- The effect is obvious on weed control with black film mulched,the fresh weight of weed in field is reduced 70. 利用黑色地膜覆盖防草效果明显,田间杂草鲜重比与黑膜同材质的透明地膜覆盖减少70。
- The increasing in grain yield was about 10.3%, 8.9%, 23.2%respectively as compared with the plastic film mulch, the straw mulch and the unmulched cultivatiom. 稻谷产量较地膜覆盖、秸秆覆盖、露地旱作栽培分别增产10.;3%25;8

- However, no significant difference was found as to the uptake and distribution of Fe in potato with film mulch and potash fertilizer. 钾肥在成熟期之前的一段时间内能在一定程度增大铁在块茎中的分布,但是此二因素对马铃薯体内铁的影响作用均未达到一定的显著水平。

- Therefore,the yield product was markedly increased by using salt-tolerant wheat cultivar and plastic film mulching cultivation in saline soils. 利用耐盐小麦品种进行覆膜穴播显著提高盐碱地小麦产量。
- Film mulch decreased Fe distribution in the leave of potato and increased that in the stem and tuber, and thus increased Fe uptake and accumulation in the tuber. 而铁素在马铃薯体内的分布情况表现为:前4个时期在各个器官中分布的顺序为叶>茎>块茎,到成熟期表现为茎>叶>块茎。
