1.水稻稀植栽培有什么好处?水稻合理稀植可以减少用种量.我省稻区当前主要推广9×4寸和9×5寸的栽培形式,每亩插秧1.66万穴和1.33万穴,分别比9×3寸的栽培形式减少0.56万穴和0.89万穴;9×6寸的每亩插1.11万穴,比9×3寸的减少1.11万穴.插秧的穴数减少了,育苗面积、用种量也相应减少.原来每亩本田需秧苗15—20平方米,实行稀播后可减少到7—10平方米,用种量减少2—4公斤.每亩本田的育苗成本可以节省10—20元.由于育苗面积减少,用苗量降低,铲秧、运苗、插秧等各项农活的用工量相应减少,同时加快了插秧进度,有利于争取农时.水稻稀植栽培,可以改善植株的通风
1. What is the benefit of rice sparse cultivation? Rice reasonable planting can reduce the amount of planting. My province rice mainly to promote the current 9 × 4-inch and 9 × 5-inch cultivation forms, transplanting 16,600 acre per acre and 13300 acre , Respectively, than the 9 × 3-inch cultivation form to reduce 0.56 million and 08,800; 9 × 6-inch per mu inserted 11,100 points, compared with 9 × 3-inch reduction of 11,100 points. Transplanting reduced the number of nursery Area, with the corresponding reduction in the amount of the original Honda seedlings per acre to be 15-20 square meters, the implementation of thinning can be reduced to 7-10 square meters, with a reduction of 2-4 kg of seedlings per mu Honda cost of seedling can Save 10-20 yuan.As a result of reduced nursery area, reduce the amount of seedlings, shovel seedlings, seedlings, transplanting and other farm work correspondingly reduced the amount of labor, while accelerating the planting progress, is conducive to farming time. Improve plant ventilation
