Spread plastic tape in the field, plants are easy to get hurt! The measured temperature soared to 78 degrees Celsius, and the root system floated, scalded and fatted.

Silver black plastic cloth is often seen in the fields, and one field after another is completely covered to prevent the spread of weeds, which is a convenient and cheap way for farmers. However, when tested in the field, at noon, the temperature of the plastic cloth was as high as 78 degrees Celsius, and the airtight plastic cloth clung to the soil, which not only caused the plant roots to float, but also easily caused burns to the whisker roots and excessive soil temperature.

The secret of reviving the dead in the park lies in foliar fertilization and artificial weeding.

"the farmer originally said that he had to spray herbicide, and the fields had to be covered with plastic tape. I wanted to give up my assistance to her for a time." When Chen Xingzong came to the third field, he pointed out that the condition of the field was bad, and the farmers were about to give up, but Chen Xingzong gave advice and continued to do foliar fertilization and fruit thinning. "this garden has been saved, even the most beautiful root system in the field I have seen today."

However, Chen Xingzong also said that part of the reason is that the growth stages of each park are different. Because the park is still at the front end of the growth stage, it does not need to waste energy on the fruit, so it can concentrate on developing the root system, and the natural root system is relatively healthy.

If you want to lay plastic cloth, you should place the bottle and match it with artificial weeding and foliar fertilization.

There were not many Rain Water in the early part of this year, so the root system floated up, and the condition of heat and scald was not serious. On the contrary, because of the lack of rain, the root system looked for water to take root, and the root system scalded less. In addition, even if plastic sheets are laid in the fields, the root system is different because the soil, crop growth stages and herbicide management are different in different fields.

Chen Xingzong says that for example, the soil is divided into clayey soil and sandy soil, which is finer and easier to retain water, and the temperature rises more slowly. Sandy soil is easy to lose water, and it is easier to reach the temperature that harms crops than when exposed to sunlight. Sandy soil coupled with the laying of plastic cloth, as soon as the sun exposure temperature rises, crops such as fever, root and rhizosphere microorganisms are damaged, crops are prone to withering and aging.

Although laying plastic cloth has many disadvantages, it is difficult for farmers to change their habits. Chen Xingzong also suggests that at least put a special bottle under the plastic cloth, combined with foliar fertilization and manual weeding.
