I. About green manure

Taiwan is located in the subtropical zone, the climate is high temperature and humid, the organic matter in the soil decomposes rapidly, the soil nutrients are easy to be lost due to intense leaching, and the soil fertility is poor. Early farmers planted green manure crops or self-made compost to improve the local, to maintain agricultural production, to the sixties chemical fertilizer is widely used, because of its quick efficiency of tools, in order to improve agricultural productivity, chemical fertilizer is used in large quantities, over time, often cause soil acidification, and leave too much nitrate pollution soil and groundwater, so that soil fertility decline and ecological environment deterioration adverse effects. Therefore, Taiwan urgently needs to establish an agricultural production system that reduces the use of chemical fertilizers, pesticides and energy to prevent the deterioration of the ecological environment.

Green manure is a crop whose fresh plants are ploughed into the soil as fertilizer or used to improve soil physical and chemical properties. Therefore, planting green manure crops can increase the organic matter content in the soil, improve soil physical, chemical and biological properties, especially leguminous green manure crops. Its symbiotic rhizobia can fix nitrogen in the air, increase the source of nitrogen in the soil, prevent weeds from growing, and have the function of soil and water conservation. Green manures such as rape also have multiple functions such as abundant winter nectar and relieving the pressure of winter vegetable overproduction. In recent years, the living standard of Chinese people has greatly improved, and more and more attention has been paid to the quality of agricultural products. Cultivation of green manures not only protects farmland for sustainable production, but also improves crop yield and produces healthy foods. It is really worth popularizing.

II. Applicable green manure crops

The importance of green manure crops suitable for cultivation in Taiwan can be summarized as follows:

(i) Increase soil nutrients and promote their solubility.

(2) Increase the organic matter content in the soil.

(3) It has the function of covering soil and soil conservation on hillside land.

(4) to prevent weeds from growing on fallow or fallow farmland and it is difficult to recultivate.

(5) it can be used as livestock feed and human vegetable food.
