Abstract
Testing methods for rapeseed quality are introduced in this paper. Meanwhile, based on the current status of rapeseed cultivation in Wangjiang County of Anhui Province, high yield cultivation techniques for rapeseed are analyzed and summarized from the aspects of variety selection, seed treatment, field fertilizer and water management, and disease and pest control. The core indicators of testing of rapeseed seed quality, include moisture determination (low-constant temperature drying method, requiring a moisture content ≤9.0%), cleanliness analysis (cleanliness≥98.0%), and germination test (calculating germination rate after 7 days of cultivation at 20 °C), and varietal purity identification (varietal purity ≥ 86%), which provide technical support for seed quality safety. High yield cultivation techniques include choosing high-resistance varieties with moderate growth periods and suitable for mechanical harvesting; preparing the field before sowing and preventing seeds from carrying pests and diseases through sun-drying and chemical seed dressing; implementing intertillage and weeding after seedling establishment and before canopy closure, applying fertilizers scientifically with particular attention to sulfur fertilizer application in the soil, and cleaning the furrows between plots, furrows across plots, and surrounding furrows of rapeseed fields in a timely manner to achieve “irrigation in drought and drainage in waterlogging”; focusing on preventing sclerotinia stem rot, aphids, and cabbage worms by comprehensively using agricultural, physical, biological, and chemical control methods; and harvesting in a timely manner according to weather conditions and rapeseed maturity. This paper provides a reference for high yield rapeseed cultivation and seed quality control in similar regions.关键词
