Special Fertilizer for Improving Seed Yield of Pine Masson and Fertilization Method

Abstract

The invention discloses a special fertilizer for increasing yield of seeds of masson pine. The special fertilizer comprises a cone expanding fertilizer and a blossom-promoting and fruit-protecting fertilizer. The cone expanding fertilizer is mainly composed of an organic fertilizer, macro-elements, microelements, a bio-bacterial preparation and talcum powder, and the blossom-promoting and fruit-protecting fertilizer is mainly composed of an organic fertilizer, macro-elements, microelements, a bio-bacterial preparation, talcum powder and chlormequat chloride. The invention also provides a corresponding fertilizing method, wherein the cone expanding fertilizer is applied in March every year in a manner of furrow fertilization, and the blossom-promoting and fruit-protecting fertilizer is applied in August in a manner of furrow fertilization. The special fertilizer is suitable for seed trees of masson pine in fruiting period. By applying the special fertilizer in different formulas, demand on nutrients during a growth period of the cones of the masson pine is satisfied well. The special fertilizer increases fruit setting rate, promotes differentiation of female and male flowers, increases the content of organic substances in soil and improves soil environment, and achieves high and stable production in a seed orchard.

Description

technical field [0001] The invention belongs to the technical field of plant fertilization, and in particular relates to a special fertilizer for improving the seed yield of Pinus massoniana and a fertilization method. Background technique [0002] Masson pine is the most important fast-growing and high-yielding timber forest species in southern my country. It has made a major contribution to the realization of the "double increase" goal of my country's forestry and occupies an important position in the national economy. According to statistics, 16.9% of the forest stock in southern my country comes from Pinus massoniana. In addition, the whole body of masson pine is full of treasures, which has extremely high comprehensive utilization value. In addition to wood, there are also various products such as turpentine and pine pollen. Enhancing the management of fast-growing, high-yielding and high-yielding resin plantations of Pinus massoniana is of great significance for incre...

AI Technical Summary

Problems solved by technology

Although there are also studies on fertilization with soil testing formula, they only simply measure a large number of elements in the soil, and do not combine the development characteristics of Pinus massoniana and the nutrients required for different stages of cone development to fertilize, and the fertilization time is also related to the fast-growing and high-yielding forest. Consistent, without considering the characteristics of cone development and the development of male and female flowers

In addition, previous studies did not consider that it takes nearly 2 years for the development of cones of Pinus massoniana. It is necessary to promote the development of cones in the first year and to control vegetative growth to ensure the development of male and female flowers in the second year.
