Embodiment Construction

[0026] A technique for increasing the number of Qinghai spruce cones and preserving flowers, comprising the following steps:

[0027] (1) Fertilization to promote flowering: From March to April, as the temperature increases, the sap of Qinghai spruce begins to move, and the plants with no flowers and few flowers are applied with 12-24-12 type nitrogen, phosphorus and potassium ternary compound fertilizer ( Produced by European groups such as BASF, 12-24-12 type nitrogen, phosphorus and potassium ternary compound fertilizer, namely N-P 2 o 5 -K 2 O, which means that the corresponding percentage content is 12% nitrogen, 24% phosphorus, and 12% potassium, ensuring that the content of the three elements of NPK is 1:2:1) and biological diamine (Hebei New Century Zhoutian Bio Biological diamine produced by Science and Technology Co., Ltd.), 12-24-12 type NPK ternary compound fertilizer and biological diamine are mixed according to the volume of 2:1, and transported to Qinghai spru...

Abstract

The invention relates to a quantity-increasing and protecting method of spruce cones in Qinghai. The quantity-increasing and protecting method of the spruce cones in Qinghai comprises (1) fertilizing to promote the spruce cones; (2) spraying a flower-promoting agent; (3) performing root-pruning to promote the spruce cones and (4) protecting the spruce cones and preventing pests. The quantity-increasing and protecting method of the spruce cones in Qinghai has the advantages of being simple and easy to operate; effectively increasing cone quantities of spruces in Qinghai; establishing a good precondition for the sexual reproduction of the spruces in Qinghai, playing an important role in increasing the seed yield and improving the seed quality of the spruces in Qinghai and then being capable of effectively restoring the ecological environment of local spruce forests in Qinghai due to the fact that the current situations that the quantity of the spruce cones in Qinghai is small, the distribution of male cones and female cones is not easy to pollinate, the spruce cones are susceptible to plant diseases and insect pests and the like are improved and providing a good popularization value.

Description

technical field [0001] The invention relates to the propagation technology of Qinghai spruce, in particular to a technology for increasing the number of flower cones and preserving flowers of Qinghai spruce. [0002] Background technique [0003] Qinghai spruce (Picea crassifolia Kom.), a plant belonging to the genus Picea Dietr. of the family Pinaceae, is a unique tree species on the northeast edge of the Qinghai-Tibet Plateau in China. It is distributed in Gansu, Qinghai, Ningxia, Inner Mongolia and other provinces in Northwest China Qu (Ding Guomin, et al. A preliminary study on the population dynamics of Picea spruce in Qilian Mountains, Gansu [J], Journal of Plant Resources and Environment, 2005,14(4):36-41.). Qinghai spruce has the advantages of excellent material, tall and straight trunk, cold resistance, drought resistance, and long life. It is an ideal tree species for landscaping and water and soil conservation. At the same time, it has the functions of sequester...
