Cultivating method for direct sowing of sorghum

Abstract

The invention discloses a cultivating method for direct sowing of sorghum. In length, every three jins of seeds are sowed on one mu of field, and the mulch thickness ranges from 1 cm to 3 cm; spring sowing is selected to be carried out before and after the Pure Brightness, summer sowing is selected to be carried out after the summer harvest, the sowing is carried out when soil is still wet in time, thinning is conducted early, and seedlings are divided evenly and strong seedlings are kept when the seedlings grow to have 3-4 leaves; when the seedlings grow to have 5-6 leaves, final singling is carried out in the mode that 2-3 plants of seedlings are sowed in each nest according to soil fertility, fertilization level and thickness of sowing, and it is guaranteed that 8000-12000 plants per mu of the seedlings are sowed in a pure cropping mode or 8000-9000 plants per mu of the seedlings are sowed in a relay intercropping mode; after the final singling is conducted, 20-30 dans of clean dung and 2-3 jins per mu of urea are utilized, dressing of hole applied fertilizer is conducted, first time intertillage soil loosening is conducted by being combined with weeding, before jointing, dressing of joint and booting fertilizer is conducted deeply, and third time ridge plowing is conducted by being combined with intertillage. Growing seasons and land capability are sufficiently utilized, planting steps are reduced, the labor is saved, land resources are effectively utilized, the sorghum yield is improved, the produced sorghum is high in quality, and the nutritive value is high.

Description

Technical field [0001] The invention relates to sorghum planting technology, in particular to a direct seeding sorghum cultivation method. Background technique [0002] Sorghum is an annual herb, with thick stalks, upright, with supporting roots at the base nodes; sexual preference for warmth, drought resistance, and waterlogging tolerance; it can be divided into edible sorghum, sugar sorghum, broom sorghum, etc. according to characteristics and uses. Edible sorghum grains for food and wine; sugar sorghum stalks can be made into syrup or raw food; broom sorghum ears can be made into brooms or cooking brooms; tender leaves can be dried in the shade or dried for feed; caryopsis can be used as medicine , It can dry dampness and expectorant, calm the mind and calm the mind. Belongs to cash crops. It is widely planted in the south of my country, especially in the mountains of the Yunnan-Guizhou Plateau. It is one of the main food products in the region, which largely solves the food...

Problems solved by technology

Direct-seeding sorghum cultivation is one of the planting methods. This method is relatively common. At present, this method is also used in many places to plant sorghum. Most of them are conventional planting. There is no reasonable arrangement of planting timing and reasonable management, resulting in the production of sorghum planted. improve, the result is not ideal
