Abstract

The invention relates to a method for planting sorghum, and belongs to the field of plant cultivation. The method includes planting germinated sorghum seeds in soil with the pH (potential of hydrogen) of 6.4-6.6 and cultivating the germinated sorghum seeds in the soil. The method particularly includes steps of sieving the soil to obtain broken soil, measuring a pH value of the soil, regulating the pH of the soil until the pH of the soil reaches 6.4-6.6, adding water into the soil and stabilizing the soil for 3-7 days; applying fertilizers to the soil and stabilizing the soil for 1-4 days to obtain cultivation soil; soaking sorghum seeds in alcohol for 3-6 s, then cleaning the sorghum seeds by water, placing the seeds in culture dishes cushioned with filter paper and then accelerating germination of the seeds in culture tanks at the temperatures of 22-28 DEG C for 3-5 days until the seeds germinate; cultivating the germinated sorghum seeds in the cultivation soil, spraying water and then cultivating the germinated sorghum seeds in culture tanks in greenhouses. The method has the advantages that the pH of the soil for planting the sorghum seeds is regulated until the pH of the soil reaches 6.4-6.6, accordingly, biological nitrification inhibitors secreted by rhizosphere of the sorghum can be maximized, nitrogen cycle can be regulated and controlled, the nitrogen utilization can be improved, and soil greenhouse gas can be reduced.

Description

technical field

[0001] The invention relates to a sorghum planting method and belongs to the field of plant cultivation. Background technique

[0002] Sorghum, also known as red grain, is one of the dryland food crops in my country. It is not only food for people, but also good feed for livestock and the main raw material for wine making. Sorghum is rich in nutrients. In addition to being used for wine making, food and feed, it is also widely used in the sugar processing industry. Sorghum brooms can be used as broom handles, and sorghum stalks can be made into plywood as building materials. Sorghum is really a treasure. In order to increase the yield of sorghum, a large amount of nitrogen fertilizer is often applied, because the nitrate nitrogen formed by nitrification in the nitrogen cycle is easily affected by leaching and denitrification, resulting in serious nitrogen loss and surface water pollution. and damage to the ecological environment. Although some nitrogen fer...
