一、试验目的随着棉花生产快速向精准农业发展的同时,种子包衣技术也在不断完善,这对棉花生产的作用尤为重要。2004年在48团运用 KZ-1号新型种衣剂,观测在整个棉花生育期的抗虫、抗病性,以确定适合我区病虫害综合防治的种衣剂。二、试验单位及条田选择1.试验单位:4连。2.试验条田:四斗2号、三斗1号条田。3.土质情况:粘土。4.试验面积:8公顷。5.前茬:棉花连作9年、12年。三、试验材料及设计
First, the purpose of the experiment With the rapid development of cotton to precision agriculture, seed coating technology is also constantly improving, which is particularly important for the role of cotton production. In 2004, 48 groups of KZ-1 new seed coating agents were used to observe the insect resistance and disease resistance throughout the growing period of cotton so as to determine the seed coating agent suitable for comprehensive pest control in our region. Second, test units and field selection 1. Test unit: 4 even. 2. Experimental field: four bucket 2, three bucket 1 field. 3. Soil conditions: clay. 4. Test area: 8 hectares. 5. The former crop: cotton even for 9 years, 12 years. Third, the test materials and design
