我县天然分布的沙棘林,大多生长在沟坡和田埂上,由于交通不便,人们很少对其进行经营管理。加之天然沙赫林中雄株过多,因而沙棘果产量较低,一般亩产25～55公斤,仅为人工林产量的30％左右。改造这些沙棘林应从以下诸方面着手。 1、调节密度,增加光照。天然沙棘林生长的非常稠密,不能接受充足的光照,因而长势弱,结果量少,而且果实小。今后应按照不同的经营目的,调节其密度。如以采果为目的林分则密度不宜大,一般以每亩200丛,每丛枝条不多于20株为宜。
Natural distribution of seabuckthorn forest in our county, most of them grow in the ditch slope and field ridge, due to traffic inconvenience, people rarely carry out their management. In addition, there are too many male plants in natural Shahelin. Therefore, the yield of seabuckthorn fruits is relatively low, generally 25 to 55 kg per mu, only about 30% of the total yield of plantations. The transformation of these seabuckthorn should proceed from the following aspects. 1, adjust the density, increase the light. Natural Hippophae rhamnoides grows very densely and can not receive sufficient light, so it grows weakly, the result is small, and the fruit is small. In the future should be in accordance with the different business purposes, adjust its density. As for the purpose of picking fruit for the forest density is not suitable for large, generally 200 plexus per mu, no more than 20 per bundle of branches is appropriate.
