How to mulch the latest pumpkin planting

Pumpkin cultivation is very common in China, although the pumpkin planting method is simple. But when we are planting, we also need to do a good job of management. Among them, plastic film mulching is very important for the growth of pumpkin, which is related to the yield and quality of pumpkin. So how to cover plastic film when growing pumpkins? Today, the editor will give you a brief introduction. Let's take a look at it.

1. Characteristics of film mulching

When growing pumpkins, plastic mulching is mainly needed to protect the roots of pumpkin plants. Because plastic film mulching does not have the effect of releasing frost, if it is cultivated in the open field, it should be carried out after the frost is broken. Generally covered before and after Ching Ming Festival, reasonable plastic film mulching can improve the growth ability of pumpkin roots, promote deep roots and cultivate strong seedlings. And the row spacing of pumpkin planting is generally large, so the rate of return is also relatively high. Because plastic film mulching has to go through summer, the temperature in summer is very high, so pumpkin varieties should be mainly heat-resistant.

2. Land preparation

Pumpkin is planted after plastic film mulching. In order to avoid problems such as overgrowth, lodging and early senescence, we should focus on land preparation. Try to advance the deep turning time of the soil, rake the soil after the beginning of spring, improve the soil moisture conservation capacity, and ensure that the ground is flat without obvious clods. After leveling it, dig a ditch about 20cm wide in the place where the pumpkin is to be planted, and the ditch depth is controlled at about 18cm. Then apply sufficient farm manure in the ditch, and then properly water the soil to form a high ridge. Break up the soil on the ridge and remove everything that will pierce the plastic film.

3. Film mulching method

After the pumpkin bed is done, the plastic film should be covered in time. It can improve the ability of soil moisture conservation and temperature increase, and plastic film mulching can not be selected on cloudy and rainy days. Should be carried out in a sunny day when the temperature is high, because if the film is covered in a low temperature environment, then in a sunny day, if the thermal expansion of the film is blown by the wind, it is easy to break. When covering the film, we should pay attention to slowly unfold, pull the film flat and tight. Let the plastic film be completely close to the ground, and then press both sides of the plastic film with soil. 20cm is not covered with film between ridges and ridges, which is convenient for watering in the later stage.

4. Film mulching and colonization

For pumpkin cultivated with plastic film mulching, the planting method can be seedling transplanting or direct seeding. There are two methods of planting, first of all, you can cover the film directly on the field, and then plant the seedlings in the plastic film according to the row spacing of the planting plants. You can also plant the seedlings first and open them according to the position of the seedlings when covering the film. Cover about 80% of the soil at first, then water it properly and then cover it flat. The planting holes in the plastic film should also be pressed strictly with soil. If it is covered with film after sowing, then when the seedlings are unearthed, they should make a cut in time to promote the breaking of the seedling membrane.

The above is a brief introduction to how to cover pumpkin with plastic film. That's all for today's introduction. This article is for reference only. I hope it can help you all.
