Water and fertilizer integrated special fertilizer for young catalpa bungei forest and fertilizing method

Abstract

The invention relates to a water and fertilizer integrated special fertilizer for young catalpa bungei forests and a fertilization method. The water and fertilizer integrated special fertilizer comprises a first-year special fertilizer and a second-year special fertilizer, the first- year special fertilizer is prepared from the following components in parts by weight: 22 to 26 parts of N, 7 to 9 parts of P2O5 and 15 to 18 parts of K2O; and the second -year special fertilizer is prepared from the following components in parts by weight: 27 to 31 parts of N, 8 to 12 parts of P2O5 and 18.5 to 21 parts of K2O. By means of the method, the yield and quality of the catalpa bungei young forest can be effectively improved.

Description

technical field [0001] The invention relates to the field of agriculture, in particular to a special fertilizer for the integration of water and fertilizer for young catalpa forests and a fertilization method. Background technique [0002] Catalpa bungei is a precious and high-quality timber tree species traditionally cultivated in warm temperate and subtropical regions in my country and a famous ornamental tree species in gardens. For a long time, the country and the government have attached great importance to the promotion and development of catalpa. At present, the supporting cultivation techniques such as irrigation and fertilization are relatively lacking, and, as a precious fast-growing tree species, when it is planted in a large area (especially in arid areas), its consumption of water and fertilizer resources is easily affected by society. of general concern. At present, the traditional management method leads to a serious waste of fertilizer and water resources i...

Problems solved by technology

[0004] In previous studies, domestic experts and scholars have carried out a lot of research work on the research and development of catalpa fertilization technology, but mainly focused on the morphology and physiological response of catalpa seedlings, and few research reports on fertilization of catalpa plantation. The research on tree water and fertilizer integration is still blank
