In the process of planting cucumbers, there is a problem that is easily overlooked by everyone, that is, the choice of mulch. In fact, the selection of the film is good, has a great impact on the yield of cucumber, so how to choose the film to grow cucumber? Let us take a look at the situation of Zhang Dazhao below. You cucumber, I don’t think this year’s production will be too high.†The big sister listened to me and stopped. “Teacher, where do you see that my cucumber is not producing high? I don’t believe it.†Zhang Daqilian After planting cucumber for three years, the output is not too high. In fact, she is not clear. The main reason is that it is on the purchased mulch. Zhang Daxiao said with a smile, "You said that I bought a fake mulch." ?" The mulch film purchased by Zhang Dazhao is not a fake mulch film. The problem is that the selected mulch film is wrong. Many growers only pay attention to fertilizers, pesticides, etc., and the choice of mulch is more random. Choosing the right mulch film is very effective in increasing the yield of cucumber. Under normal circumstances, there are three kinds of mulch films sold on the market, and many growers are not very clear about the function of each type of mulch. 1, the function of colorless film It has the highest light transmittance, in addition to moisturizing, it has a good effect on soil warming and can increase soil temperature by 2-4 degrees. The fly in the ointment is that it is easy to produce weeds under the film. This should be noted. 2, the function of black mulch The black film has a very low light transmittance, and its advantage is that the weed control effect is good. The disadvantage is that the soil warming effect is the worst, generally about 2 degrees. 3, the function of silver gray film The biggest advantage of silver-gray mulch is that it has good insulation effect and the strongest reflection, which can enhance the light at the bottom of fruits and vegetables. It can also avoid aphids and prevent the occurrence of viral diseases. However, soil warming is the worst. The silver-gray mulch is suitable for summer use, and it is very inappropriate for Zhang Datun to use this mulch in winter. After reading it, do you know how to choose a film?
