在逐步扩大三熟制面积和多种迟熟高产品种的情况下,收种季节矛盾更为突出。为解决矛盾,我们在认真总结大、小苗育秧经验和学习外地经验的基础上,进行了“三秧”配套试验。据4个小区(1.44亩)试验结果,平均亩产838斤,比对照(水育大秧)区增产6.8%,其中最高的0.32亩,折亩产925斤,比对照增产21.3%。“三秧”,就是前期育小苗,中期搞抛苗,后期从抛苗田中拔出,象大秧一样插到大田。去年供试品种“农虎6号”,种子经过消毒催芽,6月25日播在草子留种田,秧板阔4.4尺,沟6寸,秧板做平后,上浇水河泥,播后塌谷,秧田管理同普通田。除草治虫各两次,7月19日
In the case of gradually expanding the area of three-cropping system and a large number of late-maturing and high-yielding varieties, the contradiction in the planting season is even more prominent. In order to solve the contradiction, on the basis of earnestly summing up the experiences of large and small seedling raising seedlings and learning foreign experiences, we carried out the supporting experiment of “Sanyang”. According to the test results of 4 plots (1.44 mu), the average mu yield was 838 kg, an increase of 6.8% over the control (Shuidai Dayanying) area, with the highest of 0.32 mu and 925 kg of mu yielding 21.3% more yield than that of the control plot. “Sanyang”, is the pre-nursery seedlings, mid-term to throwing Miaomiao, the latter from the cast Miao Tian pulled out, like the big seedlings inserted into the field. Last year tested the varieties of “Nonghu 6”, the seeds after disinfection and germination, June 25 sowing in the grass to stay farming, seedlings width of 4.4 feet, 6-inch ditch, seedlings to do after the flat, watering the river mud, sowing Fall Valley, seedling management with ordinary fields.
