Embodiment 1

[0044] Embodiment 1 A kind of method that adopts the nutrient soil containing conifer fallen leaves organic matter to carry out original soil cultivation on mild saline-alkali land

[0045] Include the following steps:

[0046] A. Select land to build seedbeds

[0047] Choose mild saline-alkali land with deep soil layer, among them, sandy soil with soil salt content of 0.11%-0.16%, soil pH of 7.5-8, and soil organic matter content of 5.2-6.4mg / kg; apply sufficient base fertilizer, tillage, After raking, make a furrow. The height of the furrow is 20-35cm, the width is 2-3m, and the length is 3-5m. Then, an arch shed is built, and the outer layer is sealed with a plastic film after being closed with a black shade net.

[0048] B. Seedbed treatment

[0049] From March 10th to 15th, spread a layer of nutrient soil on the seedbed with a thickness of 10-15cm, plow 30cm, and then water the bed with soil fungicide 11kg / mu at the same time to sterilize the soil on the seedbed;

Abstract

The invention provides a method for carrying out original soil cultivation on mild saline-alkali soil through needle-leaved tree fallen leaf organic matter containing nutrient soil. The method comprises the step of applying the nutrient soil. The nutrient soil is prepared from 36-41 parts of lotus pond sludge, 35-47 parts of needle-leaved tree fallen leaf containing organic matter, 11-17 pats of nitrogen-phosphorus-potassium mixed fertilizer, 13-26 parts of chestnut shell powder, 13-28 parts of phosphorus feldspar, 5-11 parts of naringin, 1-5 parts of citric acid, 6-13 parts of sesame paste residues, 8-14 parts of walnut meal, 4-9 parts of muddy papaya flesh, 2.5-7.5 parts of codfish powder, 14-22 parts of composted rabbit dung, 1-5.5 parts of water-retaining agent and 0.4-1.7 parts of microelements. The invention further provides a preparation method of the nutrient soil. According to the planting method, the cost for carrying new soil is saved, cost is reduced, the cost is reduced by 35%, the functions of increasing the soil organic matter content and reducing soil ion exchange capacity are achieved, and the seedling survival rate of planted five-leaved pines reaches up to 95.8% to 97.1%.

Description

technical field [0001] The invention relates to a method for in-soil cultivation of mild saline-alkali land by using nutrient soil, in particular to a method for in-soil cultivation of mild saline-alkali land by using nutrient soil containing fallen leaves of conifers, and belongs to the technical field of in-soil cultivation in saline-alkali land. Background technique [0002] According to statistics, there are still about 260 million mu of potentially salinized soil in China. If such soils are improperly exploited, irrigated and cultivated, secondary salinization will easily occur. [0003] There are 100 million hectares of saline-alkali land in my country, and the improvement of saline-alkali land is a worldwide problem. Saline-alkali land is a part of my country's important land resources, and saline-alkali soil occupies a large proportion of wasteland resources. [0004] Saline-alkali soil includes two kinds of soils with different properties: saline soil and alkaline...
