Vegetable mulch cover five attention
First, pay attention to choose the film. According to different seasons, crop types, the purpose of covering the film to choose different mulch. For the purpose of warming and moisturizing, transparent thin film can be selected.

Second, pay attention to soil moisture management. Before the mulch is covered, the moisture in the soil should be sufficient and the sensation is good, which is also the key to ensure the normal growth of seedlings and seedlings. If the soil is heavy, the water content is high, and oxygen is lacking, it will be detrimental to seed germination and root growth. Such plots should be aired first, and when the humidity is appropriate, the plastic film should be covered so as not to damage the roots. Third, pay attention to intensive cultivation and smoothing. Soil crop stalks and debris will break through the mulch, not only failing to cover the purpose of the mulching film, but also being easily rolled by the wind.

It is best to sow before the final frost period, and the emergence after the frost period is beneficial to increase production and income. Fifth, pay attention to fertilization, and some farmers believe that the cover film can increase production, so less fertilizer, fertilizer, fertilizer consumption is also very small, resulting in late defermentation, affecting crop growth. Therefore, fertilization according to crop fertilizer requirements formula fertilization, Shizuo Qi. Organic manure should be thoroughly cooked to avoid burning roots.
