不同覆盖措施对土壤性质及辣木产量的影响
The Effects of Different Coverage Measures on Soil Properties and the Yield of Moringa oleifera
摘要
Abstract
[Objective]To study the effects of different coverage measures on soil properties and the yeild of Moringa oleifera.[Method]We car-ried out the test of different coverage measures(black film mulching T1,white film mulching T2,straw mulching T3,control CK)on soil properties and the yeild of M.oleifera in Ruili suburb,Yunnan Province from 2016 to 2017.[Result]The overall preservation effect order of soil moisture un-der different coverage measures was T1,T2,T3,CK.In the dry season,plastic mulching played an important role in water conservation while it's effect was lower than that of straw mulching and plowing in the rainy season.The white film's warming effect was the most significant of all.The soil temperature between 20 cm and 40 cm were higher than that with other coverage measures.The effect of black film mulching had significant seasonal variation and the warming effect varies with the soil thickness.Coverage measures can improve the contents of total nitrogen,alkali nitro-gen,total phosphorus,available phosphorus and available potassium in soil.And there was a significant difference between white plastic film mulc-hing and other contrast tests.Coverage measures can promote the decomposition of organic fertilizer and the organic matter will be absorbed and used more quickly.The yield order of M.oleifera leaves under different coverages was T2,T1,T3,CK.[Conclusion]The white plastic film mulching has a very high value of promoting and using in the wide scale cultivation of M.oleifera.关键词
