在水稻工厂化育秧中,吉林省农科院提出利用钙塑纸制成一定规格的衬套,以硬塑秧盘作母盘,把衬套材在母盘里播种,寄秧时把母盘脱掉,再重装衬套,播种,如此循环使用。以衬套代替秧盘,是减少投资、降低成本的一条有效途径。今年我们对钙塑纸衬套脱盘育秧进行了初步试验。现将试验情况介绍如下: 一、试验概况 1982年2月中旬,在上海县莘庄公社明星大队试点,用闸北木材厂生产的钙塑纸(含碳酸钙50％,低压聚乙烯50％),制成1.5×
In the rice plant breeding seedlings, Jilin Academy of Agricultural Sciences put forward the use of calcium-plastic paper made of a certain specification bush to hard plastic seedling tray as a master, the lining material in the master planted seedlings when the master tray Take off, and then reinstall the bush, sowing, so recycle. To bush instead of seedlings, is to reduce investment and reduce costs an effective way. This year we carried out a preliminary test of Cassia paper bushing off the tray seedling. Now the test situation is described as follows: First, the test profile In mid-February 1982, in Xinzhuang commune, Shanghai Star brigade pilot, with Zhabei wood plant production of calcium plastic paper (containing 50% of calcium carbonate, low pressure polyethylene 50%), Into 1.5 ×
