When is the best time to harvest beans after pods are set? How to manage it after harvesting?

Guangxi Hepu County year-round high temperature and rain, sunny, temperature, light, water three elements to meet the pods growth needs, the pods planting as one of the main ways of farmers traditional income generation. In recent years, Hepu County, as an important hand in adjusting the agricultural structure and promoting farmers to increase income, increase the planting of soybean varieties, actively teach farmers modern soybean planting and management techniques, through the establishment of demonstration bases, demonstration pieces, demonstration furniture, to point to point large-scale production methods to improve soybean yield and quality. As a result of a series of scientific, planned policy measures, Hepu County's soybean angle economy gradually bigger and stronger. According to statistics, at present, Hepo County soybean pod planting area of nearly 0.93 million hm2, output of about 350,000 tons, output value of about 1.6 billion won, 11 out of 15 townships have been large-scale, specialized planting of soybean pods, employees amounted to 280,000 people, becoming China's largest soybean pods in the south of the largest planting base.

The individual development of soybean pods can be divided into four phases from the chronic species, seed germination, buds, canes and flowering pods until the pods mature or seed maturity. Hepu County combined with its own temperature, light, soil, water and other conditions, developed a pollution-free unit of high yield soybean cultivation technology. The specific methods are as follows. Open field soybeans are sown too late and encounter high temperatures during flowering, and lehua pods are serious. Or squatting or growing poorly in the seedling stage, poor flower bud differentiation, Lehua pods are easy to fall off. Plants can also drop pods during flowering if there is drought or too much humidity. Analysis results show that this plant's soybeans appear Lehua pods because, if not after the stunt squatting saplings, the plant will grow well into the flowering period, it will rain heavily, soil moisture is too high.

Pods should be well managed in the nursery to avoid the serious phenomenon of Lehua pods, in addition to open-air planting should pay special attention to the selection of the appropriate seeder. To avoid pods flowering pods in the high temperature period. When the phenomenon of Lehua pods occurs during the flowering period, the following measures can be taken immediately: if the pods are picked, the pods can be picked 2 ~ 3 times, put forward a fertilizer to ensure the supply of nutrients, 10 ~ 15 kg of nitrogen-phosphorus-potassium compound fertilizer per acre harvest, 5 ~ 10 kg of urea and about 15 kg of potassium sulfate.

Pods of pods for a long time long, the plant grows well, nutrition enough to pick many times. In the peak season of the first pod, if the plant's nutrition is concentrated on the pods, the plant's growth momentum will be weakened and the number of pods will decrease. Therefore, in order to have enough nutrients, fertilization is carried out a week before flowering, based on complex fertilizers and phosphorus-potassium fertilizers, and after the period of fertilization and fertilization will be carried out again, the exact amount of fertilizer used depends on the growth trend of the plant In addition, you can also use 5-25 ppm-acetic acid spray fire pots to prevent lehua pods, and to improve the rate of pods.
