辽西地区十年九春旱,对春季造林苗木的成活很不利,积极采取防旱、抗旱措施,对提高造林成活率十分必要。1.选用水分条件较好的宜林地。土壤水分平地好于山地,山地的阴坡好于阳坡,山下部好于山上部,植被条件好的地块好于植被条件差的地块,要按着适地适树的原则,造林地点尽量选在水分条件较好的沿河平地和植被条件较好的山地中下腹,以及上年雨季前整地的地块上。这样可以充分利用土壤墒情,减少抗旱灌水的工作量。
In the western Liaoning Province, the ten-year spring drought of nine years is very unfavorable to the survival of the afforestation seedlings in spring, and actively adopts the measures of drought prevention and drought relief, which are necessary to improve the survival rate of afforestation. 1. Choose the better water conditions should be woodland. The soil moisture level is better than the mountainous area. The shady slope in the mountain area is better than the sunny slope. The mountainous area is better than the mountainous area. The land with good vegetation condition is better than the land with poor vegetation condition. According to the principle of suitable tree planting, Try to choose the better water conditions along the river plains and vegetation better conditions in the lower abdomen in the mountains, as well as land preparation before the rainy season last year plots. This can make full use of soil moisture, reduce the workload of drought irrigation.
