What are the key cultivation techniques for long yardlong beans?
The long yardlong bean, also known as the bean, is one of the vegetables we commonly see in daily life. It can be divided into two types, the long yardlong bean and the rice yardlong bean, and quite a few farmers in our country grow yardlong beans. So how should yardlong beans be planted? Let's take a look at the detailed introduction.
1. Site selection: It is advisable to choose soil with high fertility, deep soil layer, good aeration and high organic matter content. Clear away the remnants and fallen leaves of the previous crop and weeds in the field, and remove insect and pathogen sources from the soil. Deeply plow the land to a depth of 15-25cm; apply sufficient base fertilizer, with about 2500kg of decomposed organic fertilizer and 30-50kg of special compound fertilizer for vegetables per mu; prepare the land and make beds, with a bed width of about 80cm, a ditch width of about 40cm and a ditch depth of 25-30cm.
2. Sowing: According to local climatic conditions, production season, market requirements, production habits, etc., choose varieties with high yield, disease resistance, excellent quality, good pod appearance, uniform length and good marketability, and also ensure that the varietal characteristics are pure. Generally sow from early April to early August, using hole sowing, with three or four seeds per hole, two rows per bed, and a hole (plant) spacing of about 25cm. Water thoroughly before sowing, and cover with 2cm of soil after sowing.
3. Management: After the seedlings emerge uniformly, remove weak and inferior seedlings, leaving 2 seedlings per hole. When the seedlings have five or six leaves, trellises should be set up to guide the vines, using a “”-shaped trellis with a height of about 2m. From 10 days after emergence to the vine-extending stage, apply one or two light applications of farmyard manure such as human excrement and urine according to growth conditions; water about once every 7 days at the beginning of flowering and when pods begin to form, and every 3-5 harvests, apply a topdressing of fertilizer together with watering. Carry out intertillage and weeding, and control pests and diseases.
