Long beans are grown at high yields, and 5 issues need to be noted

1. Selection of improved varieties

Now there are dozens of varieties of cowpea, but there are dozens of varieties, but each kind of cowpea has its own advantages, such as high yield, good quality, good disease resistance, etc., and these are actually They are all based on the local environment. In fact, the varieties of cowpea are very good, but the growth performance in different environments is different, so we need to select the seeds according to the local climate, and the second is to pay attention to understand the market conditions, To see which variety of cowpea is more popular and more competitive, choose the most economically valuable variety for planting.

2. Seed treatment

The seeds of cowpea 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, and then put the seeds in the medicinal water for about 20 minutes Remove them, rinse with water three or four times, drain the water, and germinate at a suitable temperature. After most of the seeds are germinated, they can be sown to the ground, which can greatly improve the emergence rate of seeds and enhance the Seed resistance.

3. Reasonable density

Cowpea planting must pay attention to the rationality of density, otherwise if the planting is too dense, then many bean seedlings are not exposed to light, so the probability of pod formation is reduced, and in serious cases, the phenomenon of dead seedlings of cowpea seedlings may occur, followed by doing so The purpose is to increase the ventilation in the field, because the field will not look so gloomy. Then the best planting density is 30 centimeters between each plant and 50 centimeters between each row, so that they have a certain extension space.

4. Watering and fertilizing

We need to perform watering according to the growth of bean seedlings. If it is a bean seedling that has just emerged, it is basically watered every other week or so, but after the seedlings grow, we need to water according to the humidity of the field. If the land is dry, then watering is required, and if there is more rain, drainage is required. But when the bean seedlings bloom and pods are needed, more water is needed. One fertilization is required after planting, mainly using urea, and a second fertilization is required when the plant grows to about 40 cm. This fertilization usually uses dung and urine, and the third fertilization is when the plant is blooming , We can choose to use potash fertilizer and phosphate fertilizer. Since the cowpea is harvested in batches, we must apply fertilizer once after harvesting to promote the growth of the next batch of cowpea.

5. Pruning

In order to increase the pod formation rate of cowpea, we need to prun the sprouts when the sprouts grow to a certain period. Generally, when the sprouts grow to 40-50 cm high, we need to put them next to the sprouts. A scaffold allows bean seedlings to grow along the scaffold, which not only improves yield but also reduces some pests and diseases. When the bean seedlings begin to form cowpea, we can remove the leaves in some dense places, which can increase the density and enhance the permeability between the cowpea seedlings.
