Embodiment 1

[0041] This example was carried out at the Shuguang Experimental Station in Linhe District, Bayannaoer City, Inner Mongolia. The local area has a temperate continental climate, with an annual average temperature of 6.8°C, an annual average precipitation of 140mm, long sunshine hours, large temperature difference between day and night, and annual sunshine hours of 3229.9h. The frost-free period is about 140 days. The soil texture of the test site is sandy loam with a bulk density of 1.58g / cm 3 , the field water holding rate is 0.22, and the groundwater depth is about 1.8m. The tomato variety for planting and processing is Shitun No. 2. It is an early-maturing and processing tomato first-generation hybrid prepared by using the inbred lines N-375 and N-47 of the imported and processed tomato varieties from the United States. It is a self-capping, early-maturing variety. According to the control method proposed by the present invention and the value range of the control target, c...

Embodiment 2

[0068] This embodiment was carried out at Shuguang Experimental Station in Bayannaoer, Inner Mongolia. The soil texture of the test site is sandy loam. The tomato variety for planting and processing is Shitun No. 2. According to the control method proposed by the present invention and the value range of the control target, combined with the actual natural climate conditions of the local test station, the saline-alkali land processing tomato film-covered brackish water drip irrigation method of this embodiment is finally determined as follows:

[0069] (1) Cultivation method

[0070] Wide rows and high ridges were used for planting. In April 2014, the ridges were artificially raised and covered with white plastic film. The shoulder width of the ridge was 0.9m, the height of the ridge was 0.30m, the length of the ridge was 20m, and the distance between the centers of the furrows was 1.5m. On May 20, seedlings were transplanted in plug trays, and two rows of tomatoes were plant...

Abstract

The invention provides a saline-alkali soil brackish water film mulching drip irrigation processing tomato planting method, which comprises the following steps: (1) planting processed tomatoes: planting the processed tomatoes by adopting a manner of wide rows and high ridges, and mulching a white film above plants; (2) laying out a drip irrigation system, wherein an interval b between the drip irrigation systems is 48 to 52 cm; an interval a between drip emitters is 0.25 to 0.35 m; (3) carrying out high-frequency and small fixed amount water irrigation in a growing period of the processed tomatoes: alternatively irrigating brackish water and fresh water, and adopting the fresh water for irrigation in a seedling stage, and no irrigation in a red-mature period. The invention puts forward a cultivation method taking the brackish water and saline-alkali soil as targets in combination with the realities of shortage of fresh water resources, abundant underground brackish water resources and serious soil salinization in an arid region and a semi-arid region, and not only moisture is enabled to be held up within a field microcirculation of soil-and-film, deep seepage losses of the moisture are greatly reduced, but also under-film soil evaporation is remarkably lowered, sources of soil secondary salinization are cut off and the surface accumulation of salt is eliminated.

Description

technical field [0001] The invention belongs to the field of agriculture, and in particular relates to a method for planting vegetables by using film covering and drip irrigation techniques based on the development and utilization of inferior water. Background technique [0002] Soil salinization has become a global problem, and the area of ​​saline-alkali soil in my country is about 24.6 million hm 2 , cultivated land salinization 7.6 million hm 2 , about 1 / 5 of the cultivated land is salinized. Reasonable and efficient development of saline-alkali land is of great significance to improving land productivity, improving the ecological environment, and ensuring food security in my country. However, a large amount of salt ions contained in saline-alkali soil will hinder the normal growth of plants and the absorption of nutrients and water through salt stress, ion poisoning, etc., resulting in plant failure and low yield. A large number of scientific researchers have tried t...
