At present, it is during the period of transplanting sorghum in southern Sichuan. Zhang Guanghong, director of the agricultural technology station of the Agricultural Bureau of Jiangyang District of Ganzhou City, reminded farmers and transplanted sorghum that the key was selecting strong seedlings, followed by rational close planting.
In view of the soil structure in the south of Sichuan, at present, the conventional varieties that are better in production include Qingchaoyang sorghum, Qingchao No. 2 and Qingchuang No. 5, and the hybrids include No. 3, No. 4 and No. 6 Wait. Scientific transplanting is a key link in ensuring the output of sorghum and directly affects the income of farmers. In terms of soil quality in the south of Sichuan, it should be properly planted and fertilizer should be formulated. Transplanting planting methods, net work can be. The hybrid sorghum 6 leaves were transplanted, and the conventional sorghum was transplanted after raining before the 9-leaf stage. Interplanting generally about 5000 acres of planting, net for conventional species of 2000 ~ 8000 strains, hybrids are rare. The pattern is 2 feet 0.5 feet (single plant) or (1+3) feet 0.8 feet (two plants).
High fertilization. Organic fertilizers should be promoted with inorganic fertilizers or nitrogen, phosphorus, and potassium. The average medium soil fertility block can apply 8kg to 10kg of pure nitrogen, 30kg to 40kg of superphosphate, and 2000kg to 3000kg of manure water per acre. Fertilization method with heavy bottom early recovery, replanting booting fertilizer.
Check the seedlings in time to make up for deficiencies, and after transplanting to survive, combine fertilization for cultivating, and then combine ploughing and fertilizer for cultivating soil before jointing.
