一、培育出适合机插的标准化秧块(一)育秧前的准备1、备足备好营养土。育秧前每667m2大田备足100kg的过筛营养细土,另备足未培肥的过筛细土25kg作盖籽土。营养土选择熟化的土壤,采用有机肥和无机肥相结合的方法进行培肥,在冬前结合耕耙对取土田块每667m2匀施腐熟的人畜粪2000kg。取土时结合耕耙每667m2匀施35％的氮、磷、钾复合肥50kg,而后取走15□厚的表土覆膜遮雨、升温堆闷20天,播种前三天过筛
First, to cultivate a suitable machine plug standardized seedlings (A) preparation before seedling 1, ready nutrition soil. Seedlings planted before the bricks per 667m2 100kg sieve nutrition fine soil, and the other not enough fertilizer sieved fine soil 25kg cover cover soil. Nutrient soil selection of mature soil, the use of organic manure and inorganic fertilizers combined with the method of fertilizing, combined with harrow in winter before harvesting block every 667m2 well-manure livestock manure 2000kg. 50 kg of nitrogen, phosphorus and potassium compound fertilizers are evenly applied to each 667m2 of soil when taking soil, and then 15cm thick topsoil is removed for rainy day, the temperature of the pile is mined for 20 days and sifted three days before sowing
