Sorghum seedling and transplanting method

Abstract

A sorghum seedling and transplanting method comprises the following steps of selecting a land for a seedbed and manufacturing the seedbed, selecting broadcasting time, managing seedbed, and emptying soil, transplanting and managing fertilizer application. A leeward and sunny vegetable land with fertile and loose soil is selected for the seedbed land; compartments with the width of 4.5 chi is formed and compartment trench is 0.5 chi wide; spring-sowed sorghums are broadcast from the last ten-day of March to the beginning of April and seedlings are nursed and summer-sowed sorghums are broadcast from the first ten-day of May to the middle of May and seedlings are nursed; seedlings are thinned when three to four leaves grow; seedling distance is 3 to 5cm; seedlings with ages of 20 to 30 days and having 6 to 8 leaves are transplanted; the line distance of soil-emptied sorghums is 1.5 to 1.8 chi and a nest distance is 0.8 to 1 chi; 4,000 to 5,000 nests are formed for each mu and two plants are placed in each nest; 1,000 to 1,500 kg farmyard manure is applied for base fertilizer for each mu; and 20 to 25 kg composite fertilizer is applied. Growth seasons and land force can be fully utilized and cropping index can be increased; early-maturation can be improved; lodging can be prevented and sorghum output can be increased; and about 50kg sorghum can be increased for each mu compared with a common transplantation method.

Description

technical field [0001] The invention relates to sorghum planting technology, in particular to a sorghum seedling raising and transplanting method. Background technique [0002] Sorghum is a high-efficiency C4 crop with drought and waterlogging tolerance and wide adaptability. 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 this area, and it has largely solved the food security problem in this area. Sorghum can also be used to make wine, and the wine it brews is often high-end wine. In order to increase the yield of sorghum, sorghum planting methods are also various. Wherein the sorghum seedlings are transplanted to improve its effective absorption of soil during the transplanting process, and this method can increase its yield. However, the current method of raising sorghum seedlings and transplanting simply completes the raising and transplanting of sorghum seedlings, but t...

Problems solved by technology

However, the current method of raising sorghum seedlings and transplanting simply completes the raising and transplanting of sorghum seedlings, but there is no reasonable control over the process, and the sorghum yield is not increased. The result is not ideal
