Cotton: Proper management can reduce boll shedding
There are three main reasons for cotton bud and boll shedding: one is physiological shedding, which is also the main reason for shedding. Because of the mutual influence of meteorological conditions and nutritional conditions, it leads to metabolic imbalance in cotton plants and insufficient nutrition, resulting in physiological shedding of buds and bolls; The other is that adverse weather conditions aggravate the harm of diseases and insect pests. Cotton aphids, red spiders and other pests bite leaves, reducing the photosynthetic capacity of leaves, resulting in malnutrition of buds and bolls, increasing shedding, excessive spraying, high concentration of liquid medicine, short spraying time interval and other phytotoxicity, which will also increase.

Emergency measures for Cotton Bud and Boll shedding
When cotton grows in high temperature and rainy climate, a large number of buds and bolls will fall off, resulting in plant height, size and emptiness, resulting in a large reduction in yield. According to the causes of different shedding, corresponding emergency remedial measures can be taken. For cotton fields that have been dry for a long time without rain and can not be watered, the leaves of cotton plants are thin and small, the leaves are light green and yellow, the chaff of buds is small, heavy rain falls heavily, light rain falls less, and no rain falls gradually. Remedial measures: 200 grams of multi-element boron fertilizer per mu plus 20 ml of Fengchengning, evenly sprayed with 50 to 60 kg of water, interval

Scientific fertilization can reduce cotton bud and boll shedding.
The vegetative growth (root, stem, leaf growth) and reproductive growth (bud, boll, boll growth) of cotton are not coordinated, resulting in the imbalance of the supply, transport and distribution of photosynthates in cotton plants, which is an important reason for the shedding of cotton buds and bolls. Through comprehensive measures centered on fertilization, controlling cotton growth is an important means to reduce cotton bud and boll shedding. Practice has proved that controlling the stem and leaf growth of cotton in the early stage, setting up a high-yield shelf in the middle stage to make it grow steadily and preventing premature senescence in the later stage is an effective way to reduce the shedding of buds and bolls in the middle and lower parts. Therefore, in addition to reasonable close planting, strengthen the water

How to prevent the shedding of soybean flowers and pods when planting soybean
First, topdressing because of the land and the seedlings. The field in which the plant can not be closed in time due to lack of fertilizer at flowering stage can be fertilized again at the early flowering stage. Generally, 5 kg urea or 10 kg ammonium sulfate per mu can reduce the shedding of flowers and pods. Second, spraying fertilizer outside the root. Usually use urine per mu during the flowering and pod period.

There are many measures to prevent soybean from falling flowers and pods.
The drop of flowers and pods is an important factor affecting the yield of soybean. Under general cultivation conditions, the shedding number of flowers and pods can account for more than 50% of the total number of flowers, and seriously up to 70%. The shedding of soybean flowers and pods is mainly due to the internal physiological imbalance of the plant and poor external environmental conditions. According to our practical experience, the following measures can be taken to prevent the shedding of soybean flowers and pods: 1. Increase the application of phosphorus and potassium fertilizer, appropriate topdressing nitrogen fertilizer and micro-fertilizer. The application of phosphorus and potassium fertilizer to soybean can reduce the shedding of flowers and pods and promote the fullness of grains. Therefore, on the basis of applying sufficient base fertilizer, every 66 of the time of sowing

Generally, 5 kg urea or 10 kg ammonium sulfate per mu can reduce the shedding of flowers and pods. Second, spraying fertilizer outside the root. In flowering and pod stage, 0.5 kg urea, 1.5 kg superphosphate, 0.25 kg potassium sulfate, 25 g borax and 50 kg water are used to spray the leachate per mu, which is suitable for spraying on cloudy days or after 4: 00 p. M., which is beneficial to flower protection, pod and grain increase.
