1. 1 Understand the planting area.

Before planting pollution-free vegetables, it is necessary to investigate the planting area in advance, and fully understand the soil conditions and environmental conditions to ensure that it can meet the implementation requirements of pollution-free vegetable planting technology and the growth needs of such vegetable crops, so as to avoid adverse effects on the normal growth of vegetables.

1.2 do a good job of soil preparation

Remove the waste, sundries and plant roots around the planting area and in the land to ensure the overall efficiency and quality of land preparation and provide a good planting area for pollution-free vegetables.

1.3 check the planting area

If the pollution-free vegetable planting technology is integrated into the traditional vegetable planting area, the actual planting conditions should be checked to ensure that the planting area can meet the planting needs of pollution-free vegetables, and the trial planting work should be carried out in advance to ensure that the experiment is correct, and then large-scale planting should be carried out to avoid quality problems in the planting process of pollution-free vegetables.

2. Do a good job of pre-planting treatment.

Before planting, it is necessary to make clear the varieties of pollution-free vegetables, ensure the disease resistance and insect resistance of seeds during the selection process, and select high-quality pollution-free vegetable seeds for planting. In addition, after selecting the seeds, the relevant personnel should also soak the seeds in a reasonable proportion of drugs, and then sterilize the seeds by exposing them to the sun, thus reducing the probability of pests and diseases during planting and ensuring the healthy growth of pollution-free vegetables.

3 scientific selection of planting methods

3. 1 Guarantee the quality of vegetables

Because pollution-free vegetables have high requirements on the external environment and surrounding climate in the process of seed selection, sowing and planting, environmental and climate protection can improve the quality of vegetable planting. It is necessary to choose scientific planting methods before planting, and combine the surrounding environment and climate conditions to ensure that the planting methods can be compatible with the growth conditions of pollution-free vegetables.

3.2 Planting stage

In order to ensure the planting quality of pollution-free vegetables, we should fully grasp the growth characteristics of different vegetables and find out the best time for planting. In the process of planting, we should avoid carrying out related work in the period of high incidence of pests and diseases; In the high temperature period in summer, it is necessary to strengthen the disaster risk prevention of vegetables to avoid reducing the survival rate of vegetables due to external influences, and then bring greater economic losses to the agricultural industry.

3.3 Different vegetable planting methods

For the vegetables of flood and drought, under normal circumstances, the method of rotation planting can be used to ensure the quality of vegetables; For leafy vegetables, intercropping and rotation can be used organically. In addition, for melon vegetables, it is necessary to rotate once a year; For shallow-rooted and deep-rooted vegetables, rotation can be directly used to carry out planting work.
