Method for building early high-yield cutting orchard by macadamia nut grafted seedlings

Abstract

The invention discloses a method for building an early high-yield cutting orchard by macadamia nut grafted seedlings, and belongs to the technical field of reproduction of improved varieties of foresttrees. The method includes the steps of cutting orchard building and management, and cutting tree management and regulation. Particularly, a yellow loam flat land or hilly sloppy land facilitating drainage and irrigation is selected to build the orchard, the mean annual temperature of the land is 19-23 DEG C, the extreme low temperature of the land is higher than or equal to 1.5 DEG C, the annualrainfall of the land is larger than 1100mm, the altitude of the land is smaller than 800m, and the soil layer of the land is larger than 50cm. Grafted seedlings (with the height larger than or equalto 130cm, the sprouting thickness larger than or equal to 1cm, the sprouting length larger than or equal to 70cm and the branching number larger than or equal to 6) of 3-5 local mainly-planted macadamia nut fine varieties are planted, soil, water and fertilizer management and pest control are performed, cutting can be performed in autumn and winter of the year of planting, and management is enhanced to improve production and quality of cuttings after cutting. The macadamia nut cutting orchard is built by the method, and production is early as cutting can be performed in autumn and winter of the year of planting. The cuttings reaching design capacity are improved by 3 times or more as compared with conventional cuttings, and yield is high. The thickness of most cuttings is 0.5-1.0cm, internodes are uniform in density, and the cuttings are high in degree of lignification and excellent in quality.

Description

technical field [0001] The invention relates to the technical field of forest tree breeding, in particular to a method for constructing an early-abundance and high-quality ear-picking nursery by grafting macadamia nuts with large seedlings, and belongs to the technical field of forest tree breeding. Background technique [0002] Macadamia( Macadamia spp.), also known as macadamia nut, is native to Australia and belongs to the genus Macadamia (Proteaceae). Macadamia F. Mull), is an emerging perennial woody oil tree species and high-grade nut crops in the tropics. Among the many dried fruits in the world, the macadamia nut has the highest economic value and has always been known as the "King of Nuts". [0003] Macadamia nuts were introduced into my country around 1910, but commercial planting did not begin until around 1980. In recent years, my country's macadamia nut industry has developed rapidly. According to statistics, in 2015, the planting area of ​​macadamia nuts ...

Problems solved by technology

[0004] At present, the supply of macadamia nut spikes mainly comes from traditional production orchards. After a large number of spikes are harvested in the production orchard, it will not only have a great impact on the yield of the current year and the next year, but also affect the quality of the spikes, and it is inevitable that there will be mixed fruit or low-quality branches in the spikes. , resulting in low quality of grafted seedlings, resulting in late results, mixed varieties, and low economic benefits, which brought serious economic losses to farmers
