Why do cowpeas need to be broken to plant seedlings? Should white or black mulch be used for cowpeas?

Cowpea has strong growth ability and grows in tropical and subtropical regions. It is one of the oldest vegetable crops in the world. Cowpea is delicious whether it is eaten cold or stir-fried. It can be eaten in many ways and is an indispensable vegetable on the dining table of many families. Below is some information about the mulch film when planting cowpea. Let’s take a look!

Why do cowpeas need to break the film and release the seedlings?

When the cowpea seedlings grow up, the film must be broken and the seedlings released in time, otherwise the cowpea seedlings may be burned to death. So when should the film be broken and the seedlings be released? The time is after the cowpea seedlings turn green and the weather becomes warmer. After breaking the film and releasing the seedlings, it depends on the growth of the cowpea. Those that need to be supplemented should be supplemented, and those that need to be removed should be removed. Then fertilize again. Of course, the previous base fertilizer cannot be saved. In this way, the spring mulch cultivation is completed.

When planting cowpea, should I choose white or black mulch film?

If you use white mulch, you must deep plow and weed before covering the film. If the weeds grow densely in the area, I suggest you use black mulch. If the land is seriously infested with insects, I suggest using silver-white mulch.

After sowing, the ground film must be covered and compacted. If there are small holes, they must be filled. Otherwise, if the ground film is airy, it will not be able to keep warm. After all these are done, they must be checked in real time to prevent damage to the ground film in the later stage.

You must pay attention to the weather when breaking the film and releasing the seedlings. If the weather is likely to get cold at any time, then you can only delay the time of breaking the film and releasing the seedlings. And the opening of the film should not be too large. Generally, a two-finger-wide opening along the direction of the cowpea seedlings is enough.

When can I plant cowpea?

After the ground film is laid, it is necessary to sow the seeds. As for the time of sowing, it is best to do it 2 to 3 days after the ground film is laid. When obvious small water droplets can be seen on the ground film, it means that the temperature and humidity in the soil have reached the requirements for sowing cowpeas, and it is best to sow them at this time.

If it rains a little after laying the ground film, it would be even better. After all, that's what the saying goes "Plant melons and beans around the Qingming Festival."
