Planting techniques of bean seedlings and vegetables

Soil: bean seedlings can choose well drained, loose and fertile soil. Rational fertilization: the base fertilizer was mixed with non-artificially treated farm fertilizer, urea, potassium sulfate and diammonium phosphate, and the topdressing was mainly nitrogen fertilizer. Sowing: sowing in spring and April. Late management: timely ploughing and weeding, reasonable watering according to weather changes. Control of diseases and insect pests: powdery mildew uses sulfur suspension, Fusarium wilt uses carbendazim to mix, rust can use rust wettable powder.

I. soil requirements for planting

Bean seedlings do not have high requirements for soil. If you want to have a high yield, you need to choose loose and fertile soil with good drainage and rich in organic matter, and the soil PH value should be controlled between 6.0 and 7.5.

Stubble is also critical, and non-legume vegetables such as potato and wheat are usually selected for planting.

II. Rational fertilization

In general, the base fertilizer will choose non-artificially treated farm manure, urea, potassium sulfate and diammonium phosphate for mixing ratio, and the mixing ratio can be determined according to the actual planting area, which can be matched by professionals. you can also consult the proportion in the store where you buy fertilizer.

Third, sowing seeds

Sowing seeds of bean seedlings and vegetables should be selected after treatment, which is conducive to late harvest, usually sowing in spring every year, April is the best time for sowing, sowing is reasonable, and ventilation must be maintained at any time after sowing, which is conducive to the growth of bean sprouts.

IV. Post-management

The main results are as follows: 1. when bean sprouts grow to a certain stage, it is necessary to carry out intermediate ploughing and weeding, which is beneficial to promote the growth and development of roots.

2. Watering in the later stage can increase or decrease appropriately according to weather changes, less watering in frequent rainy weather, watering and fertilization after each harvest in relatively dry weather, excessive watering will lead to root rot, and fertilization is mainly based on nitrogen fertilizer. match other fertilizers properly.

V. Prevention and control of diseases and insect pests

The main diseases of bean sprouts are Fusarium wilt, rust, powdery mildew and so on.

Must be selective to the case, in order to effectively remove diseases and insect pests, powdery mildew can use sulfur suspension, Fusarium wilt can be mixed with carbendazim, rust can be used rust wettable powder.

VI. Timely harvest

1. Bean sprouts must be harvested at 6-10:00 on sunny days, 8-12:00 on cloudy days, but not on rainy days.

2. Bean sprouts can be harvested about 3-4 times a year. Generally, they will be stacked in vegetable baskets or cardboard boxes after harvest. Be careful not to pile them too full.
