膜上覆土栽培对云南春作马铃薯生长、产量及品质的影响
The Effects of Growth, Yield and Quality of Potato with Covering Soil on the Plastic Film Cultivation in Spring Cropping of Yunnan
摘要
Abstract
[Purpose] To explore the effects of growth,yield and quality of potato with covering soil on the plastic film cultivation in spring cropping of Yunnan,screening the best cultivation pattern for spring cropping potato in Yunnan.[Method] Qingshu9,a mainly cultivated variety in Yunnan,was used as the tested material and the randomized complete block design was taken.We designed the different thickness plastic film and soil on the plastic film and conducted the experiment under combination factor experimental design.Soil temperature and water contents emergence,plant growth,yield and quality were measured.[Result] The covered soil on the film enhanced its drought resistance,kept the soil moisture,balanced soil water content,at the same time,it also appropriately restrained effect of increasing temperature.So that,potato seeds didn't emerge,the treatment of 0.008 mm hyaline film and add a thickness of 4 cm soil on film manifested a highest emergence ratio and fastest speed of emergence,which all the experiments were conducted under covering plastic film but completely without soil on the film condition.The treatments of covering soil on the plastic film universally could manifest emergence ratios significantly higher than the check;effectively promote the emergence,increase the speed of emergence,heighten its height,expand its stem diameter,increase the amount of branches,extend the growth period,the longest extended the 14 days,and then promote production per plant,the treatment of 0.008 mm hyaline film and add a thickness of 4 cm soil on film manifested a manifested the highest production,and improve dry matter,total starch,protein and nitrogen content of potato tuber.What's more,cover soil on the plastic film can reduce the labor of breaking film,it is convenient to harvest.[Conclusion] Cover soil on the plastic film is a kind of high-yield and efficient cultivation pattern.Among them,the treatment of 0.008 mm hyaline film and add a thickness of 4-6 cm soil on film manifested the best result.关键词
