Special compound fertilizer for raising seedlings of CephalotaxusfortuneiHook.f outdoors and application method thereof

Abstract

The invention relates to the seedling raising technology in agriculture and forestry and in particular relates to a special compound fertilizer for raising seedlings of CephalotaxusfortuneiHook.f outdoors and an application method thereof. The special compound fertilizer comprises a water retaining and growth promoting rooting agent for transplanting and a special fertilizer for leaf surfaces, wherein the water retaining and growth promoting rooting agent for transplanting is prepared by mixing indolebutyric acid, 2,4-dichlorphenoxyacetic acid, humic acid, potassium nitrate, magnesium sulfate, calcium chloride, 6-BA, sodium polyacrylate and carbendazim; the special fertilizer for leaf surfaces is prepared by mixing compound amino acid, urea, monopotassium phosphate, zinc sulfate, compound sodium nitrophenolate, DA-6 and Tween. The water retaining and growth promoting rooting agent for transplanting and the special fertilizer for leaf surfaces are fully and effectively compounded according to the requirements of CephalotaxusfortuneiHook.f woods for nutrient elements, and then the requirements in the process of transplanting CephalotaxusfortuneiHook.f from greenhouses to outdoor seedling nurseries are met and nutrients are quickly provided for CephalotaxusfortuneiHook.f seedlings to enhance the adaptive capacity of CephalotaxusfortuneiHook.f, thus shortening the rejuvenation period and the nursery coming-out time, increasing the survival rates of the CephalotaxusfortuneiHook.f seedlings and reducing the cost of industrialized production.

Description

technical field [0001] The invention relates to agriculture and forestry seedling raising technology, in particular to a composite fertilizer specially used for open-air seedling raising of clover cedar and its application method. Background technique [0002] Cephalotaxus fortunei Hook·f belongs to Cephalotaxus fortunei Hook·f, which belongs to Cephalotaxus fortunei Hook·f, and is a unique species in my country; Daozhen Autonomous County, Guizhou Province is the original place of my country Cephalotaxus fortunei Hook·f, and it is also the center distribution place of Cephalotaxus fortunei Hook in the world. The ester alkaloids contained in the harringtonine plants have anti-cancer activity, especially harringtonine and homoharringtonine have significant curative effects on leukemia, melanoma, lung cancer, breast cancer, and brain tumors. Cedarwood is dioecious, with less fruit, slow seed propagation, and difficult natural regeneration and sowing seedlings. It cannot meet th...

AI Technical Summary

Problems solved by technology

Cedarwood is dioecious, less fruit, slow seed reproduction, natural regeneration and sowing seedlings are more difficult, can not meet the large demand for industrial raw materials of Cedarwood, and is not conducive to the protection of Cedarwood natural resources

[0003] In the prior art, in order to meet the demand of the market for the three-pointed fir plants, many attempts have been made on the industrial production of the three-pointed fir. Full-illumination automatic intermittent spraying cutting system. After 6 months of cultivation in the intelligent greenhouse, the cuttings of the three-pointed fir have healed and rooted and survived. , the plants have weak adaptability, which will lead to the death of transplanted seedlings, prolong the slow seedling period, affect the time of nursery emergence, increase the cost of factory production, and affect economic benefits
