Introduction to spring grass cultivation management methods :
The spring grassland produces South Africa, which is cool, humid and sunny. It is afraid of damp heat, is resistant to half yin, is also resistant to drought, and has certain cold resistance. It has the habit of high temperature dormancy in summer and cold season in autumn to spring.
Temperature: Spring grass is cool and hot, the main growth period is from September to April of the next year, and the temperature should be kept at 10 °C to 20 °C in winter. In this environment, the plant can continue to grow and can manage normal fertilizer and water. If you control the watering and make the plants dormant, it can safely overwinter at not less than 5 °C. With the increase of temperature in the middle and late May, the leaves on the ground gradually withered, the plants enter a dormant state, the dried leaves can be removed, the bulbs are left in the original pots, and the flower pots should be placed in a dry, ventilated, non-storage area. By the end of August and the beginning of September, as the weather turns cold, new shoots will grow out of the bulbs and normal management can be resumed.
Illumination: Spring grass is light, and sufficient light should be given during the growing season. If the light is insufficient, the blade will be weak and the degree of curling will be poor. It is difficult to highlight the unique charm of the spring grass. The leaves growing in the sunny place are low and thick, twisted and twisted, and have a high ornamental value. However, after April, the sunshade net should be used to avoid sun exposure and prevent the tip of the leaves from drying out.
Water and fertilizer: The spring grass prefers a humid environment. In the growing season, the soil should be kept moist without water. If the plant is not dead for a long time, the plant will not die, but the growth will be stagnant, the leaves will be yellow and even withered; and the basin will have long-term water accumulation. Will cause the bulb to rot. Water can often be sprayed on the plants to increase the humidity of the air and prevent the tops of the leaves from drying out. In order to avoid flooding in the rainy season in summer, you can put the flower pot on the shelf or on a table with a certain height, and pay attention to controlling the watering to prevent the bulb from decaying due to the accumulation of water, but you can't let the potting soil completely dry out to avoid the bulb. Dry. From October of each year to April of the next year, the plant grows vigorously, and a decomposing thin liquid fertilizer or compound fertilizer is applied once a month to provide sufficient nutrients to make the plants grow vigorously. After the spring flower buds are taken out, 0.5% phosphoric acid is sprayed. Potassium dihydrogen solution 2 to 3 times to promote flowering.
Pollination: After spring flowering, different plants should be selected for artificial pollination, so that the results of the plants, after the seeds are mature, pay attention to harvest, do not let them scatter; if you do not leave seeds, you should cut off the remaining peduncle in time to avoid excessive consumption. Nutrients.
Change basin: Spring grass is generally changed at the end of August every year. The potting soil is fertile and loose. It contains rich humus and has good drainage and permeability. It can be mixed with turf or turf soil, 3 parts of vermiculite or sand. And a small amount of bone powder is added. When changing the pot, cut off the decaying root system. When planting, the bulb will be exposed to the soil surface for about 1/3. After planting, the water will be drenched and placed in a well-lit place. After careful attention, keep the soil moist. Soon, new leaves will grow from the top of the bulb. .
