为适应杂交水稻的迅速发展,必须对传统的育秧技术进行改革。为摸索地膜育秧在川东长江河谷地区的推广价值,我们对此进行了试验,现将结果报告于后。我们采用杂交水稻“珍圭”作材料,3月18日播种,分地膜两段多蘖秧、地膜一段多蘖秧、温室两段多蘖秧三种育秧方式;地膜和温室两段秧按每平方尺0.15斤,地膜一段秧按每亩10斤和20斤的用种量播种;地膜育秧全部搭拱,拱高5寸;地膜和温室两段 In order to adapt to the rapid development of hybrid rice, we must reform the traditional seedling technology. To explore the promotion of plastic film seedlings in the Yangtze River valley in eastern Sichuan, we conducted a test, the results are reported later. We use the hybrid rice “Jane Kyu” as material, sowing on March 18, sub-film two more tiller seedling, mulching more tiller seedlings, greenhouse two multi-tiller seedlings three seedlings; plastic film and greenhouse two seedlings per 0.15 square feet per square foot, a section of plastic film seedlings per acre 10 kg and 20 kg sown with seeds; plastic film seedlings all arch, arch 5 inches; mulching and greenhouse two
