Problems solved by technology

The improvement and treatment methods of saline-alkali land mainly provide a full range of methods, applying soil subsoiling agent and saline-alkali soil amendment to the deeply loosened soil, formulating microbial organic fertilizer according to the detected soil components, and adopting the nutrient balance method And nitrogen, phosphorus and potassium ratio method: reduce the amount of soil fertilizer supplied by the amount of fertilizer required for the target output, and the difference is supplemented by fertilization, and then plant green manure-salt-alkali-tolerant high-yield feed

Embodiment 1

[0020] Example 1: The geographical location of the test area is between 32°59′30″ ~ 33°0′31″N, 120°49′40″ ~ 120°51′4″E, about 4 km away from the Yellow Sea in the east, and adjacent to the Dafeng Elk National Level in the west. The nature reserve, which is located in the northern subtropical monsoon climate zone, has obvious transitional, oceanic and monsoonal characteristics. Choose to carry out on saline soil with a salt content of 5.7‰wt ~ 7.2‰wt. The experimental variety was South Jerusalem artichoke No. 1. When sowing, level the land, apply potassium sulfate compound fertilizer, apply 40 kg per mu, sow density 25cm×50cm, and plant the Jerusalem artichoke seed block with a weight of 40g. Ridge planting with a height of 15cm. Return the leaves as a whole to increase soil vegetation coverage and organic matter content, cut off soil capillaries, prevent saline-alkali land from returning to salt in winter and spring, and control the salt content of the soil cultivation laye...

Embodiment 2

[0022] Example 2: The geographical location of the experimental area is located in the saline-alkali land of the 149th regiment of the Xinjiang Construction Corps, with an average altitude of about 300-500 m. It is a typical temperate continental climate with long and severe winters and short and hot summers. The annual average temperature is 7.5-8.2 °C and the sunshine is 2318-2732 h, the frost-free period is 147-191 days, the annual rainfall is 180-270 mm, and the annual evaporation is 1000-1500 mm. Choose to carry out on saline soil with a salt content of 6.1‰wt ~ 7.8‰wt. The experimental variety was South Jerusalem artichoke No. 1. When sowing, level the land, apply potassium sulfate compound fertilizer, apply 40 kg per mu, sow density 25cm×50cm, and plant the Jerusalem artichoke seed block with a weight of 40g. Ridge planting with a height of 15cm. Return the leaves as a whole to increase soil vegetation coverage and organic matter content, cut off soil capillaries, pr...

Abstract

The invention provides an application of Jerusalem artichokes on improving a saline and alkaline land. The Jerusalem artichoke is the south Jerusalem artichoke No.1 and the steps for improving are as follows: planting the Jerusalem artichokes on the saline and alkaline soil with the salt content of 0.5-0.8 wt%; sowing seeds in the first year: flattening the land; applying potassium sulfate compound fertilizer; after the Jerusalem artichokes grow ripe, wholly returning roots, stems and leaves of the Jerusalem artichokes back to the field; farming the saline and alkaline land in the second year: after the Jerusalem artichoke germinates and grows until the length is 15-25 cm, thinning; controlling an acre number to 4800-5200 plants and applying 30-35 kilograms of potassium sulfate compound fertilizer into each acre, wherein the others are the same as the farming of the first time; farming the land in the third year: repeating the farming method of the second year to finish the improvement of the soil. The south Jerusalem artichoke No.1 provided by the invention has the advantages of strong adaptability and wide distribution area, and can be applied in the saline and alkaline land soil of northeast China, Inner Mongolia, Hebei, Shandong, Gansu, Shaanxi, Jiangsu and the like to improve the local saline and alkaline lands.

Description

[0001] technical field [0002] The invention belongs to saline-alkali land improvement and planting technology in agriculture and forestry, and specifically relates to a soil salt control method for planting Jerusalem artichoke on saline-alkali land with a salt content of 5‰-8‰. [0003] Background technique [0004] Saline-alkali land is a type of soil widely distributed on the earth and an important land resource. It means that the salt contained in the soil affects the normal growth of crops. According to incomplete statistics from UNESCO and FAO, the saline-alkali land area in the world is 954.38 million hectares, accounting for 10% of the arable land area, of which 99.13 million hectares is in my country, accounting for about 25% of the country's arable land area. The problem of land salinization is closely related to human activities. It not only causes the destruction of resources and the huge loss of agricultural production, but also poses a threat to the biosphere...
