How to manage cowpeas after transplanting? A detailed explanation of the latest technical points

Cowpea is what we call long bean in our daily lives, rich in nutritional value, and has a very large market demand in our country. The main planting method for cowpeas is seedling raising and transplanting, which can effectively increase yield and expand planting benefits. Therefore, the management work after transplanting cowpeas is very important, so how exactly should it be managed? Below, the editor brings you the management techniques for cowpeas after transplanting. Let's take a look!

1. Reasonable watering

After transplanting, water well to stabilize the seedlings and improve the survival rate of the seedlings. Then, after the seedlings enter the slow seedling stage in autumn and winter, water once more, and water again after the slow seedling stage ends. Then do a good job of intertillage and hoeing to promote seedling squatting and improve the soil's moisture retention capacity. Be sure to control the amount of watering well; do not water too much, otherwise water accumulation can easily cause seedling death. Later, water reasonably according to the growth stage of the cowpea seedlings, for example, during the bud stage, appropriately use small drip irrigation, and do not water during the early flowering stage. A reasonable watering method can effectively improve the survival rate of cowpea seedlings after transplanting.

2. Scientific fertilization

Before transplanting, we must first apply sufficient base fertilizer, then during the cowpea seedling stage, apply phosphorus cake fertilizer once in the holes, with the amount of cake fertilizer per mu controlled at about 60kg. When topdressing, we should follow the principle of applying less fertilizer before flowering and more after flowering. After transplanting and survival, apply once decomposed farmyard manure as topdressing, with the amount per mu controlled at about 1000 kg. Then after flowering, increase the amount of fertilization and reduce the frequency of fertilization. When topdressing, we should reasonably adjust the fertilizer nutrient ratio according to the growth condition of the cowpeas and soil fertility and other factors, to ensure normal growth of the seedlings.

3. Build the trellis in time

Cowpea is a vining vegetable, so after transplanting we must also pay attention to doing a good job of building the trellis. After transplanting, when the seedlings begin to throw out vines, set up the trellis in time to avoid them tangling with each other, affecting growth, causing flower and pod drop, and reducing yield. The cowpea supports should be inserted at a position about 12 cm from the base of the seedlings, with the support depth maintained at about 18 cm. Then at about 4/5 of the support position, tie a bamboo pole horizontally to guide the vines, letting the cowpeas grow along the trellis. Building the trellis in time can effectively increase cowpea yield, so everyone must pay a lot of attention.

4. Pest and disease control

⟦NL>Pest and disease control is not only something to pay attention to after cowpea transplanting; it is something we must not relax our vigilance about throughout the entire growth period of planting cowpeas. Different pests and diseases appear at different growth stages of cowpeas, and some pests and diseases may even occur throughout the entire growth period of cowpeas. Therefore, after transplanting, we must strengthen management, spray medicine regularly for disinfection, and do a good job of intertillage and weeding. Among them, common pests and diseases include anthracnose, gray mold, and bean pod borer, etc. After transplanting, we should often observe the growth of the seedlings, and when disease occurrence is found, promptly take corresponding measures to control it.

The above is a brief introduction to how to manage cowpeas after transplanting. After transplanting, we should also do a good job of replanting seedlings. For some weak seedlings, diseased seedlings, and dead seedlings, promptly remove them, then replant healthy seedlings of the same growth to improve the full seedling rate and yield. That is all for today's introduction. This article is for reference only, and we hope it can help everyone!
