Embodiment 1

[0029] Example 1 The following steps were taken to realize the rapid construction of macadamia nut early fruit and high yield gardens in the karst rocky desertification mountainous area of ​​Xingyi City, Guizhou Province:

[0030] (1) Site selection and site preparation: Select rock pits below 1000 m above sea level and above 50 cm in soil layer. Two months before planting, according to the exposed rock and soil layer conditions, dig irregularly in length and width according to the row spacing of 4.5 m×5.5 m 1. A planting hole with a depth of 60 cm×60 cm×50 cm. When digging the hole, stack the topsoil and subsoil separately, and remove the stones. After the weathered planting hole, sprinkle 250 g of quicklime around the wall and bottom of the hole, and then use 20 Mix 1 kg of decomposed poultry and livestock organic fertilizer, 50 g of soil water retaining agent and topsoil and backfill. Backfill the topsoil with the planting layer. When returning to the hole, the layers will b...

[0035] Example 2 The following steps were adopted to realize the rapid construction of macadamia nut early fruit and high yield garden in the karst rocky desertification area of ​​Baise City, Guangxi Zhuang Autonomous Region:

[0036] (1) Site selection and site preparation: Select rock pits below 1000 m above sea level and above 50 cm in soil layer. Two months before planting, according to the exposed rock and soil layer conditions, dig irregularly in length and width according to the row spacing of 4.5 m×6.0 m 1. A planting hole with a depth of 60 cm×60 cm×50 cm. When digging the hole, stack the topsoil and subsoil separately, and remove the stones. After the weathered planting hole, sprinkle 250 g of quicklime around the wall and bottom of the hole, and then use 20 Mix 1 kg of decomposed poultry and livestock organic fertilizer, 50 g of soil water retaining agent and topsoil and backfill. Backfill the topsoil with the planting layer. When returning to the hole, the layers wi...

[0041] Example 3 The following steps were adopted to realize the rapid construction of macadamia nuts in the karst rocky desertification mountainous area of ​​Xingyi City, Guizhou Province:

[0042] (1) Site selection and site preparation: Select rock pits below 1000 m above sea level and above 50 cm in soil layer. Two months before planting, according to the exposed rock and soil layer conditions, dig irregularly in length and width according to the row spacing of 4.5 m×5.5 m 1. A planting hole with a depth of 60 cm×60 cm×50 cm. When digging the hole, stack the topsoil and subsoil separately, and remove the stones. After the weathered planting hole, sprinkle 250 g of quicklime around the wall and bottom of the hole, and then use 20 Mix 1 kg of decomposed poultry and livestock organic fertilizer, 50 g of soil water retaining agent and topsoil and backfill. Backfill the topsoil with the planting layer. When returning to the hole, the layers will be solid. After returning to the ...

Abstract

The invention discloses a rapid construction method of a macadamia nut early-fruiting and high-yield garden in a karst rocky desertification mountain area and belongs to the technical field of fruit tree cultivation. The method comprises the following steps: selecting a land and carrying out soil preparation, selecting germchit, carrying out field planting on nursery stocks, carrying out tending management and shaping tree bodies. Specifically, the method comprises: selecting rock pits with the altitude of being lower than 1000m and a soil layer of being 50cm or more, and digging field planting holes; carrying out the soil preparation; selecting non-woven fabric nutrient bags grafted big seedlings as the germchit; carrying out the field planting on 3 to 5 macadamia nut varieties with relatively consistent florescence and fruit maturation period by adopting a mixed planting manner; combining water and fertilizer management and the like; topping when shoots of young plants grow to certain length every time, so as to promote the young plants to branch and culture early-fruiting and high-yield tree crowns. By adopting the method provided by the invention, the macadamia nut early-fruiting and high-yield garden is constructed in the karst rocky desertification mountain area; the garden enters an economic gain period one year ahead of a conventional grafted seedling garden; the investment period is shortened and the investment cost of constructing the garden is reduced; the recovery of vegetation covers of the karst rocky desertification mountain area can be facilitated, water and soil loss is prevented, people are led to a fortune and rocky desertification is managed.

Description

technical field [0001] The invention relates to the technical field of fruit tree cultivation, in particular to a method for quickly building macadamia nut early fruit and high-yield gardens in karst rocky desertification mountainous areas. Background technique [0002] Karst rocky desertification refers to the severe erosion of soil caused by the interference and destruction of unreasonable human social and economic activities in the context of subtropical karst regions, with large areas of exposed bedrock, severe decline in land productivity, and land degradation similar to desert landscapes on the surface. process. At present, more than 70% of rocky desertification disasters in China are mainly distributed in 8 southern provinces (districts, cities) including Guizhou, Yunnan, Guangxi, Hunan, Hubei, Chongqing, Sichuan, and Guangdong. Among them, Guizhou is located in the karst center of Southwest China. It is the province with the largest distribution area and the most se...
