Method for improving old vegetable field

Abstract

The invention relates to a method for improving an old vegetable field. Due to years of vegetable planting, garden soil aging, descending land capability and increasingly severe disease and pest at present, the economic benefit per unit area descends. The method is realized in the following steps: applying more farmyard manure, increasing humus, adopting different fertilizers, and planting different families (species) of vegetables in a crop rotation mode to improve the soil and avoid shortage of a certain element in soil; and in addition, intermingling high and low plants in the vegetable field, thereby improving the soil, reducing the disease and pest and increasing the planting benefit. The ditches around the vegetable garden must be matched smoothly, thereby facilitating drainage and irrigation, lowering the groundwater level and benefiting the well growth of the root system. Meanwhile, the management techniques, such as ground surface cover and the like, are adopted to prevent water and soil erosion, cultivate the aftereffect of soil and strive for good harvest all the year.

Description

technical field [0001] The invention relates to land improvement and cultivation technology, in particular to a method for scientific improvement and fertilization of old vegetable fields. Background technique [0002] Since vegetables have been planted in vegetable fields for many years, the soil quality is aging, soil fertility is declining, and pests and diseases are also serious year by year, and the economic benefits per unit area are declining. Contents of the invention [0003] 1. To improve the soil of old vegetable fields, it is necessary to apply more farmyard manure and increase humus, so that the factors such as water, fertilizer, air, heat, and bacteria in the cultivation layer can be coordinated and unified, and a suitable temperature, humidity and fertilizer can be created for the growth of vegetable roots, stems and leaves. Complete and excellent environment. [0004] 2. Choose chemical fertilizers and improve them in a targeted manner. Because the acidity...
