Fertilizer-reducing efficiency-increasing processing tomato cultivation method applicable to saline-alkali soil in Xinjiang

Abstract

The invention relates to a fertilizer-reducing efficiency-increasing processing tomato cultivation method applicable to saline-alkali soil in Xinjiang. The fertilizer-reducing efficiency-increasing processing tomato cultivation method applicable to the saline-alkali soil in Xinjiang includes the steps of (1) fertilizing according to the pH values of the soil and irrigation water; (2) applying a basic fertilizer according to the soil salinity; (3) transplanting greenhouse tomatoes from April to early May; (4) controlling the watering time and frequency, namely performing under-mulch pressurizeddrip irrigation and stopping water 15 days before picking; (5) fertilizing, namely applying a seedling emergence fertilizer at the beginning of June, and performing drip irrigation, so that the processing tomatoes are in the squaring stage before primary formal irrigation and fertilization according to a tomato growth period; (6) determining the consumption quantity of the fertilizers according to indexes detected every time when in the squaring stage, the flowering stage and the fruiting stage as well as the diameter of the tomatoes reaches 6 centimeters. The fertilizer-reducing efficiency-increasing processing tomato cultivation method applicable to the saline-alkali soil in Xinjiang can reduce consumption of the fertilizers, directly lower costs, increase the income, improve the technological level of regional modern agricultural production and increase both production and income for farmers.

Description

Technical field [0001] The invention belongs to a cultivation method for processed tomatoes in Xinjiang, in particular to a weight-reducing and efficiency-increasing cultivation method for processed tomatoes suitable for saline-alkali soil in Xinjiang. Background technique [0002] Xinjiang's processed tomato production occupies a quarter of the global market share and is one of Xinjiang's pillar industries. The total area of ​​cultivated land in Xinjiang's irrigation area is 75.77 million mu, and the area of ​​saline-alkali cultivated land is 24.3 million mu, accounting for 32.07% of the cultivated land. Among them, the severe accounted for 4.44% of the saline-alkali farmland area, the moderate accounted for 19.60%, and the mild accounted for 75.85%. The soil in Xinjiang is heavy in salinity. According to surveys, 86% of the soil in Xinjiang is low in salt, 89% is strongly alkaline, 80% of the soil is deficient in nitrogen, 91% of the soil is deficient in potassium, and the pho...

AI Technical Summary

Problems solved by technology

At the same time, in actual operation, the application of fertilizers must be uniform, there is a certain degree of uncertainty, and it is difficult to promote

There have been domestic reports on the application of tomato-specific fertilizers in processing tomatoes, but there have been no reports in the literature on the systematic research on high-yield cultivation techniques for processing tomatoes under the condition of drip irrigation in saline-alkali soil in Xinjiang.
