Cowpeas are grown in many rural homes because one plant can produce three to four fruits, has a high yield, and are delicious. People like to stir-fry cowpeas with minced meat, and mix them with noodles when eating, which tastes delicious. When planting cowpeas, ground film must be used. Why is this? Let's take a look!

What are the benefits of mulching cowpea cultivation?

The planting area of ​​cowpea in my country is getting larger and larger. Various soil-borne diseases and insect pests are the main factors affecting the high quality and high yield of cowpea. When planting cowpea in spring, mulching with mulch can increase temperature and keep warm, retain moisture, resist drought, prevent waterlogging, prevent soil compaction, and increase the ability of soil to retain fertilizer. Secondly, mulching with mulch can improve the physical properties of the soil, reduce the harm of salt and alkali, prevent weeds, reduce diseases and insect pests, promote nutrient conversion, and play a role in preventing cold, promoting early maturity of cowpea, and increasing cowpea yield.

Advantages and disadvantages of using colorless transparent mulch

Advantages: When planting cowpeas, the temperature must be stable above 10℃ before sowing and the seeds can germinate. Colorless transparent mulch can increase the temperature of the soil layer by 3-6℃, so cowpeas can be sown in advance, and cowpeas can mature faster and be put on the market earlier. Colorless transparent mulch can enhance the light between plants near the ground, increase the concentration of carbon dioxide in the soil, and is conducive to the growth of plant roots.

Disadvantages: When there are water droplets on the colorless transparent mulch film, or when it is contaminated by dust, the light transmittance of the film will drop by about 50%. Colorless transparent mulch film is prone to weeds, so certain weed control measures must be taken when planting cowpeas.

What is the role of cowpea mulch cultivation?

Generally, mulch cultivation can increase the soil temperature by 2-5 degrees Celsius in winter and spring, and in the hot summer, it can reduce the soil temperature by about 3-6 degrees Celsius. The disadvantage is that it is afraid of heavy rain, which will harm seeds and seedlings, so drainage measures need to be taken. Generally, the height between the mulch and the gully soil is preferably 10-15 cm. When the soil surface temperature is appropriate, it can promote the decomposition of fertilizers and the germination of seeds.
