Speaking of sweet sorghum, I believe that many farmers' friends are common, and when I was a child, I was estimated to have chewed and eaten. When I was young, I was eating sweet sorghum because I didn’t grow sugar cane at home. In fact, this sweet sorghum is relatively simple to plant, today Xiaobian will introduce you to its cultivation method!
First, how sweet sorghum planting?
1. Site selection: The roots of sweet sorghum are well-developed with strong water absorption and fertility. It is suitable for the selection of flat, loose and fertile plots. The requirements for the front hoe are not strict, and corn glutinous rice and soybean glutinous rice can be used. However, it is necessary to make fine grounding before planting, and to flatten the ground.
2, selection of seed drying: sweet sorghum before sowing for wind selection or screening, elimination of small grains, glutinous grains, diseased grains, select large seeds, full of seeds for production. At the same time, choose a fine weather, soak the seeds for 2 to 3 days, and increase the seed bud potential and bud rate.
3, pesticide dressing: sweet sorghum before the sowing seed dressing can be selected with high-quality seed coating seed dressing, control smut, seedling disease, deficiency and underground pests, etc., can also use 25% powder rust WP can be used as seeds The amount of 0.3 to 0.5% seed dressing.
4. Sowing time: The sowing date of sweet sorghum is determined according to the growth period, soil temperature and soil moisture. Generally, the ground temperature of 5 cm is stable at 10-12 °C, and the soil water content is 15-20%. Late-maturing varieties are broadcast early and early, and early-maturing varieties are broadcast in due course.
5. Seeding density: The sowing density of sweet sorghum is based on the principle of “fat and dense, thin and thinâ€, usually 65~70 cm ridge, double row and equal row in ridge, and the general seeding amount of dwarf cult is 15~22.5 kg. /ha.
6. Seeding depth: The sowing depth of sweet sorghum is 3~4.5 cm, but the soiling of different soil types should be flexibly mastered. The clay should be compact and easy to be compacted. The sand land can be properly spread.
Second, sweet sorghum planting management:
1, Miao Ding Miao: sweet sorghum seedlings 3 to 4 leaves period seedlings, 5 ~ 6 leaf stage fixed seedlings, set seedlings to be equidistant seedlings, stay strong seedlings, positive seedlings, do not leave double seedlings, two seedlings, It is also necessary to remove the hybrids, increase the purity, and fully exert the yield-increasing effect of the improved varieties.
2, cultivating management: sweet sorghum seedlings cultivating 2 to 3 times, the first combination of fixed seedlings, 10 to 15 days after the second, a cultivating before and after jointing, combined with topdressing, soil, promote fertility while enhancing wind , anti-fall and soil water storage capacity.
3. Timely irrigation: the water requirement for sweet sorghum seedlings accounts for about 10% of the total water requirement during the whole growth period, 50% for the jointing and booting period, 15% for the booting to flowering period, 20% for the filling period, and 5% for the mature period. It should be properly watered at the jointing booting stage, flowering stage and filling stage.
4, rational fertilization
(1) When planting sweet sorghum, it is necessary to combine the soil preparation with the base fertilizer, and the seed fertilizer is mainly phosphate fertilizer. It can apply 35% special compound fertilizer 30~35 kg/mu, and apply organic fertilizer 1500-2000 kg.
(2) After the emergence of sweet sorghum, the seedling fertilizer can be applied according to the emergence condition, and the jointing period can generally be applied to 1000 kg of agro-fertilizer per acre, and urea is 10 to 15 kg per acre.
(3) Sweet sorghum can produce 1000 kg/mu of fertilizer and 20 kg/mu of urea at the booting stage.
(4) Sweet sorghum can be applied with 1000 kg/mu of fertilizer and urea, and urea is 8-10 kg/mu.
(5) Sweet sorghum heading to the filling stage, apply appropriate amount of potassium dihydrogen phosphate to promote early maturity and increase yield.
Ok, the above is the simple planting method for sweet sorghum that I want to share with you today. I hope I can help you friends!
