作物间套作种植方式间作效应研究

Research of Intercropping Benefit of Crop Intercropping Systems

阐述了国内外作物间套作方式的研究进展及内容,总结近五年来作物间套作方式的研究特点:土壤容重、光照强度、叶绿素含量、抗病虫性、土壤水分变化规律、施肥水平对间套作作物性状的影响和经济效益方面研究较多;间套作水土保持作用,土壤水分和养分利用状况及作物地下部分等方面研究较少。提出间套作在栽培措施方面应注意的关键问题:合理安排间套作作物的播种期和移栽期;采用共生系统施肥法(即施肥时要同时考虑间套作作物);种植密度要适宜。

The research progress and content on planting patterns of intercropping crop at home anti m the world were＂ stated. Sceondly, the characters of planting patterns on intercropping crop were summarized about five years.They are researched much that soil bulk density, illumination intensity, chlorophhll content, resist of diseases and worms, soil moisture change law, the impact of fertilization level on characters of intercrops, economic benefit and so on. They are researched a little on part of soil conservation action, soil moisture, soil nutrient, and the underground portion of intercrop. Finally, the key technical issues for the intercropping on planting measures were emphasized. The date of seeding and transplanting time should be arranged reasonably, it is adopted that symbiotic system method of fertilizer application and rational planting denisity.
