本文研究了用化学试剂处理草地早熟禾种子的发芽效果及其在温室条件下工厂化建植草皮的技术。结果表明,与未用化学试剂处理的种子相比,3种试剂4个处理中以0.5%氢氧化钠处理效果最好,不权能提前2~3天发芽出苗,而且能使出苗率由原来的49.3%提高到86.3%;在温室条件下建植草皮.种床质地很重要,土与锯木混合,两种体积比处理中以2:1效果好,出苗均匀而迅速;根层中铺设塑料薄膜与否,对建植草皮影响不大,不过铺设薄膜便于草皮搬运和铺植,但要注意适时移植,否则因薄膜妨碍根下伸而影响生长。
In this paper, we studied the germination of the seeds of Poa pratensis using chemical reagents and the technology of factory-built turf in the greenhouse. The results showed that compared with the seeds without chemical treatment, the treatment with 0.5% sodium hydroxide was the best in the four treatments of the three agents, and did not have the ability to germinate and emerge 2 to 3 days in advance, and the seedling emergence rate was improved from The original 49.3% to 86.3%; turf built under greenhouse conditions. The quality of the seedbed is very important, soil and sawdust mixed, the two volume ratio treatment with 2: 1 effect is good, uniform and rapid emergence; laying of plastic film in the root layer or not, the establishment of turf has little effect, but the laying of film Easy turf handling and planting, but should pay attention to timely transplantation, or because of the film hindered root extension and affect growth.
