in flowers is increased, and watering is timely. For flowers that like acidic soil, such as camellia and rhododendron, an appropriate amount of ferrous sulfate can be added to the water. Pay attention to prevent water accumulation and drain in time after rain. Strengthen fertilization management. The peony is applied to the bud fertilizer to promote the vegetative growth of the peony. The compound fertilizer mainly based on nitrogen fertilizer should be applied after the flowering of the camellia and rhododendron; the stalked potato water should be applied to the foliage plants such as green radish and fern; For the flowers that are blooming in the rose, pomegranate, etc., the compound fertilizer mainly based on phosphorus and potassium fertilizer should be applied, and the flower buds should be sprayed in the flower bud differentiation stage to promote the formation of flower buds and promote flowering.
The fourth is plastic trimming. For the flower growing period, the cuckoo cuts the dense branches, the delicate branches and the diseased branches; the rose cuts off the residual branches; the peony cuts off the residual flowers, reduces the nutrient loss, and avoids the occurrence of pests and diseases.
The fifth is to adopt various effective methods such as cutting propagation, ramets breeding, and layering and other vegetative propagation means to breed at the right time. Regardless of the breeding method, the new high-fat film 300 times liquid immersion treatment should be carried out on the base of the seed (branche) cuttings. It can prevent the infection of germs, can rid the underground pests, isolate the virus infection, and improve the survival rate of reproduction.
