更新传统种植观念,实施良种良法,科学管理,是实现农作物高产高效的关键。去年,安徽省灵壁县农民程亚,从山东单县农技应用研究所引种“兴农2号”大豆良种,春播0.5亩。他按照技术要求,精细整地播种,施磷肥25公斤,氯化钾10公斤,尿素12公斤,圈肥1立方,采用穴播,行距70厘米,穴距28厘米左右,亩持苗量1万株。株高20厘米时,喷植物动力P2003微肥一次,株高80厘米,喷多效唑一次,整个生育期没浇水,最终株高1.50米,平均单株结荚82个。9月上旬收割,实收大豆204.5公斤,折合亩产409公斤。收麦后,6月14日他又机播同一品种夏大豆3亩,大行60厘米,小行40厘米,亩持苗量1.3万株,株高20厘米时喷P2003一次,亩追施氮、磷、钾复合肥(各含15%)40公斤,整个生育期共浇两次水,生长良好,最终株高1.30米,平均单株结荚63个,9月22日收割,3亩实
Renewing the traditional concept of planting, the implementation of good seed law, scientific management, is the key to achieving high yield and high efficiency of crops. Last year, Cheng Ya, an agronomist from Ling County in Anhui Province, introduced “Xinnong No.2” soybean seed from the Shannian Institute of Applied Agricultural Technology in Shandong Province and sowed 0.5 mu in spring. According to the technical requirements, he sowed the fine sowing land with 25 kg of phosphate fertilizer, 10 kg of potassium chloride, 12 kg of urea and 1 cubic meter of lap fertilizer. The planting distance was 70 cm and the distance between the holes was 28 cm. Plant height of 20 cm, spray plant dynamics P2003 fertilizer once, plant height 80 cm, spray Paclobutrazol once, the entire growth period without watering, the final plant height of 1.50 meters, an average of 82 pods per plant. In early September harvest, harvest soybean 204.5 kg, equivalent to 409 kg per mu. After receiving the wheat, he also sowed the same species of summer soybean 3 acres on June 14, a large line of 60 cm, a small line of 40 cm, Miao holding seedlings 13,000, plant height of 20 cm when spraying P2003, acre nitrogen , Phosphorus and potassium compound fertilizer (each containing 15%) 40 kg, the entire growing period of water twice a total of two well-growing, the final plant height of 1.30 meters, an average of 63 pods per plant, September 22 harvest,
