Problems solved by technology

Since Jerusalem artichoke is generally sown in March-April, field crops (such as winter wheat, rapeseed, etc.) have not been harvested during this period. If the land is idle in winter, resources will be seriously wasted. Seriously restricting the quality of sowing, resulting in unbalanced growth of Jerusalem artichoke and serious reduction in production

Embodiment 1

[0021] In 2011-2012, the test of rape interplanting South Jerusalem artichoke No. 9 was carried out in the test base of Jiangsu Dafeng Saline Land Agricultural Science and Technology Co., Ltd. The saline-alkali land cultivation layer (0-20cm) has a salt content of 3‰-9‰, sowing Jerusalem artichoke seed pieces 50 days before the rapeseed harvest (June 3rd) (April 15th), and harvesting rapeseed on the 50th day after sowing, Fertilization and weeding with herbicides were carried out on the 74th day after sowing, and on the 80th day after sowing, the inner and outer three ditches were completely excavated and cleaned. The Jerusalem artichoke seed block is interplanted at 85kg / mu, and the average size of the seed block is 38g. The planting density of Jerusalem artichoke per acre is controlled at 2230 plants. Before planting, 40kg of compound fertilizer (nitrogen, phosphorus, and potassium content are respectively 15‐18‐12) is applied per mu, and the roots are mulched when the tuber...

Embodiment 2

[0023] In 2012-2013, the experiment of rapeseed interplanting South Jerusalem artichoke No. 9 was also carried out at the test base of Jiangsu Dafeng Saline Land Agricultural Science and Technology Co., Ltd. The saline-alkali soil cultivation layer (0-20cm) has a salt content of 4‰-8‰, sow Jerusalem artichoke seed blocks 60 days before the rape harvest (June 8) (April 10), and harvest the rapeseed on the 60th day after the inter-sowing. Fertilization and weeding with herbicides were carried out on the 80th day after sowing, and on the 85th day after sowing, the inner and outer three ditches were completely excavated and cleaned. The Jerusalem artichoke seed block is interplanted at 88kg / mu, and the average size of the seed block is 41g. The planting density of Jerusalem artichoke per acre is controlled at 2150 plants. Before planting, 38 kg of compound fertilizer (nitrogen, phosphorus, and potassium content are respectively 15‐18‐12) is applied, and the roots are mulched when ...

Abstract

The invention discloses a method for cultivating Helianthus tuberosus by means of interplanting the Helianthus tuberosus and oilseed rapes on saline-alkali lands. The method includes interplanting Helianthus tuberosus seed tubers 40-60 days before the oilseed rapes are harvested; harvesting the oilseed rapes in 40-60 days after the Helianthus tuberosus seed tubers are interplanted; applying fertilizers and killing weeds by the aid of weed killers in 70-80 days after the Helianthus tuberosus seed tubers are interplanted; comprehensively digging and cleaning three inner furrows and three outer furrows on each land in 80-90 days after the Helianthus tuberosus seed tubers are interplanted; harvesting the Helianthus tuberosus in 225-250 days after the Helianthus tuberosus seed tubers are interplanted. The method has the advantages that the Helianthus tuberosus seed sowing time can be won on the non-idle lands in winters, accordingly, early germination and fast growth of the Helianthus tuberosus can be promoted, and the lodging resistance can be improved; non-tillage cultivation effects can be realized, the method is beneficial to improving physical and chemical properties of soil of the saline-alkali lands, the fertility of the soil can be improved, and saline-alkali per-mu comprehensive economic output can be increased.

Description

technical field [0001] The invention relates to a technique for cultivating Jerusalem artichoke, in particular to a cultivation method for inter-sowing Jerusalem artichoke in saline-alkali land. Background technique [0002] According to the incomplete statistics of UNESCO and FAO, the area of ​​saline-alkali land in the world is 954 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 national arable land area. Saline-alkali soil refers to those soils with high salt content and pH greater than 9, which make it difficult to grow plants, especially crops. According to the amount of salt and alkali contained, it can be further divided into mild (0.1%-0.25%), moderate (0.25%-0.5%) and severe saline-alkali land (0.5%-0.6%). The salt in the saline-alkali soil is very harmful to the root system of the plant. After the root system of the plant is poisoned by salt, the root system will be poo...
