我县黄庄地区近3年播种紫花苜蓿7000亩,由于采取了一系列科学治理杂草的方法,使苜蓿地杂草明显减少,苜蓿生长旺盛,现将具体方法介绍如下: 一、苜蓿与草木犀混播 由于草木犀适应性很强,生长繁茂,可以利用本身庞大的枝体结构来控制杂草的生长。草木犀虽比苜蓿生长旺盛,但其生命力仅两年,结籽后自行消亡,根基腐烂后如同一个小粪坑,为苜蓿后期生长准备好了肥源。根据草木犀这些特点,我们在播种时,采取了苜蓿与草木犀混播的方法,即每50公斤苜蓿种籽加0.5公斤草木犀种籽。不应过多,因草木犀种籽成熟
Huangzhuang County in the past three years planted alfalfa 7000 acres, due to take a series of scientific methods of weed control, alfalfa weeds significantly reduced, alfalfa vigorous growth, the specific methods are described below: First, alfalfa and grass Osmanthus mixed sowing due to strong adaptability of rhododendron, growing lush, you can use its own huge branch structure to control the growth of weeds. Although the herbaceous rhinoceros grows stronger than alfalfa, its vitality is only two years. After the seed has died, it disappears on its own. After the basic decay, it resembles a small pit and provides a fertilizer source for the later growth of alfalfa. According to the herbaceous rhinoceros these characteristics, we planted at the time, alfalfa and grass rhizome mixed broadcast method, that is, every 50 kg of alfalfa seeds plus 0.5 kg of grass rhinoceros. Should not be too much, because the grass rhinoceros seeds mature
