Problems solved by technology

With the continuous development of protected cultivation, vegetable production is further scaled and specialized, a single farming system and crop varieties, and excessive pursuit of economic benefits such as yield and excessive application of chemical fertilizers blindly lead to low soil fertilizer utilization rates and poor ecological environment quality. Decline, serious plant diseases and insect pests, etc., have seriously restricted the sustainable development of the high-efficiency facility vegetable industry, and continuous cropping obstacles have become one of the key issues that need continuous attention in facility vegetable production

Embodiment 1

[0046] In 2014, the scientific research team of Yangzhou University first put this idea into practice and explored the inner mechanism in depth. Researchers compared and analyzed the yield of water spinach under two kinds of water treatment and conventional dry planting, and the change of soil EC value before and after different soil layers. The variety of water spinach tested was Thai willow leaf water spinach. In March 2014, the soil was prepared in the greenhouse of the aquatic vegetable field of Yangzhou University. Use a rotary tiller to deeply plow the land in the shed. The depth of the plowing layer should be 30cm, and no base fertilizer should be applied. Use a ridger to make a furrow, set the height of the furrow surface to 15cm and width to 1.8m.

[0047] Sow at a high density of 2-3cm between plants on the furrow surface. Just moisten the furrow surface after sowing, the temperature should be kept at 15-18°C, and the seedlings will start to emerge after about 4-5...

Embodiment 2

[0050] In March 2021, led by Jiangsu Provincial Agricultural Technology Promotion Center and Yangzhou University College of Horticulture and Plant Protection, the implementation of the "rotational control and replacement" facility vegetable full-process green, high-quality and efficient production technology demonstration site-Huacheng Vegetable Base in Lishui District, Nanjing, Try planting water spinach wet-planted vegetables, and implement the "wet-dry rotation" model in order to achieve soil restoration, high-quality and high-yield crops.

[0051] Wet-grown vegetables were grown in multi-span greenhouses that had been planted continuously for 8 years and had serious soil salinization. Water spinach (Thailand willow leaves) was sown on March 12. Cultivate and manage according to the early spring and early rotation mode. The production method is as follows: Due to the heavy salinization of the soil in the facility, on February 5, the method of washing salt with water was us...

Abstract

The invention discloses a wet and dry crop rotation method for annual cultivation of vegetables in a protected land. With adoption of the wet and dry crop rotation method for annual cultivation of vegetables in the protected land, crops suitable for wet cultivation and xerophyte vegetables are cultivated in turn in the facility protected land. According to the method, the crops suitable for wet cultivation and the xerophyte vegetables are cultivated in turn in the facility protected land, the cultivation problems of soil salinization, nutrient imbalance, enzyme activity reduction, crop continuous cropping obstacles and the like in protected land cultivation are solved, and the purposes of reducing fertilizer and pesticide and improving quality and efficiency of the protected land are achieved.

Description

technical field [0001] The invention belongs to the technical field of plant cultivation, and in particular relates to a wet-dry crop rotation method for annual cultivation of vegetables in protected areas. Background technique [0002] Jiangsu Province is a major vegetable production province in the country, and it is also one of the advantageous areas for winter and spring vegetable production in the country. The green vegetable industry is one of the eight 100-billion-level agricultural characteristic industries that the provincial government has focused on. In 2019, the province’s vegetable planting area (including melon) was about 21.5 million mu, and the vegetable output was 55.2 million tons, accounting for 7% of the country’s total vegetable output. %, ranking fourth in the country. The average growth rate in the past five years has exceeded 5%. The coverage rate of improved vegetable varieties is more than 90%, and the proportion of vegetable facility production i...
