Eight Methods of Pearl Sorghum Cultivation

1. Site preparation: One plow and one plow for rehabilitated land, two plows and two plows for wasteland (birth place), and pounding the pounds of earth to meet the requirements for planting corn. Paddy fields or plots with excessive moisture should not be planted. 2, Shizujifei: In the entire good ground, apply 20 kg compound fertilizer per 667 square meters in the interline, cover with soil; where conditions permit, put 2000 kg of organic fertilizer. 3. Seeding: The temperature can be sown when the temperature is stable at 15 degrees. It can be planted in Guangxi from February 15th to August 20th. Seeds are planted at 6000-7000 holes per 667 square meters. The row spacing is 2 050 cm, and 3 seeds per hole are planted. 667 square meters with 750 grams. Soak seeds in warm water for 10 hours before sowing so that the letters can be neat and tidy. The sowing depth is 2 to 3 cm. If the cover soil is too deep, the seedling time is prolonged, which affects the management of the harvest. 4. Field management: Prevent drought before emergence. When the seedlings grow to the leaves, they will be seedlings, and each seedling will keep 1 strong seedling, ensuring that there are 6000-7000 strains per 667 square meters. After setting the seedlings, apply 8 kg to 10 kg of urea per 667 square meters of topdressing and cultivate the soil. 5. Pest Control: Pearl sorghum diseases mainly include sorghum bacterial streak disease and penicillium gentianus. Sorghum bacterial streak disease occurs at the seedling stage, penicillium disease occurs at the heading stage, and can be controlled by spraying with carbendazim or zeinzin. The pests mainly include aphids, Spodoptera litura, aphids, and scarabs. Aphids and beetles occur at seedling stage; Spodoptera litura and aphids are at risk during heading and wax ripening stages, and they can be sprayed with insecticidal double and fast spirits. The sorghum is very sensitive to organophosphorus pesticides and cannot be used. During the growth period, it is also very sensitive to pesticides such as trichlorfon, dichlorvos, safrole, and dimethoate. It is also sensitive to pesticides such as phosphoamine, phoxim, and methamidophos and cannot be used. According to the law of occurrence of pests and diseases, strictly according to the instructions of the pesticide formulation, correctly grasp, appropriate application, and active prevention. 6. Harvesting: Planting in Guangxi, the growing period can reach 95-120 days for harvesting, and the tight spike-type can be harvested earlier than the scattered ear-type. Sunny harvest should be selected for sun drying. 7, regeneration of cultivation: long frost-free period, the accumulated temperature, can engage in renewable cultivation. The pearl sorghum buds have a strong germination ability. After harvesting or tasselling, the axillary buds in the dormant state of the stem base will germinate quickly, grow new plants, and develop under suitable conditions. Season or season. Every 667 square meters of production up to 300 to 400 kg. Need to stay in the rebirth of pearl sorghum for 15 days before ripening need to re-apply 10 kg of whole fertilizer, mature after harvest in time, with the cut with the cut. Chopping stalks after harvest should not be too high, so as not to consume nutrients, leaving 2 or 3 axillary buds exposed on the ground. Leave 2 to 3 strong buds after sprouting. Regenerative stilts should pay attention to adding fertilizer to topdressing. Apply 10 kg compound fertilizer per 667 square meters. 8. Seed conservation methods: Semi-compact spike type should be selected for seed retention, and tight ear type and scattered ear type should not be preserved. Because, tight spike type grains are susceptible to mildew and spleen, the yield of loose spike type is not high.
