Method for using regeneration capacity of Chinese sorghum

Abstract

The invention relates to a method for using the regenerative capacity of broomcorn. The method is characterized in that: first broomcorn seeds are sown during a period from Match 1st to Match 5th, seedlings are transplanted before April 5th when the seedlings have six leaves and the broomcorn is harvest during a period from July 10th and July 15th in the same year; and regenerated broom corn seedling are subjected to water drainage for preventing waterlogging, moisture preservation and seedling raising, tiller removal and weeding and fertilizer application and hilling and harvested for the second time during a period from October 10th and October 20th in the same year. The method makes full use of the regenerative capacity of broomcorn and light and heat resources in late autumn, improves land multiple cropping index and economic benefits, advances sowing and planting of the first broomcorn, draws on the advantages and avoids disadvantages, and increases the yield of regenerative broomcorn. The technique can achieve grain yield of 989 kilograms per mu and output value of 2,187.75. And the technique realizes an increase of 239 kilograms in grain production and an increase of 942.75 Yuan in income per mu compared with the prior planting technique for wheat, corn and teocoma grandiflora.

Description

Technical field [0001] The invention relates to a method for planting crops, which is suitable for application in shallow hilly areas of Pingba, where the altitude is below 450 meters, the average temperature in March and October is above 15 degrees, and the average temperature in September is above 20 degrees, especially suitable for popularization and use in rural dry land in southern Sichuan. Background technique [0002] In the rural areas of southern Sichuan, the mode of dryland planting has always been the interplanting mode of wheat, corn, and sweet potato. The specific manifestation is that the above three crops are planted together, and the grain yield per mu is 750 kg, including 150 kg / mu of wheat and 450 kg / mu of corn. , red sweet potato is 150 kg / mu (dry yield), according to the market price (2007 wheat 1.50 yuan / kg, corn 1.60 yuan / kg, sweet potato 2.00 yuan / kg), the output value per mu is only 1245 yuan, such an output level is wasted Land and human resources, t...
