Abstract

The invention relates to a cultivation method of sorghum. The cultivation method comprises the following contents: A, seed cultivation; B, a sowing cultivation method in spring and in summer: a) sowing; b) controlling the density; c) fertilizing; d) performing field management and harvesting; C, a regeneration cultivation method. Parent seeds of the sorghum provided by the invention are systemically selected from Honeyingzi sorghum plants; the yield of the sorghum is significantly higher than that of the Honeyingzi; the main reason for yield increase is significant increase in the number of grains per spike, with an average increase of 150 grains per spike; the thousand seed weight is also significantly increased by about 1 gram. A sorghum variety cultivated by the cultivation method has the plant height being about 260cm, which is about 20 cm lower than the plant height of the Honeyingzi; the lodging resistance of the variety is enhanced, so that mechanized harvesting is facilitated; the variety is high in amylopectin content, strong in glutinousness and moderate in tannin content; when the variety is applied to wine brewing, the wine yield is high and the wine quality is good.

Description

technical field [0001] The invention relates to the field of planting high-quality edible grain plants, in particular to a method for cultivating sorghum. Background technique [0002] The main utilization parts of sorghum are grain, rice bran, stalk and so on. Among them, the main nutrient content in the grains: 3% crude fat, 8-11% crude protein, 2-3% crude fiber, and 65-70% starch. Sorghum rice is rich in nutrients and can be used to steam rice and cook porridge. It is beneficial for patients with chronic diarrhea to often eat sorghum rice porridge. The yield of sorghum in the three northeastern provinces is relatively high. Hunan province and the sorghum region in southwest my country have ecological environment characteristics such as many mountains, barren land, seasonal drought and extensive cultivation. A characteristic of harvesting two stubbles. However, the main varieties used in production currently lack varieties that are resistant to moderate dense planting, h...
