Problems solved by technology

During the growth of crops, they are inevitably threatened by insect pests. In order to prevent damage to crops caused by insect pests, pesticides must be sprayed at intervals, which will not only easily cause environmental pollution, but also cause pesticide residues in crop fruits.

Embodiment 1

[0010] Example 1 Planting of ginger

[0011] Ginger of the same variety is planted in adjacent plots A and B. Both plots A and B have the same area of ​​1 mu, and the planting conditions such as soil moisture are the same. Before planting, the two plots A and B were subjected to high-temperature pest control and conventional fertilization, and both plots were sown by conventional sowing methods. After sowing is completed, plot A is grown in the open air until harvest. After the sowing of plot B is completed, support rods are erected around and above it to form a mesh frame, and then a mesh with a mesh size of 15 meshes is laid on the mesh frame to form a mesh cover that completely covers the surrounding and above plot B. , the height of the top surface of the net cover from the ground should not be lower than the height of the operators in the net cover, 1.8m-2.5m is appropriate, and the net cover should be removed when harvesting.

[0012] During the whole growth period of ...

Embodiment 2

[0013] Example 2 Planting of tomatoes

[0014] Tomatoes of the same variety are planted in adjacent plots A and B, with the same area of ​​0.5 mu, and the same planting conditions such as soil moisture. Before planting, the two plots A and B were subjected to high-temperature pest control and conventional fertilization, and both plots were sown by conventional sowing methods. After sowing was completed, plot A was grown in the open air until the end of the tomato harvesting period. After the sowing of plot B is completed, support rods are erected around and above it to form a mesh frame, and then a mesh with a mesh size of 20 meshes is laid on the mesh frame to form a mesh cover that completely covers the four sides and above of plot B. , the height of the top surface of the net cover from the ground should not be lower than the height of the operators in the net cover, 1.8m-2.5m is appropriate, and the net cover will be removed after the harvesting period of tomatoes.

Abstract

The invention discloses a method for planting crops in a screen manner, which comprises the steps of: after crops are planted, erecting a net on and around the crops to form a mesh enclosure to ensure that the crops grow in the mesh enclosure; and when the fruits of the crops are harvested, removing the mesh enclosure, wherein the black regions formed by the weaving of black wires and white regions formed by the weaving of white wires are arranged on the net, and the black regions and the white regions are shaped as strips and arranged at intervals. The invention has the advantages of increased yield due to reasonable illumination on the crops, capability of effectively avoiding pests without spraying pesticides, no pesticide residue on the fruits of the crops, realization of non-polluted planting, low moisture losing speed and strong drought-enduring capacity.

Description

technical field [0001] The invention relates to a method for planting crops, in particular to a method for planting crops by using a net cover. Background technique [0002] During the suitable growing season, crops are mostly planted and grown in the open air. Light is the energy source for crops to carry out photosynthesis, and is a necessary condition for chloroplast development and chlorophyll synthesis. Light can regulate the activity of certain enzymes in crops, so light has a great impact on the growth and development of crops. There is no fixed proportional relationship between light and crop photosynthesis, but within a certain range of light intensity, when other conditions are met, with the increase of light intensity, the intensity of photosynthesis also increases accordingly. However, when the light intensity exceeds the saturation point of light, the light intensity increases again, but the photosynthesis intensity does not increase. When the light intensity ...
