苏家屯区农林局合理密植是夺取水稻高产的中心环节。要根据品种特性、土壤肥力、施肥水平、管理技术等条件因地制宜地确定密度。以丰锦品种为例,据调查千斤以上的地块,一般每亩有效穗数在30～35万之间,平均每穗实粒60～70之间。根据其品种特性,适当缩垄增行是适宜的,平肥地以10×3寸,每穴5～6苗;土质瘠薄,利用山水、井水灌溉的,以穴保产,以9×3寸为好,每穴7～8苗;少数污水高肥地块,可适当稀些,防止“一刀齐”。
Sujiatun Agriculture and Forestry Bureau reasonable close planting is to win the center of high yield of rice. According to the characteristics of varieties, soil fertility, fertilization levels, management techniques and other conditions to determine the density of local conditions. To Feng Jin varieties, for example, according to the survey more than pounds of plots, the general number of panicles per acre between 30 to 350,000, the average grain per spike 60 to 70 between. According to its variety characteristics, proper sowing growth is appropriate, flat and fat to 10 × 3 inch, per hole 5 to 6 seedlings; soil infertility, the use of landscapes, well water irrigation, to the hole Paul yield to 9 × 3 Inch is good, 7 ~ 8 seedlings per hole; a few high-fertile land, may be appropriate to dilute, to prevent “knives together.”
