Planting method of sorghum

Abstract

The invention provides a planting method of sorghum. The planting method comprises the following steps of sowing and seedling growing in the first ten days in March and the middle ten days in March, sorghum three-leave period transplanting, timely topdressing and seedling lifting after transplanted seedlings survive, water amount control, prevention and control of diseases and insect pests and timely harvesting. The planting method of the sorghum improves the capability of retaining soil, fertilizer and water of soil, and sorghum plants are high in light transmittance and ventilation, deep inroot system and high in lodging resistance; on the premise of guaranteeing national food safety, the chemical fertilizer applying amount is reduced, cost is saved and income is increased for farmers,energy is saved for the country, the environment is protected, and agricultural sustainable development is promoted.

Description

technical field [0001] The invention belongs to the technical field of agricultural planting, and in particular relates to a sorghum planting method. Background technique [0002] So far, there is no standard sorghum cultivation model in my country's agricultural system. Sparse planting and unreasonable close planting are the bottlenecks that restrict the high yield of sorghum. Especially when sorghum is tasseling, the three leaves of the sticks receive insufficient light, and the sorghum sticks will be bald and lack grains, resulting in Yield reduction; there is also no standard for farmers to cultivate ridges, blindness and randomness; especially fertilization, most farmers who grow sorghum use traditional methods to fertilize blindly, which not only wastes a lot of resources and pollutes the environment, but more importantly, the utilization rate of chemical fertilizers With the continuous expansion of the quantity, it will be greatly reduced. At the same time, it will caus...

[0002] So far, there is no standard sorghum cultivation model in my country's agricultural system. Sparse planting and unreasonable close planting are the bottlenecks that restrict the high yield of sorghum. Especially when sorghum is tasseling, the three leaves of the sticks receive insufficient light, and the sorghum sticks will be bald and lack grains, resulting in Yield reduction; there is also no standard for farmers to cultivate ridges, blindness and randomness; especially fertilization, most farmers who grow sorghum use traditional methods to fertilize blindly, which not only wastes a lot of resources and pollutes the environment, but more importantly, the utilization rate of chemical fertilizers With the continuous expansion of the quantity, it will be greatly reduced. At the same time, it will cause the sorghum technical leaves to grow wildly and even cause the outbreak of diseases and insect pests, and the phenomenon of lodging is common. Combining various factors, the production cost of sorghum continues to rise, but the yield cannot be improved, and the quality is gradually declining. , more serious is to cause soil erosion and soil compaction and other vicious circles, which seriously threaten the health of contemporary people and the living environment of future generations
