Cultivating method of walnut fruit-timber forest

Abstract

The invention relates to a cultivating method of a walnut fruit-timber forest. The method includes the following steps of firstly, selecting black walnut seedling nursery stock which is 1-2 years old; secondly, preparing a land and building a black walnut timber forest; thirdly, immediately conducting irrigation after building the forest, conducting irrigation for the second time one week later, and conducting management through a black walnut forest management method; fourthly, stumping all alive trees after the black walnut nursery stock survives and grows for one year and before the spring germination in the second year, wherein the stumping height is 5 cm above the earth surface of the trees; fifthly, enhancing the water and fertilizer management after stumping, conducting bud fixing when coppice shoots grow to be 20-30 cm long, selecting the most robust straight coppice shoot as the kept cultivating shoot, and shearing off or wiping away all other coppice shoots; sixthly, conducting grafting, wherein grafted parts are 2.2-2.4 m higher than the cultivated black walnut tree trunk earth; seventhly, conducting grafting management; eighthly, conducting renewing and harvesting. According to the life cycles of walnut and black walnut, harvesting and renewing generally need to be conducted every 50-70 years according to the management strength of the fruit-timber forest.

Description

technical field [0001] The invention relates to a method for cultivating a walnut fruit material dual-purpose forest. Background technique [0002] It is the country's development strategy to fully implement the forestry development strategy focusing on ecological construction and to better play the five functions of forestry ecology, economy, society, carbon sinks and culture. In the near future, my country will complete 6 million hectares of new forests every year. Afforestation implements five major strategies, including the national land ecological security barrier strategy, the national timber and grain and oil safety strategy, the carbon sequestration and emission reduction strategy, the greening strategy to benefit the people, and the prosperity ecological and cultural strategy. [0003] Walnut is the most important nut tree and woody oil tree species in the world, ranking first among the four major nuts in the world. my country is one of the origins and distribution c...

Problems solved by technology

Conventional walnut economic forests, black walnut timber forests, and fruit forests are cultivated in different ways—walnut economic forests aim at high-quality, high-yielding walnuts, and cannot produce high-quality timber; black walnut timber forests aim at high-quality, high-yielding wood, while There is basically no high use value, and there are few nuts, which are basically unusable; neither of them can achieve the effect of harvesting both fruits and materials, especially for excellent land and areas with a high degree of intensive management in agricultural areas, making land, space and Water use efficiency is suboptimal
