本研究旨在证明刈割次数对高冰草的作用。为获得最高产量,对试验地按需要从2月到生长季结束实施灌溉,并间隔2个月每公顷施氮肥112公斤,刈割每一周、二周、四周进行一次。结果表明,从春天起收割产草量较高,夏季以后下降,试验地每四周刈割一次产草量比每一或二周的高。可以这样认为。轮牧可以提高生产率。在夏季营养含量最高。刈割次数少,磷、钾含量高,但钙镁含量低。这在给放牧牛补充矿物质上,显得非常重要。 The purpose of this study is to demonstrate the effect of mowing times on Agropyron. In order to obtain the highest yields, irrigation was conducted experimentally from the end of February until the end of the growing season on an as-needed basis with 112 kg of nitrogen fertilizer applied per hectare for 2 months. Mowing was carried out every week, two weeks and four weeks. The results showed that harvesting started from spring with a high yield and decreased after summer. The grass yield was mowed every four weeks longer than every one or two weeks. Can think so. Rotation can improve productivity. The highest nutritional content in summer. Mowing less, phosphorus, potassium content is high, but low calcium and magnesium content. This is very important for the grazing of cattle to add minerals.
