我场去年进行了用锯末子做红松育苗覆盖物的试验。试验区覆2厘米厚的锯末子,对照区覆2厘米厚的沙土混合物(沙土比例为1:1),其他作业相同。试验结果:试验区幼苗可提前7～10天出土,而且出得齐、色泽正、抗病力强、保苗率高。每平方米产苗量,试验区为973株,对照区只有595株,比对照区提高63%。 Last year, I conducted a test of kiwifruit seedling coverings with sawdust. The test area covered with 2 cm thick sawdust, control area covered with 2 cm thick sand mixture (sand ratio of 1: 1), the same as other operations. Test results: The test area seedlings can be excavated 7 to 10 days in advance, but also out Qi, color is positive, disease resistance, seedling rate. The yield per square meter was 973 in the experimental area and 595 in the control area, which was 63% higher than the control area.
