1.修筑水土保持工程。在干旱和水土流失严重的地方,于山杏林地修筑水土保持工程,是一项有效的增产措施。水平沟、鱼鳞坑等水土保持工程能起到拦水、蓄水、保土作用,可改善土壤水分、养分条件,促进林木生长,可有效地提高结实率和单位面积产量。实践证明,在山杏林地修筑水土保持工程,比未修工程的单位面积产量提高60％左右。
1. To build soil and water conservation projects. In the areas where drought and soil erosion are serious, construction of soil and water conservation projects in the mountain forest land is an effective stimulation measure. Water and soil conservation projects such as horizontal ditch and fish-scale pit can play a role of blocking water, storing water and preserving soil, improving soil moisture and nutrient conditions, promoting forest growth, effectively improving the seed setting rate and yield per unit area. Practice has proved that the construction of soil and water conservation projects in the mountain apricot forest, unpaved construction unit area yield increased by 60%.
