Embodiment 1

[0020] Example 1: As attached Figure 1~2 As shown, a corn rainwater harvesting and mulching planting method includes the following steps: 1. digging a hole; 2. sowing; 3. mulching; 4. covering the seed; 5. pressing the film.

[0021] In the first step, dig rain-harvesting sowing holes in the soil plow layer. The rain-harvesting sowing holes are planted in wide and narrow rows, with a wide row spacing of 80cm, a narrow row spacing of 40cm, and a column spacing of 40cm. The diameter of each rainwater harvesting sowing hole It is 10cm and the depth is 10cm.

[0022] In the second step, the compound fertilizer is used as the base fertilizer, and two selected corn seeds are sown in each rain-harvesting sowing hole, and the distance between the base fertilizer and the seeds is 3 cm.

[0023] In the third step, the soil surface around every four rows of rain-collecting sowing holes 1 is leveled, and a 1.8 m wide mulch film 3 is covered on the flat soil surface and the four rows of rain-co...

Abstract

The invention discloses a rain collecting and film mulching planting method for corn. The method comprises the following steps of 1, digging holes; 2, conducting sowing; 3, conducting film mulching; 4, covering the seeds; 5, pressing films. In step 1, the rain collecting and sowing holes are dug in a soil tillage layer and adopt a planting mode with wide and narrow rows, the spacing of the wide rows is 80 cm, the spacing of the narrow rows is 40 cm, the column spacing is 40 cm, the diameter of each rain collecting and sowing hole is 10cm, and the depth of each rain collecting and sowing hole is 10 cm. By means of the method, the number of weeds can be effectively reduced, the harm caused by use of herbicide to soil is reduced, production reduction caused by severe drought is prevented, theeffects of raising the temperature and preserving the moistening are good, and remarkable results of on-site planting are achieved.

Description

Technical field [0001] The invention relates to a corn planting method, in particular to a corn planting method with rainwater harvesting and mulching, belonging to the technical field of crop planting. Background technique [0002] Corn is the main food crop in my country. The production of corn is directly related to my country’s food security and farmers’ income increase. In recent years, most of the corn planting process has been planted with traditional film mulching methods. Although certain effects have been achieved, it is still There are certain problems, such as poor sowing quality, irregular emergence, unreasonable water and fertilizer input, prone to drought, overgrown weeds in the growing season, and low yield. Therefore, how to solve the problem of reducing the use of pesticides and efficiently using water and fertilizer during the growth of corn has become an urgent problem. Summary of the invention [0003] The technical problem to be solved by the present inventio...
