Matters needing attention for the latest pumpkin covered with plastic film

Pumpkin is a kind of popular melon vegetable in our country, so the planting area is relatively large in our country. When growing pumpkins, some basic management is still very important. Among them, plastic film mulching can increase the yield of pumpkin and expand the planting efficiency. However, there are a lot of precautions when covering plastic film. So what exactly is there? Let's take a look at it.

1. Apply sufficient base fertilizer

Pumpkin has a large demand for fertilizer and nutrition in the process of growing. Therefore, fertilization is still quite important, but because it is not convenient to carry out the work of ploughing and topdressing after mulching plastic film. Therefore, in order to ensure adequate growth and nutrition of pumpkins, adequate base fertilizer should be applied before covering plastic film. Fertilizers are generally based on slow-acting fertilizers to avoid the phenomenon of burning seeds and roots, resulting in the excessive growth of pumpkins. As far as possible deep application, if the fertilizer is too shallow, then it is very disadvantageous to the deep root. If there is a lack of fertilizer in the later stage of pumpkin growth, then it is necessary to apply appropriate topdressing or foliar fertilizer.

2. Timely watering

After the pumpkin is covered with plastic film, the pumpkin seedlings can receive less water from the outside world. Therefore, before covering the film, we should pay attention to the soil moisture, the soil moisture should be kept in the hand can be pinched into a mass, thrown to the ground can be dispersed. When mulching with plastic film, if the soil water content is insufficient and is not watered in time. Then after plastic film mulching, the soil temperature will gradually rise, and the soil moisture will rise. The soil layer below 6-9 cm is prone to drought, so we should pay attention to timely watering to avoid premature senescence of pumpkins due to lack of water.

3. Planting density

After plastic film mulching, pumpkin seedlings are prone to overgrowth, so we should also pay attention to the planting density of pumpkin seedlings. The density of pumpkin planted with plastic film is slightly lower than that of pumpkin cultivated in open field. We should also pay attention to the method of film mulching, because the effect of film mulching is directly related to the method of film mulching. When covering the film, the plastic film should be flattened and tightened, and then compacted. If the plastic film is ruptured, then it should be covered with soil in time. And it is best to spray herbicides before covering the film, otherwise it is not convenient to weed in the later stage.

4. Mulching time

When using plastic film mulching to grow pumpkins, they are vulnerable to frost. Therefore, we should also pay attention to the time of plastic film mulching, and first of all, pumpkin seedlings should be planted after the late frost. If it is a live broadcast, try to control the frost before sowing and the emergence of seedlings after the frost. If you cover the plastic film, then it is necessary to cover until the harvest, it is best not to remove the plastic film in the middle of planting, and remove the residual film in time after the pumpkin harvest.

The above is a brief introduction to the matters needing attention of pumpkin covering plastic film. This is the end of today's introduction, this article is for reference only, I hope it can be helpful to everyone!
