Abstract

The invention discloses a pinus massoniana L. middle age forest specially used fertilizer. The pinus massoniana L. middle age forest specially used fertilizer is mainly composed of, by weight, 17 to 25% of an organic fertilizer, 65 to 75% of major elements, 1.5 to 3.5% of trace elements, 3 to 5% of talcum powder, and 6 to 9% of plant ash, wherein in the major elements, nitrogen, phosphorus, and potassium effective components account for 20 to 25%, and in the trace elements, effective components account for 1.5 to 3.5%. The invention also discloses a corresponding fertilization method, and reasonable fertilization time and fertilizing amount. The pinus massoniana L. middle age forest specially used fertilizer is suitable for plants in pinus massoniana L. middle age forest and mature forest, is capable of completely satisfying requirements of plants in pinus massoniana L. middle age forest on nutrients, modifying soil, increasing resistance, improving photosynthesis conditions, increasing pine gum yield, accelerating growth of forest, and providing support for realization of rapid growth and high yield of pinus massoniana L. middle age forest.

Description

technical field [0001] The invention belongs to the technical field of plant fertilizers and fertilization, and in particular relates to a special fertilizer for masson pine middle-aged forests and an application method. Background technique [0002] Masson pine (Pinus massoniana L.) is one of the important native tree species in subtropical regions of my country, distributed in 17 provinces and cities. Masson pine is an important source of raw materials for my country's papermaking, wood processing, forestry chemical industry and other industries. Every year, my country produces 15 million m of masson pine wood 3 , The output of rosin is 600,000-800,000 tons. There are more than 14 million hectares of masson pine forests in my country. With the continuous destruction of natural forests, the proportion of artificial forests is increasing, and the annual afforestation area reaches tens of thousands to one hundred thousand hectares. Similar to the overall situation of my cou...
