多变小冠花是多年生草本豆科植物。用于防止水土流失,培肥土壤、饲养牲畜、美化环境等方面,取得了良好的效果,引起了各方面广泛的重视。近年来,正在我国迅速推广应用。本文就多变小冠花对改土培肥的作用及有效利用方式进行论述。通过在多变小冠花地里种植玉米、矮生苹果及梨树的试验;定点测定不同牧草、绿肥种植条件下土壤水分的变化规律,看出: 1.多变小冠花有较强的蓄水保墒能力。 2.种植多变小冠花有利于土壤有机质的积累和氮素供应,有利于疏松土壤、抑制杂草、提高土壤肥力。 3.在多变小冠花复盖下,种植的玉米穗粒多,千粒重高,根系发达,光合面积大,产量显著增加。 4.在矮生果园种植多变小冠花能促进果树早萌发,早开花结果,提高座果率。因此发展多变小冠花是保持水土,培肥土壤的一项有效措施。
Changeable small crown is a perennial herb legumes. It is used for preventing soil and water loss, fertilizing the soil, raising livestock, beautifying the environment, and has achieved good results. It has drawn wide attention from all sides. In recent years, it is being popularized and applied rapidly in our country. In this paper, the change of small crown of Cunninghamia to improve the role of soil and fertilizers and effective use of the method are discussed. Through the experiment of planting corn, dwarf apple and pear in a variety of small crown flowers, the change rule of soil moisture under different forage and green manure planting was determined by spot-by-point method. The results showed that: Water storage capacity. 2. Variety of small crown planting conducive to the accumulation of soil organic matter and nitrogen supply, is conducive to loose soil, inhibit weeds, improve soil fertility. Under the changeable crown of small flowers, the ear of corn is planted more, the grain weight is higher, the root system is developed, the photosynthetic area is bigger, and the yield is increased obviously. 4. In the dwarf orchard planting changeable small crown of flowers can promote early germination of fruit trees, early flowering results, improve fruit rate. Therefore, the development of changing small crown is to maintain soil and water, soil fertility is an effective measure.
