Method for cultivating macadimia nuts on karst rock-desertification mountain land

Abstract

The invention relates to a method for cultivating macadimia nuts on karst rock-desertification mountain land. The method comprises the steps of variety breeding, soil preparation, seedling culture and grafting, planting, pruning, water and fertilizer management and disease and pest control. Disease and pest control is conducted in the way of adopting an agentia obtained by mixing thiophanate methyl with probenazole for spray control, the mass ratio of thiophanate methyl to probenazole in the agentia is (5-8):1, and the mass percentage of thiophanate methyl and probenazole in the agentia is 60-70%. The agentia is diluted by 500-800 times to be sprayed onto the earth surface and branches, leaves and fruits of macadimia nuts once every other 10-15 days. By using macadimia nuts as pioneer tree species to achieve barren mountain afforestation, wind prevention and soil fixation, the ecological environment of karst rock-desertification mountain land can be recovered, and income of local farmers can be increased.

Description

technical field

[0001] The invention relates to a method for cultivating economic plants, in particular to a method for cultivating macadamia nuts in karst rocky desertification mountains. Background technique

[0002] Macadamia nuts (Latin name: Macadamia ternifolia F.), also known as macadamia nuts, belong to the family Longanaceae. Among the many dried fruits, macadamia nuts have the highest economic value and have always enjoyed the reputation of "the king of dried fruits". Macadamia nuts are milky white, nutritious nutritious, oil content is about 70%, protein 9%, contains 17 kinds of amino acids including 8 kinds of amino acids necessary for human body, and is also rich in minerals and vitamins. In addition to making dried fruit, macadamia nuts can also be used to make pastries, chocolate, cooking oil, cosmetics, etc. After the peel is crushed, it can be mixed with livestock feed, and the shell can be used to make activated carbon or fuel, and it can also be crushed a...

[0016] A method for cultivating macadamia nuts in karst rocky desertification mountains, comprising the following steps:

[0017] (1) Variety selection: Select local drought-tolerant and barren-resistant nut tree species for breeding to obtain an excellent macadamia nut variety suitable for rocky desertification mountainous areas. After screening and breeding, a new variety "Guire No. 1" was obtained. The invention adopts the OC macadamia variety as the rootstock, and the variety "Guire No. 1" independently bred by Guangxi South Subtropical Agricultural Science Research Institute as the scion. OC has strong adaptability to the red soil in Guangxi, with well-developed root system, tolerance to barrenness, vigorous growth, but many horizontal branches, small and thin leaves, and low leaf yield. "Guire No. 1" has strong resistance to drought and cold, and is suitable for popularization and application in arid areas such as Guangxi, Yunnan, and Guangdong. Therefore, OC was used a...

[0025] Example 2: Indoor toxicity determination of thiophanate-methyl, allylbenzothiazole and their compound against macadamia nut powdery mildew

[0026] Test method: After pretesting to determine the effective inhibitory concentration range of each agent, thiophanate-methyl, allylbenzothiazole and their mixed preparations were serially diluted to 5 concentrations according to the active ingredient content gradient, and sterile water was used as a control. Refer to the "Pesticide Indoor Bioassay Test Guidelines for Fungicides", and use the mycelium growth rate method to determine the toxicity of the pesticides to macadamia nut powdery mildew. After 72 hours, the diameter of the colony was measured by the cross method, and the net growth and mycelial growth inhibition rate of each treatment were calculated, and the regression formula of toxicity was obtained, and the EC was calculated. 50 .

[0033] (1) Experimental design:

[0034] 4 treatments were set up in the test, and each treatment group had 3 repetitions, a total of 12 plots were randomly arranged, and the area of ​​the plot was one mu. The medicines and dosages corresponding to each treatment are as follows:

[0035] Test group 1#: 60% thiophanate-methyl allylbenzothiazole wettable powder (ratio 5:1), dilution factor 800 times
