How to do well the tending and Management of Taxus mairei Young Forest

Taxus is the most important anticancer plant at the present stage, which is planted in a large area. The method of tending its young forest is briefly introduced.

First, shading. Young trees of yew seedlings avoid strong light exposure, and shading must be the key after afforestation.

1. Mountain afforestation. In addition to afforestation under the canopy of sparse woodland, conventional afforestation in barren mountains or reforestation in cutting and burning sites should be planted with fast-growing shade trees in the first year or in the first year, and the interplanting method can be scattered planting, horizontal strip planting or inter-row planting. Tree species can choose fast-growing eucalyptus, Acacia, paulownia and so on.

two。 Grow on flat land. Refers to hilly wasteland, discarded remote dry soil or paddy field planting, these places have plenty of sunshine, long time, strong intensity, must be shaded.

Shading method:

① sets up shading net for shading: the height of the net should be above 3m. The net is a little higher, which is beneficial to ventilation, ventilation and shading. But the cost of this method is relatively high, generally speaking, the cost of one mu of woodland is about 900 yuan.

② plant shade trees: some fast-growing broad-leaved trees or fruit trees are planted in the middle of the yew woodland.

③ grows long-stalked crops for shade.

Second, discharging stains. Drainage is mainly aimed at the cultivation of abandoned remote paddy fields, because the paddy field is very flat, coupled with the barrier of the ridge, Rain Water is difficult to discharge, especially the deep mud field. There are a lot of Rain Water in spring and summer. The death of rotten roots of Taxus is often caused by long-term wetting. Method of discharging stains: 1. Change flat land planting to high ridge planting, monopolizing more than 20cm. two。 If the shading net is used to cover the shade, it is necessary to change a large area of the net into a small piece of shade, one or two boxes of one shading net per box. 3. Deepen and widen the footpath and surrounding drains, and open more drains. 4. If necessary, the field block system can be broken according to the terrain and cross the ridge from top to bottom. Straight open one to several larger gutters to facilitate Rain Water's catharsis.

Third, ploughing. The number of times of intertillage depends on the situation of the woodland, in principle, three times a month. The soil should be ploughed in time after rain, and the roots of the 1-2-year-old young forest should not be hurt or less damaged as far as possible. The root system of 1-2-year-old young forest is not very developed, and the middle tillage should not be too close to the root system, so as not to affect its growth. The mid-tillage depth is about 3-6cm. With the growth of Taxus mairei, the mid-tillage depth can be deepened year by year, and it can be reclaimed twice a year.

Fourth, weeding. Weeding can generally be combined with ploughing and carried out at the same time. According to the growth of weeds, 2mi 3 times a month (except in winter), to weed as soon as possible, early, small, except. Climbing and winding weeds must be removed so as not to entangle the young yew forest and affect its growth.

Fifth, irrigation. The number of irrigation depends on the weather and the water content of the woodland. In principle, irrigation is carried out as soon as the soil is dry. Keep the soil dry and wet.

6. Fertilizing. Fertilizer is mainly compound fertilizer, supplemented by urea, and can be combined with fully mature organic fertilizer, such as cake fertilizer, human feces and urine, poultry and livestock fertilizer and so on. Fertilization can be applied either by water or by dry application, but not too thick. Dry application can be combined with ploughing to bury fertilizer into woodland.

7. Disease and pest control. Taxus has not been found to have large-scale diseases and insect pests, but a small number of termites eat food, which can be controlled by termites, and the effect is good. The disease is mainly the root rot of 1-3 years young forest, which occurs mostly in spring and summer when Rain Water is more. In addition to planting in high ridges and opening good drains, carbendazim and Jinggangmycin can be used for drug control, and the effect of application is also very good.
