High-yield and high-efficiency sorghum cultivation method

Abstract

The invention discloses a high-yield and high-efficiency sorghum cultivation method. By advanced covering of an arched shed and a film, the temperature of a nursery site is increased, sorghum sowing and seedling culture are advanced, sorghum growth and development progress is advanced, the growth period of first sorghum is advanced, double production is achieved in one season, and favorable temperature and light conditions are created for regenerated sorghum growth and development. Particularly, the requirement of sorghum growth for nutrition is met in terms of base charcoal fertilizer application and the like, biomass charcoal fertilizers can enhance soil carbon fixation effects, physical and chemical properties and the structure of soil can be effectively improved, soil quality and fertility are improved, the yield of sorghum crops is increased, fertilizing and watering are repeatedly performed in management to prevent premature senescence, axillary bud differentiation is promoted, early growth and quick tillering of regeneration seedlings are promoted by the aid of suitable stubble height, the density of low-position regeneration seedlings is timely determined, steady growth ofthe regeneration seedlings is promoted, and a solid foundation is laid for high yield. The cultivation method is simple, easy, high in economic benefits and worthy of popularization, and large-scale cultivation can be performed.

Description

Technical field [0001] The invention relates to the field of cultivation technology, in particular to a high-yield and high-efficiency cultivation method of sorghum. Background technique [0002] Sorghum is an important dryland food crop in my country. Compared with other major food crops, sorghum has unique biological characteristics and economic advantages: high photosynthetic efficiency, outstanding stress resistance, and strong heterosis. Sorghum can be used for edible, feed, and processing. Famous Chinese wines such as Moutai, Wuliangye, Fenjiu, Luzhou Laojiao Special Qu are brewed with sorghum as the main or auxiliary material. Chinese sorghum has undergone a long period of natural and artificial selection, forming a variety of varieties, divided into grain, brewing, feeding, sugar, broom, stalk and so on. Due to the differences in climate, soil, and cultivation systems in sorghum cultivation areas, the diversity of cultivated varieties is also different. With the long hi...

Problems solved by technology

With the long history of sorghum planting, growers use natural seeds, the phenomenon of variety degradation is relatively serious, and the planting technology is backward, which is mainly reflected in the poor quality of seeds. There are no formal seed selection standards and seed selection bases. Seed treatment, insufficient soil fertility in seedbeds, and the use of open-air seeding to raise seedlings are 15-20 days later, resulting in a delay in the transplantation of sorghum seedlings from late April to early May; long-term use of chemical fertilizers and chemical pesticides, resulting in soil compaction and organic matter content Low, sorghum quality declines, serious damage from diseases and insect pests, serious environmental pollution, decline in agricultural sustainable reproduction capacity, decline in sorghum output, and ecological balance imbalance

The late transplanting and planting of sorghum leads to a decrease in the survival rate of sorghum seedlings, and the mature harvest time is about 15 days later, which intensifies the damage of sorghum ear borers in the later period, which is not conducive to high yield and high quality of organic sorghum, and the late harvesting period cannot realize sorghum regeneration twice In view of this phenomenon, a new cultivation method is needed in order to obtain high yield, high yield and good quality of sorghum to maximize economic benefits
