马兰为我市桑园多年生恶性阔叶杂草,发生较普遍,危害较重,人工难以清除。本试验研究了草甘膦不同剂型、不同施药期的除草效果以及可溶性粉剂加硫酸铵的增效作用。试验在海宁县盐官蚕种场中杆桑园进行,株行距0.65×2米,小区面积:春施6.67米~2,夏施和深秋施均为66.7米~2,重复三次。药剂对水30升/亩,每升药液加洗衣粉2克,用工农16型背包喷雾器钢玉喷片喷孔1毫米喷雾。药前每小区定二点,考查药前药后马兰活草株数,计算存活率。对不同施药期药后
Malan for our city mulberry perennial malignant broadleaf weeds, more common, more harmful, difficult to remove by hand. This experiment studied the different dosage forms of glyphosate, herbicidal effect in different application periods and the synergistic effect of soluble powder and ammonium sulfate. The experiment was carried out in the pole mulberry field of Yanbian silkworm farm in Haining County. The row spacing was 0.65 × 2m. The plot area was 6.67m ~ 2 for spring and 66.7m ~ 2 for summer and autumn, repeated three times. Pharmacy on the water 30 liters / acre, plus 2 grams of liquid detergent per liter, workers and peasants 16-type backpack sprayer spray jade jade spray 1 mm hole. Pre-drug each district set two points to test the drug Malan live grass after the number of plants, calculate the survival rate. Different doses of medicine after
