Minyun cloud "before and after the rain, point melon seeds." After the rainy season, the outside temperature rises to the temperature level suitable for the open-air growth of vegetables. The majority of vegetable farmers also cultivate various open-field vegetables when they grab the farm. Before the planting of open field vegetables, priority shall be given to the following four aspects:
First, choose the environment
Around the place of production, we must avoid pollution sources such as chemical plants and ensure the safety of water, soil, and atmosphere. Avoid re-embarrassment, choose convenient transportation, convenient irrigation, fertile soil, high dry terrain, convenient drainage and irrigation plots.
Second, the soil fertigation
The general output of vegetables is higher and the demand for fertilizers is greater. To achieve high quality and high yields, it is necessary to ensure adequate supply of fertilizers. Pay attention to the application of base fertilizer, fully decomposed farmyard fertilizers, high-efficiency compound fertilizers, and biological bacterial fertilizers. It is necessary to increase the amount of nitrogen and potassium fertilizers for the production of leafy vegetables, the use of phosphorus and potassium fertilizers for fruit and vegetable vegetables, and the effect of microelement fertilizers such as molybdenum fertilizer, boron fertilizer and selenium fertilizer for the production of melons and vegetables. , can improve fruit quality, improve the flavor and taste of fruits. The fertilizer is spread evenly, the earthworms are smashed, the deep-rotational tillage, the leveling and flouring, and the ditching are to be sowed.
Third, choose strong seedlings
Strong seedlings are the basis for high yields, and they should choose age-appropriate seedlings when planting. Strong seedlings have strong resistance to stress, quick seedlings, strong ability to adapt to the outside environment, and high yields. It is necessary to decisively eliminate old seedlings, leggy seedlings, diseased seedlings, mechanical damage seedlings and other poor quality seedlings, so that excellent seed selection. To purchase seedlings, we must purchase planted vegetable nursery bases with high reputation, large scale, strong strength and guaranteed seed quality, and obtain invoices.
Fourth, timely planting
Colonization Select the morning of a week of continuous fine weather and cold-tailed morning head planting. Grasp suitable density according to planting species. After planting, timely planting water, the amount of water should not be too large, to prevent lowering the temperature, affect the slow seedlings. After the slow seedlings are over, they can be arbitrarily cultivated and moved into early management.
