我们在总结水稻温室无土育小苗的基础上,经过一些改进,培育出了中苗。我们用新稻68—11温室培育9天,苗高达到13.2厘米,可见叶4片,5月13日移栽在多年荒废的盐碱地共36亩,获得了亩产720斤的好收成。其中13亩高产试验田亩产达910斤。现将我们在水稻温室育中苗中的一些改进措施介绍如下: 一、降低播量。我们使用的秧盘面积为3,200平方厘米,往年每盘播种稻芽1.5斤,折合每亩播种干稻2,500斤;去年每盘播种稻芽1斤,折每亩播干稻1,686斤。二、扩大层距。原温室设计秧盘层距为6寸,共8层,改为层距8寸,6层秧盘,改善了秧苗的光
On the basis of summing up the soilless seedlings in rice greenhouse, after some improvements, we nurtured the middle seedlings. We use the new rice cultivating 68-11 greenhouse for 9 days, the height of 13.2 cm, the visible leaves 4, May 13 transplanting in a number of abandoned saline land for a total of 36 acres, access to a good yield of 720 pounds per mu. Among them, 13 mu of high-yielding trial plots yield 910 kg per mu. Now we introduce some improvements in rice greenhouse seedlings in the introduction as follows: First, reduce the sowing. The area of seedlings we used was 3,200 square centimeters. In previous years, 1.5 kilograms of rice buds were sown per dish, equivalent to 2,500 kg of dry rice per acre. Last year, 1 kg of rice seeds were sown per dish, and 1,686 kg of dry rice per acre was folded. Second, to expand the layer distance. Original greenhouse design seedling tray spacing of 6 inches, a total of 8 layers, replaced by layer spacing 8 inches, 6 layer tray, improve the light seedlings
