为了探索水稻杂种栽培技术,以夺取高产,今年我们做了密度、施肥、灌水等项试验,现小结如下: 一密度试验 1、处理。不同基本苗:用珍汕九七A×泰引一号,1苗、2苗、3苗、4苗、5苗五个处理,每小区面积0.1么,设两次重复,密度5×8寸,4月17日播种,5月4日插秧,7月28日始穗,8月30日成熟,9月1日收割。不同密度:用同一组合,5×7寸、5×8寸、5×(5+10)/2寸、5×10寸、10×15寸、4×6寸,六个处理,小区面积0.1么,设两次重复,插二苗,4月17日播种,5月4日插秧,7月28日始穗,8月30日成熟,9月1日收割。
In order to explore hybrid rice cultivation techniques to capture high yield, this year we have done a density, fertilization, irrigation and other tests are summarized as follows: a density test 1, treatment. Different basic seedlings: Treated with Zhenshan 97 × A × Taiyin No. 1, 1 seedling, 2 seedlings, 3 seedlings, 4 seedlings and 5 seedlings. Each area has a density of 0.1 ×. Repeat for two times with a density of 5 × 8 inches , Sown on April 17, transplanted on May 4, spikelets on July 28, ripe on August 30, and harvested on September 1. Different density: the same combination of 5 × 7 inch, 5 × 8 inch, 5 × (5 + 10) / 2 inch, 5 × 10 inch, 10 × 15 inch, 4 × 6 inch, six treatment, cell area 0.1 Mody, set up two repeat, insert two Miao, sowing on April 17, May 4 planting, beginning on July 28 ear, August 30 mature, September 1 harvest.
