基本解释

This study opens up a new area for mulching materials for dry land wheat.
該項研究爲旱地小麥覆蓋材料開辟了新的領域。
The effects of different mulching materials on crop yields were mainly due to their effects on soil environments and then the improvement on the growth and development of crops.
不同覆蓋物的增産機理主要是由於它們在不同程度上改善了作物生長的土壤環境條件，從而不同程度地促進了作物的生長發育。
Newly developed genseng-mulching materials promoted genseng growing as a result of the red and blue long waves that the sun gave off through them, and possessed due transmissivities.
新型人蓡棚覆蓋材料，在陽光下具有紅、蘭長波光澤而促進人蓡生長，透光率適儅，可少用或不用草簾，不僅省工省時還能降低覆蓋成本21．5％。
