Rehabilitation Sorghum planting techniques
Based on years of experiments, the Longchang County Bureau of Agriculture has launched a new regenerative sorghum planting technology this year. After harvesting sorghum in spring, it uses dormant buds of the stem nodes to germinate and grow into a panicle, which can effectively use autumn temperatures and sunlight. And valuable land resources, further tap the sorghum production potential, effectively promote farmers to increase income. The suitable sowing date for regenerated sorghum is at the end of March, and the method of raising seedlings is similar to that of corn. Bed soil fertilization and thinning seedlings can be used to cultivate seedlings. Fertilizer seedlings can also be used to cultivate seedlings after seedling emergence. Transplanting and specifications: The sorghum seedling age is about 25 days. When the leaf age is 4 to 5, it can be transplanted with soil. After transplanting, it is necessary to pay attention to the control of underground pests. Reserve land for planting more than 6,000 plants per acre. Fertilization: The base fertilizer is 1000 kg per mu, and the ammonium bicarbonate is 15 kg to 20 thousand years old. The plant ash is 200 years old. The superphosphate is 35 to 40 years old and the feces water is 30 to 40. About 10 days after transplanting, 10 kg of ammonium bicarbonate per acre was used to raise seedlings. After the jointing, reuse urea 10 kilograms or ammonium bicarbonate 20 kilograms to reapply jointing and booting fertilizer. The management of spring sowing sorghum after harvest is the key to the regeneration of sorghum high yield. To timely and adequately apply budding fertilizer, 10 to 15 days before the spring sowing of the sorghum harvest, we should see that when 80% of the main beams in a plot have matured, we must apply a budding fertilizer once per mu. Urine 8 eternal to 10 thousand antiquities 30 pick to 40 pick splash. The spring sow sorghum sorghum hardens in the upper central grain, and the lower grain can be harvested when it has a slight juice. When harvesting, pay attention to keep the piles 3 cm to 4 cm high, and pay attention to protecting the remaining sorghum piles during and after harvest to facilitate the growth of regenerated seedlings. When the regenerating seedlings grow to three leaves, only one to two plants are underneath the base of each sorghum pile, and all excess and regeneration seedlings are wiped off. Strengthen jurisdiction. Application of joint fertilizer, in mid-August, 8 acres of urea per acre to 10 thousand antiquities 30 pick to pick 40, reapply jointing booting fertilizer. Diseases and insect pests are severely affected by the early and late stages of flowering and maturation of regenerated sorghum. Therefore, after the first heading flowering, we must first use the medicine to prevent and control. In the middle and later period, the heading should be treated separately after the flowering. The total prevention and treatment is 3 times to 4 times.
