Matters needing attention in cowpea planting

Cowpea is what we often call long beans, most of its nutrients are vitamins, although it can be eaten raw, but it can be poisoned if it is undercooked when cooking. Now we all like to eat sour beans, especially in summer, and have the effect of relieving summer heat, so basically many people plant cowpeas, and today's pro-agriculture network wants to tell you some problems that we need to pay attention to when planting cowpeas. Let's take a look.

1. Select improved varieties

Now it can be said that there are not hundreds of cowpea varieties, but each cowpea has its own advantages, such as high yield, good quality, good disease resistance, and so on. in fact, these are based on the local environment, in fact, the cowpea varieties are very good, but the growth performance is different in different environments, so we need to select varieties according to the local climate. The second is to pay attention to understand the market situation, to see which variety of cowpea is more popular, more competitive, choose the most economically valuable variety to plant.

2. Seed treatment

Cowpea seeds are picked from mature beans, so we need to deal with the seeds before planting. First, we take the seeds out of the pods to remove impurities, then soak the seeds in water for about 20 minutes, rinse with clean water three or four times, drain the water, and germinate at a suitable temperature. After most of the seeds germinate, they can be sown in the field. This can greatly improve the emergence rate of seeds and enhance the resistance of seeds at the same time.

3. Reasonable density

Cowpea planting must pay attention to the rationality of density, otherwise if the planting is too dense, then many bean seedlings do not have light, so the probability of pods will be reduced, and in serious cases, cowpea seedlings may die. Secondly, the purpose of doing so can also enhance the ventilation of the field, so that the field will not look so gloomy. Then the best planting density is 30 cm between each plant and 50 cm between each row, so that they can be extended by a certain amount of space.

4. Watering and fertilization

Watering needs to be carried out according to the growth of bean seedlings. if the bean seedlings are newly emerging, they will basically be watered every other week or so, but after the bean seedlings grow, they will need to be watered according to the humidity in the field. if the land is dry, it needs watering, and if Rain Water has more water, it will be drained. But more water is needed when the seedlings blossom and produce pods. One fertilization is needed after planting, mainly using urea, and the second fertilization is needed when the plant grows to about 40 centimeters. This fertilization usually uses fecal and urine water, and the third fertilization is when the plant blossoms. We can choose to use potash and phosphate fertilizer. Since cowpeas are harvested in batches, we all have to apply fertilizer after harvest to promote the growth of the next batch of cowpeas.

5. Pruning and framing

In order to improve the pod rate of cowpea, we need to prune and frame the bean seedlings when they grow to a certain period of time. Generally, when the bean seedlings grow to 40 to 50 centimeters high, we need to put up a support next to the bean seedlings and let the bean seedlings grow along the support. This can not only increase the yield, but also reduce some diseases and insect pests. When the bean seedlings begin to bear cowpeas, we can remove the leaves in some places where they are denser, which can increase the density and enhance the permeability between cowpea seedlings, which is not easy to cause the disease.
