| 摘 要： | 草莓在粗质风沙化土地上栽培时, 如何保证草莓所需水分、养分的供给是一个重要且难解决的问题。经过试验研究, 采用保水间层栽培能解决这一关键问题。在栽植区土壤中铺设保水间层或覆盖地膜均能提高植株成活率, 提早1周左右产果, 大幅度增加产量, 取得明显经济效益。在草莓栽植区30cm深处铺设高20cm的保水间层, 可增产134.4kg/亩, 获得201.6元净经济收入。保水间层与覆盖地膜结合使用, 则净增产291.6kg/亩(130.7%), 获638.4元纯收入, 相当于当地农民人均年收入.增产原因是土填含水量(生长期内)始终保持在最适宜草莓需要的范围内, 且可防止养分淋溶损失。

| Abstract: | According to the tests, water-holding film at a certain depth below the surface and covering the surf see with nun film of the planting plot can raise the taking root ratio, inccease soil moisture content, move up one week to harvest, significantly increase the yield and get great economical profit.Burying water-holding film at 30 cm soil depth of the planting plot (the height of the bag is 20cm) can increase yield 134. 4 kg per mu, and obtain 201. 6 yuan net economical profit per mu. A combination of this two techniques increased the yield to 291. 6 kg per mu (130. 7% ),obtaining net econmical profit of 638. 4 yuan per mu. It equals the average annual income of farmers in JiangxiProvince.The water-holding film cultivation technique is for strawberry cultivation in coarse sand land. |
