The root system of green beans is well developed and suitable for growing in loose, fertile, well-drained soil. After the seedlings are unearthed, the root system absorbs various nutrients from the soil. There is nodules on the roots of the beans, and nitrogen can also be fixed from the air for plant growth. During the flowering and podling period, the storage of nutrients in stems and leaves reached a maximum value. Later, as the growth of N. sinensis grows, the nutrients in the stems and leaves will rapidly and continuously transfer to the tender larvae for the growth and development of the larvae. The plants grown in the green beans have a slower growth and a longer growth period. The absorption of nutrients from the soil is slower. The conversion of nutrients from the stems and leaves to the tender pods is also less, and the proportion of the roots is larger. According to the determination, the conversion rate of the green beans from stems and leaves to tender pods was: nitrogen 17%, phosphorus 20%, and potassium 31%. Therefore, the cultivation of green beans, in addition to the requirement of basal fertilizer, but also to stage fertilizer. Generally when the earthworms are planted, Mushi organic fertilizer is 4000-5000 kg, compound fertilizer is 50 kg, and appropriate amount of trace elements. In the seedling stage, the fertilizer may not be top-dressed. If the soil fertility is insufficient, the shoot-up seedling fertilizer may be appropriately chased to promote the normal growth of the seedlings. From the differentiation of flower buds to pods, top dressings can be made according to plant growth conditions. After the planting period, the stems began to grow vigorously, and the water was interposed to interpose the scaffolds. It was possible to use 1,000 kg of manure or organic manure, or 250 kg of bio-organic fertilizer, to promote the growth of stems and leaves and lateral branches and increase the number of flowers. , Make early knots. When the tender in the first inflorescence is seated, it can be used as a fertilizer, and 10-20 kg of Mushi compound fertilizer can be used to promote the growth and production of N. sinensis and increase the yield. In the late growth stage of the green beans, a large amount of nitrogen fertilizer can also be absorbed from the soil. Therefore, it is possible to carry out topdressing in the middle and late stages of harvesting of N. sinensis, and 10 to 20 kg of N fertilizer per mu to promote new lateral branch germination and flowering and scarring. The main vines lubricate flower buds, extend the time for harvesting tender pods, extend the supply, and increase yield, which has a significant effect. Dwarf green beans have a short growing period, and the harvest time of N. sinensis is relatively concentrated. When N. sinensis grows and grows, the transfer rate of nutrients transferred from stems and leaves is high, which is 24% for nitrogen, 11% for phosphorus, and 40% for potassium. In the early growth stage of dwarf green beans, the root system is still underdeveloped and the rhizobia are few. Under the condition of weak nitrogen absorption from the air, the supply of nitrogen fertilizer has a direct impact on the yield of green beans. Therefore, early recovery of nitrogen fertilizer, combined with watering, Mu can recover urea 20 ~ 40 kg and appropriate phosphorus, potassium fertilizer. If the basal fertilizer is sufficient, it may not be top-dressing. During the period of blooming and scabbing, the foliar spray of boron, molybdenum, and other trace fertilizers can increase the yield of green beans and improve product quality. Can be combined with pest control pesticide spray when spraying 0.2% of urea, 0.3% potassium dihydrogen phosphate, 0.08% ammonium molybdate and 0.08% boric acid, photosynthetic fertilizer, etc., with a significant increase in production. In the good breeding field of green beans, applying topdressing nitrogen fertilizer before flowering will help increase the seed yield and increase the protein content of the seeds, but not excessive nitrogen fertilizer application. Excess nitrogen fertilizer can cause plants to grow in length, causing a large number of falling flowers and falling seeds, reducing the yield and quality of seeds.
