No-tillage planting method of tomato in northern Suzhou intertidal zone saline-alkali soil

Abstract

The invention discloses a no-tillage planting method of tomato in northern Suzhou intertidal zone saline-alkali soil. The method comprises the following steps: a: on the basis of the saltness of a soil plough layer and the salt tolerance threshold value of fodder barley-tomato, determining a planting saline-alkali soil plot, and ploughing soil for 30cm to freeze upturned soil in winter; b: after fertilizer is applied, using a rotary cultivator to rotatably rake the plough layer for 20cm; c: planning fodder barley in spring to cover and manage a target plot; d: during April and May in spring, applying compound fertilizer, nitrogenous fertilizer and plaster as base fertilizer, and carrying out no-tillage planting of tomato seedlings; e: managing the tomato until the tomato is harvested; f: after the tomato is harvested, on the basis of ploughing the soil for 30cm to freeze upturned soil in winter, carrying out alternation of crops according to the steps b to e. The method organically combines the rotation planting agriculture with the physical, chemical and biological treatment measures of the saline-alkali soil, is a saline-alkali soil improvement mode jointly obtained by ecological, economic and social benefits and performs an active acceleration function on the modification of the northern Suzhou intertidal zone saline-alkali soil and the sustainable development of the agriculture.

Description

technical field [0001] The invention relates to the technical field of continuous agricultural transformation of saline-alkali land in tidal flats in northern Jiangsu, specifically a no-tillage saline-alkali land in tidal flats in northern Subei, which reduces production costs and improves production efficiency, promotes the upgrading of planting structures in saline-alkali lands, and enriches the industrial structure of tidal flat saline-alkali lands. How to grow tomatoes. Background technique [0002] Salinity-alkali stress is one of the most important stress factors affecting agricultural production and land productivity. According to incomplete statistics from UNESCO and FAO, 25% of the world's land area is affected by salinization. The area of ​​saline-alkali land in China is about 99.13 million hm 2 , accounting for 26.3% of the world's saline-alkali land area, which is widely distributed in coastal and inland areas, and most of the saline-alkali land has been under ...

Problems solved by technology

[0005] Physical, chemical, and biological improvement measures have their own advantages and disadvantages in treating tidal flat saline-alkali land. A single improvement measure has limited effect and high cost. High-efficiency cultivation of coastal tidal flat agriculture is a systematic project. It is necessary to comprehensively use physical, chemical and biological measures to achieve the purpose of controlling salt, improving soil, preserving seedlings and promoting growth
