Problems solved by technology

This method solves the problem of low yield and poor growth of yew, but the fertilizer is directly covered with fertilizer on the soil, and the weeds with broken roots are added to cover the fertilizer, and the utilization rate of the fertilizer is low.
[0004] Topdressing after yew afforestation is generally done by spreading or furrowing, the former has low fertilizer utilization efficiency, and the latter has low fertilization efficiency

Embodiment 1

[0028] Fertilization method: 1. When afforestation, the size of the hole is 50*50*40, and 2.5kg / plant of organic fertilizer is applied to the bottom. After applying, backfill 1 / 3 of the soil, and then plant the container seedlings to ensure that the root system of the container seedlings is isolated from the fertilizer; Organic matter content ≥ 50%, N+ PO 2 +K content ≥ 6%, water content ≤ 15%, raw materials: fermented human and animal manure, rapeseed cake.

[0029] Topdressing: In a relatively flat terrain, use the fertilization tool involved in this technology to equidistant 8 points around the crown of the tree, and apply special compound fertilizer (N: PO 2 : K ratio is 16:7:16) 60 g; in mountainous areas with a slope greater than 30°, use the fertilization tools involved in this technology to equidistant 4 points on the straight line parallel to the canopy drip line (uphill) and the contour line. Fertilize 120g at a point, and in the next year, 4 points are equidistant ...

Embodiment 2

[0034] Fertilization method: 1. When afforestation, the size of the hole is 50*50*40, and 2.5kg / plant of organic fertilizer is applied to the bottom. After applying, backfill 1 / 3 of the soil, and then plant the container seedlings to ensure that the root system of the container seedlings is isolated from the fertilizer; Organic matter content ≥ 50%, N+ PO 2 +K content ≥ 6%, water content ≤ 15%, raw materials: fermented human and animal manure, rapeseed cake.

[0035] Topdressing: In a relatively flat terrain, use the fertilization tool involved in this technology to equidistant 8 points around the crown of the tree, and apply special compound fertilizer (N: PO 2 : K ratio is 17:9:13) 60 g; in steep terrain, use the fertilization tool involved in this technology to equidistant 4 points on the straight line parallel to the canopy drip line (uphill) and the contour line, and fertilize 120g at each point In the following year, 4 points are equally spaced on a straight line parall...

Abstract

The invention discloses a fertilizing method suitable for growth of young Taxus wallichiana forest. A special base fertilizer used in the method takes human and animal excreta and cake-shaped rape seed dregs as raw materials, wherein the content of organic matters is more than or equal to 50%, the content of N + PO2 + K is more than or equal to 6%, the water content is less than or equal to 15%, and other toxic and harmful substances are not contained; a special compound fertilizer comprises N, PO2 and K, wherein the ratio of N to PO2 to K is 16: 7: 16 or 17: 9: 13, and the nutrient content is more than or equal to 39%. The fertilizing method comprises the following steps of applying 2.5 kg of special base fertilizer to each plant before afforestation, and topdressing 480g of special compound fertilizer to each plant every year after afforestation; By adopting a simple fertilizing tool related to the method, the fertilizing efficiency is improved by at least 100%. According to the fertilizing method, the fertilizer is uniformly distributed around the tree, and the depth reaches 30cm, so that the effectiveness of the fertilizer is ensured, and the stress resistance of the tree is also improved.

Description

technical field [0001] The invention belongs to the technical field of yew young forest cultivation, and in particular relates to a fertilization method suitable for the growth of southern yew young forests. Background technique [0002] Southern yew ( Taxus wallichiana var. mirei (Lemée H. Léveillé.) L. K. Fuet Nan Li) is Taxaceae (Taxaceae) Taxus genus ( Taxus L.) A variant of Taxus Himalayan, which is a multifunctional tree species that integrates medicinal, timber and ornamental uses. It is also a rare and endangered plant. It is isolated from its bark and branches and leaves and has a significant anticancer active ingredient - paclitaxel. It is an internationally recognized anticancer drug for the treatment of breast cancer, ovarian cancer, non-small cell lung cancer, colon cancer and other cancers, with definite curative effect and small side effects. At present, the wild resources of Taxus chinensis in the south are scarce, and for the huge market demand, it i...
