1984年采取统一设计在43个点进行了地膜育秧试验,同时在四个地市示范286.9万亩。结果表明,地膜育秧具有温室育秧能保证适时播种,防止烂秧,培育壮苗,提早抽穗的同等效能,其产量相近;且节能、成本低,经济效益高;育秧方法简便,技术易于掌握,适于承包责任制。多点试验结果如下: 1.到达1.5叶的天数:温室育秧为6.94天,地膜育秧为9.22天; 2.成秧率:温室育秧为91.83%,地膜育秧为88.29%; 3.齐穗期:温室秧比地膜秧提早0.3～0.7天; 4.亩产量:温室秧为1,109.01斤,地膜秧为1,115.20斤; 5.经济效益:温室秧每斤种子育秧费为1.37元,地膜秧为0.39元。示范区共 节约煤炭2.54万吨,减少育秧费622.42万元,节约地方开支8.9万元。
In 1984, a uniform design was used to test the plastic film seedling cultivation at 43 spots, while a demonstration area of 2,869,000 mu was established in four cities and prefectures. The results showed that the plastic film seedlings with greenhouse seedling can ensure timely sowing, prevent rotting seedlings, nurturing strong seedlings, early heading equivalent performance, and its yield is similar; and energy saving, low cost, high economic efficiency; seedling raising method is simple, technology is easy to master, suitable In the contract responsibility system. Multi-point test results are as follows: 1. The number of days to reach 1.5 leaves: 6.94 days in the greenhouse seedlings, seedlings 9.22 days; 2. Seedling planting rate: 91.83% in greenhouse greenhouse seedlings, 88.29% Greenhouse seedling than plastic film seedling 0.3 to 0.7 days earlier; 4. Mu yield: greenhouse seedlings 1,109.01 pounds, mulching 1,115.20 pounds; 5. Economic benefits: greenhouse seedlings per kilogram of seedling fee is 1.37 yuan, mulching seedlings 0.39 yuan. Demonstration area a total of 25,400 tons of coal to save, reduce seedling fee 6,242,200 yuan, saving 89,000 yuan local costs.
