1. Tilling, sowing and reasonable dense planting. Cowpea is afraid of waterlogging, it should be planted in the field of neutralized soil or sandy soil with high topography, excellent drainage, and no legume crop has been planted for 2 years. The soil should be y dried and whitened to a depth of 33 centimeters when the ground is turned over and the beds should be raised in a concave furrow. Cowpea sowing method and planting relative density can be based on different seasons and different kinds of flexibility to grasp, the general choice of direct seeding method.
8-10 days after sowing, when the first pair of cowpea seedling leafing out, it is necessary to transplant immediately; you can also cover the beds with mulch after sowing to raise the soil temperature. Rationally dense planting is one of the main reasons for increased cowpea yields. Green cowpeas have thin leaves and few branches, so they can be planted more densely; white cowpeas have large leaves and more branches, so they should be planted as sparsely as possible. Generally, the bed width is 1.67 meters (with ditch), double row planting, sowing 2 seeds per hole, plant spacing 10-16.7 centimeters. You can also choose a single row of planting, between the beds can be planted cabbage, cabbage and so on.
2. Effective fertilization. Adequate bottom fertilizer, especially phosphorus and potassium fertilizer, has a better effect on the growth of cowpea, generally 1 mu of organic fertilizer 1000-1500Kg, 50Kg of compound fertilizer. cowpea in the flowering of pods before the provisions of fertilizer is very little, as far as possible to manipulate the early liquid fertilizer, inhibit plant nutrients to grow, if the seedling is indeed weak, can be thinly applied to 1-2 times of urea solution or big If the seedlings are indeed weak, a thin application of 1- 2 times of urea solution or manure can be made. Cowpea flowering and podding period to consume a lot of nutrients, the provisions of liquid fertilizer is higher, should be watered, immediately apply heavy fertilizer, 1 mu of fertilizer compound fertilizer 30Kg, phosphate fertilizer 10Kg, potassium chloride 5Kg.
Weekly and then spray manure once a week, in order to promote the abundant growth of the plant and more flowering and more pods. After the pod growth and maturity period, must more and more fertilizer, should be fertilized once again with phosphorus and potassium fertilizer. 1 mu of phosphorus fertilizer 10Kg, or phosphorus fertilizer Xing in wooden pots plus soaking water overnight, with the clear liquid to carry out the extra-root fertilization, in order to reduce the flower drop drop pods: pods after the full bloom, if the plant line must be far from the growth of the plant, it should be strengthened to enhance the management of fertilizer, to promote the branches of the shoots, and to promote the flowering and the buds on the inflorescences that have already been picked once again. flowering and podding to increase the picking period and enhance cowpea production.
3. Immediately insert bamboo poles, lead vines and straighten branches. When the seedlings are gradually spreading (plant height about 33 centimeters up and down), they should be erected. After the erection of the frame should often lead to vine, lead to vine is generally carried out in the morning after 10:00 a.m. on a clear day, according to the anti-second hand orientation of the bean vines around the bamboo pole, the main vine above the first inflorescence of the side of the vine should be taken off, when the plant grows too strong, jeopardize the natural ventilation and permeability, as far as possible, excise the tip of the yellow leaves, diseased leaves, in order to reduce the problems arising from the.
1. First, provide a suitable culture environment for mussels, try to simulate their living environment, and put some fine sand in
