Improve beans fertilization efficiency and promote high yield
Beans like hi warm, intolerant of frost, suitable for the growth temperature of 20 to 25, beans need fertilizer law, the seedling period requires less fat, but very sensitive, branching period, plot selection, to choose fertile, loose loam or Sandy soil is suitable, and with leguminous crops.
The bean basal fat is sufficient to promote the growth of roots and the activity of rhizobial bacteria, forming more nodules. Basal fertilizer generally applies 2000-3000 kg of organic fertilizer per mu, 25-30 kg of superphosphate and 50 kg of plant ash. Before the flowering and scabbing of the bean, the requirement of water and fertilizer is not high, and the management is mainly controlled. The basal fertilizer is adequate, and it is generally no longer top-dressing. When the weather is dry, it can be properly watered.
If there is too much water and fertilizer, the stems and leaves are too long, and the application of Huawang No. 3 on the sticky branches will replace the hormone control, which will enable the fruit trees to set up more fruit, expand faster and neatly capped, optimize fiber quality, increase the proportion, and increase production and income.
When the plant's first inflorescence pods are sitting, the following inflorescences appear to be combined with topdressing and watered once, and nitrogen, phosphorus, and potassium fertilizers are applied in 10 to 15 kg per mu, and irrigation is performed in 20 to 30 cubic meters. After scabs, keep the soil moist and apply fertilizer 1 time every 1 to 2 weeks to keep the plants robust and flowering.
Into the pod harvesting period, the need for more water and fertilizer, can be followed by 1 irrigation fertilizer, 10 kg per mu urea, superphosphate 20 ~ 25 kg, 5 kg of potassium sulfate or 40 kg of plant ash, irrigation 20 ~ 30 per mu cubic meter. If the supply of water and fertilizers is insufficient, plant growth declines, and flowering and falling will occur.
