Soybeans are Fallen and Fallen

Falling out of soybeans is the main factor affecting the increase of soybean yield. In terms of production, the falling rate of soybeans generally reaches 45%-70%. The most 3-5 days after flowering, the most falling flowers, 10-15 days after flowering. To increase the output of soybeans, it is necessary to make great efforts to prevent the falling of flowers.

Reasons for falling down

First, poor ventilation and light transmission; due to excessive planting density, poor planting techniques, leading to leggy, premature closure, and deterioration of light conditions in the lower part of the plant, resulting in leaf yellowing and shedding, less nutrient production and accumulation, resulting in shedding of flower buds; Unbalanced nutrient supply: Soybean bud stage is the period when nutrients are needed most. If the supply of nutrients is insufficient or imbalanced, it will cause a large number of flower buds to fall off. Third, the water supply is unreasonable: Soybeans have too little water during flowering, plant wilting, and soil nutrients. Absorption is reduced, imbalance of moisture and nutrients causes large amounts of flower buds to fall off. However, if the water content is too large, the ground temperature will decrease, the humidity will increase, the shade in the fields will be reduced, and the light and effects will be weakened. This will affect the synthesis and transportation of organic nutrients, and increase the shedding of flower buds. Fourth, pest and disease damage: destroy plant leaves, reduce light and intensity, and reduce The production and distribution of nutrients cause the calyx to fall off.

How to prevent flower buds from falling off

1. Proper and close planting The rational and close planting is to coordinate the contradiction between plant individuals and groups, make full use of the land and light energy, and obtain the central link of high yield of soybean. The rational dense planting can fully develop the population on the unit area, reach the highest degree of utilization of light energy and land utilization rate, and obtain high yield due to the increase of the number of grains, grains, and grain weight per unit area. The specific density should be based on the soil fertility, water conditions, species characteristics, generally 10,000 to 20,000 is appropriate.

2. Carefully chasing flowering and flowering stage requires a lot of nutrients. The base fertilizer and seed fertilizer used alone cannot meet the demand. Therefore, in the early flowering period, topdressing, especially barren, the development of thin seedlings, can not be timely closure of the field, topdressing urea 8-10 kg per acre. Can also be sprayed fertilizer, per acre spraying 0.3% potassium dihydrogen phosphate solution 60-70 kg, 50 kg of water can also be added 20-25 grams of ammonium molybdate, made into a solution, foliar spray, the effect is particularly significant.

3, timely irrigation and flowering, pod period, it is the most vigorous period of vegetative growth and reproductive growth, but also a critical period of water demand. Insufficient moisture will severely affect transpiration and photosynthesis and cause a large number of shedding. When the soybean grows slowly, the leaves are old and green, and the leaves of the noon are wilting, which is the performance of the soybean, and it should be timely watered. In the event of heavy rain, the accumulation of water in the field should be promptly eliminated to prevent floods.

4, to prevent leggy due to part of the plot of water and fertilizer conditions are good, combined with high density, branches and leaves long, field closed. In this regard, to be controlled, 15% paclobutrazol, 40 g of water, and 60 kg of water can be sprayed during flowering. It can also be sprayed with 0.2% of Chlormequat to suppress leggy.

5. Disease prevention and control pests Diseases of soybeans are mainly leaf spot disease. In the initial stage of disease and initial stage of scarring, use 70% thiophanate-methyl WP 800-1000 times, or 50% carbendazim WP 600- 800 times liquid spray control. The main insect pests are soybean borer, soybean meal, soybean aphid, etc. They can be sprayed with pesticides to reduce the occurrence of diseases and insects.
