黑龙江籽用工业大麻—紫苏轮作栽培技术要点
Key technical points of grain industrial hemp-perilla rotation cultivation in Heilongjiang Province
摘要
Abstract
The tetrahydrocannabinol(THC)content of grain industrial hemp is less than 0.3%,the crude protein content is over 25%,and the oil content of the seeds is high.It has high application value in the food and chemical fields.The key technical points of the grain industrial hemp-perilla rotation cultivation model in Heilongjiang Province were summarized.In terms of land selection and preparation,grain industrial hemp requires deep and loose loam soil layers;perilla is suitable for planting on meadow soil.In terms of variety selection,grain industrial hemp uses varieties with THC content below 0.3%(such as Longdama No.6,Longdama No.12)from early April to mid May;perilla frutescens is selected for its suitable growth period based on accumulated temperature and sown in early to mid May.In terms of field management,grain industrial hemp is subjected to pre seedling closed weeding and post seedling manual weeding.When the seedling height is 40 cm,the ridge is closed,and scientific irrigation is carried out according to water demand during the growth period;perilla frutescens requires closed weeding,intercropping,three rounds of tillage weeding,and water and fertilizer management.The prevention and control of pests and diseases follow the principle of prevention first and comprehensive control.Industrial hemp focuses on the prevention and control of brown spot disease,rot disease,corn borer,etc.,while perilla focuses on the prevention and control of spot blight disease,rust disease,and spider mites.In terms of harvesting and processing,grain industrial hemp is harvested,sun dried,and threshed when the seeds are 90%mature;oil perilla is harvested from late September to mid October,while leaf perilla is harvested when the plant height exceeds 50 cm.This crop rotation model can enhance farmland productivity and achieve increased yield and efficiency.This article provides a reference for improving the planting environment of crops,and solving problems such as continuous cropping obstacles in farmland.关键词
