我县从1976年开始搞早稻温室育秧,以“原丰早”为当家品种,取得良好成效,惟有迟熟现象。为此,81年起将几个早稻品种进行比较试验。二年来,初步筛选出生长期短、成熟较早、抗性较强、产量较高的“繁一”、“广晓早”、“澄溪早”三个品种。 (一)材料与方法:82年将初选出的“繁一”、“澄溪早”、“广晓早”三个品种,以“原丰早”为对照,进行比较栽培。小区面积0.0667亩,随机排列,三个重复。同于4月26日播种,5月27日移栽。用60×24cm秧盘,薄土育秧。每盘播干谷100～110克,每亩播量为1000斤,播后四天露天寄秧。株行距3×
My county started from 1976 to cultivate early rice greenhouse, “original abundance of early” as the original varieties, achieved good results, only late maturing phenomenon. For this reason, several early rice varieties have been comparatively tested since 1981. In the past two years, three breeds of “Fan Yi”, “Guang Xiao Zao” and “Cheng Xi Zao” with short growing period, earlier maturity, stronger resistance and higher yield were initially screened. (I) Materials and Methods: The three varieties of “Fan Yi”, “Cheng Xi Zao” and “Guang Xiao Zao” which will be primaries in 82 years will be compared and cultivated according to “Yuan Feng Zao”. Residential area of 0.0667 acres, arranged randomly, three repeated. The same sown on April 26, May 27 transplanting. With 60 × 24cm seedling tray, thin soil Yu Yang. Drying every dish 100 ~ 110 grams per pantry, sowing rate of 1000 pounds, four days after sowing seedlings. Plant spacing 3 ×
