Problems solved by technology

Moreover, it will also cause the growth of pathogens and increase root diseases. For example, acidification of the soil will aggravate the growth and spread of root nematode diseases of crops, etc.
[0009] Hazard 2: Acidic soil will cause the fixation of nutrient elements. For example, when the pH value of the soil is lower than 6, the fixation rate of phosphorus in red soil will rise linearly with the decrease of pH, which will greatly reduce the effective utilization rate of phosphorus and become an impact on agriculture. one of the serious problems of development

Embodiment 1

[0044] Such as figure 1 As shown, on January 24, 2019, passion fruit seedlings were planted in the acidic red soil area with the following methods:

[0045] (1) For each fruit seedling, dig an earth pit with a diameter of 30 cm and a depth of about 10 cm on the ground, and fill it up with the organic fertilizer made in this case;

[0046](2) Plant the fruit seedlings in the center of the pit, bury the lower part of the plant in the soil about 4-5 cm, and apply a layer of thin soil about 1 cm thick on the surface of the pit;

[0047] (3) When planting for the first time, it should be fully watered, and the soil should be drenched. The standard is to fully infiltrate the fertilizer pit; 200L or more irrigation is better;

[0048] (4) After that, it can be planted according to conventional management.

[0049] The original planting method of the land is:

[0050] Apply other organic fertilizers and mixed soil. Because the local soil is strongly acidic, it cannot be planted dir...

Embodiment 2

[0053] On February 23, 2019, Beilingwei Village, Leizhou City, Zhanjiang was used as the experimental site. The current situation of the land: crops with normal economic value cannot be planted; the purpose of the experiment: eucalyptus seedlings were successfully planted on the acidic red soil soaked in seawater.

[0054] Such as image 3 As shown, the experimental group uses the method of the present invention to directly pour the organic fertilizer of livestock and poultry manure into a deep 10-15cm, and in the fertilizer pit of 50cm in diameter, pave it flat, directly plant it into the sapling, cover the surface with a thin layer of soil, and then cover a Layer dead leaves or dead branches are pressed down; Simultaneously with the eucalyptus seedlings that do not adopt the method of the present invention to plant as contrast group, observe on March 10th and March 18th, 2019, as Figure 4 with 5 Shown, it can be seen that the saplings of the comparative ratio group on Marc...

Abstract

The invention provides a technology for directly planting economic crops on acid red soil. The technology includes the steps: (1) preparing livestock manure organic fertilizers for standby applicationby taking livestock manure as a raw material by a field edge fermentation method; (2) digging soil pits on the ground by each seedling, and filling the soil pits with the organic fertilizers; (3) planting the seedlings at the centers of the pits, embedding the lower portions of plants into the organic fertilizers, applying a layer of laminated soil to the surface of each fertilizer pit, sufficiently watering the plants in first planting, drenching the soil and taking sufficient infiltration of the fertilizer pits as the standard; (4) managing planting according to conventions. The survival rate and the growth quality of the plants can be remarkably improved, planting materials and labor cost are remarkably reduced, crops can be directly planted on the acid red soil technically, and red soil improvement and planting income increase are synchronously achieved.

Description

technical field [0001] The invention belongs to the technical field of planting, in particular to a technique for directly planting economic crops on acidic red soil. Background technique [0002] Acidic soil is the general term for soil with a pH value less than 7. Including brick red soil, red soil, red soil, yellow soil and dry red soil and other soil types. From a global perspective, acidic soils are mainly distributed in two major regions, one is tropical and subtropical regions, and the other is temperate regions. The acidification problem in Northern Europe and North America mainly occurs on podified soil, while the acidic soil in my country is mainly distributed in the vast tropical and subtropical regions south of the Yangtze River and Yunnan, Guizhou, Sichuan and other places, with an area of ​​about 2.04×10 8 hm 2 , mainly concentrated in Hunan, Jiangxi, Fujian, Zhejiang, Guangdong, Guangxi, and Hainan. The pH value of most of the soil is less than 5.5, a large...
