沿海农区麦田杂草防除技术研究

根据沿海农区麦田杂草发生危害现状 ,麦田杂草可分为禾本科和阔叶类 2大类 ,进行了硬草 (禾本科恶性杂草之一 )、泽漆 (新上升难治阔叶类杂草 )的发生危害规律和有关生物学特性的基础研究 ,重点研究了控制麦田硬草、泽漆的关键措施 ,明确了应用化学除草剂 (骠马、乙草胺、异丙隆、使它隆、苯磺隆及其复配剂 )的核心所在 ,结合其它有关专题研究结果 ,在先进的原则策略指导下 ,组装了沿海农区麦田杂草长效治理技术措施。

Studies on the Control Techniques of Weed in Wheat Fields in Coastal Area

According to the present condition of weeds in wheat field of agricultural district in coastal area, weeds in wheat field can be divided into two types: Gramineae and broadleaf-weed. We studied on the occurrence regulation and the relevant biology characteristic of Sclerochloa kengiana (one of the malignant weeds of Gramineae) and Euphorbia helioscopia (one of the new rising broadleaf-weeds). We put stress on studying the key measure of Sclerochloa kengiana and Euphorbia helioscopia in wheat field , pointed out the key of applying chemistry herbicide (diclofop-methyl, acetochlor, isoproturon, fluroxypyr, express and admixture of them). Uniting results of other special subject researching and excellent principles , we established the measures of the control techniques of weed in wheat fields in coastal area forever.
