Abstract

The invention discloses a method for cultivating crops by using a liquid mulching film, and belongs to the technical field of crop planting. The method comprises the following steps: preparing a liquid mulching film forming liquid and a cultivated land soil conditioner; turning soil; and pretreating seeds: soaking corn seeds with chlormequat chloride for 4-8 hours first, then soaking the corn seeds in a mixture containing sodium alginate, chitin, redispersible latex powder and turbid liquid at 30-45 DEG C, fishing out the corn seeds, soaking the corn seeds in water at a temperature of lower than 4 DEG C for 5-60 seconds, then fishing out the corn seeds, and draining water to dry the seeds at 20-30 DEG C. The planting method provided by the invention has the advantages of wide source of rawmaterials, low price and convenient transportation, reduces the production cost of corn, can effectively improve the yield of corn, and makes it feasible to popularize corn planting in saline-alkaliland.

Description

technical field [0001] The invention relates to the technical field of crop planting, in particular to a method for cultivating crops by using liquid plastic film. Background technique [0002] Saline-alkali land refers to the salt contained in the soil that affects the normal growth of crops. Soil salinization is a worldwide problem. The saline-alkali soil area in the world is about 1 billion hectares. my country has 99.13 million hectares, or about 1.47 billion mu. More than 100 cities in the country are located in saline-alkali soil distribution areas. Nearly 500 million mu of land has been reduced or abandoned due to salinization, mainly concentrated in the arid and semi-arid regions of North China, Northwest China and Northeast China. In addition, during the cultivation process, the long-term excessive application of chemical fertilizers leads to the intensification of secondary salinization of the soil, serious compaction, and the continuous expansion of salinized and ...
