The summer vegetable production is in a hot season, with poor production conditions and a high risk of planting. It is often difficult to obtain higher returns. The seedlings of this quail vegetable are generally in May and June, and the harvest period is July and August. This season is the rainy season in the northern region. This period is the highest period in one year's temperature, and it is also prone to extreme weather such as high temperature and drought, heavy rain, etc. The production of vegetables at this stage is difficult to manage, and it is easy to cause various pests and diseases. The loss rate of vegetables is high. Especially in the case of heavy rain or continuous rainy weather, vegetables tend to rot, deteriorate, and their quality deteriorates. Directly affect the income of vegetable farmers.
For this reason, it is recommended that vegetable farmers make comprehensive considerations when selecting vegetable varieties and weigh them all. The vegetable varieties planned to be cultivated shall have vegetable varieties that are resistant to high temperature and drought, have strong ability to resist diseases and pests, have a relatively strong market demand, are easy to transport, and have less difficulty in field management. Such as fresh green onions, beans, summer cucumber and other vegetable varieties. In addition, according to the local market demand, we can flexibly arrange some vegetable varieties with short growth period and the market demand in summer, such as coriander, spinach, fennel, garland chrysanthemum, etc., which are resistant to diseases and insect pests. Dishes should be selected from high-temperature drought-resistant, fast-growing, high-yield, and good-quality imported foreign vegetable varieties.
As vegetables grow more and more in summer, due to higher outside temperature and faster vegetable growth, there is more demand for water and fertilizer, and sufficient water and fertilizer supply must be ensured during the prosperous period. Due to high temperature and high humidity, it is also easy to induce a variety of pests and diseases. In addition to strengthening field management and cultivating strong seedlings, it is also necessary to do preventive work on pests and diseases as early as possible. Can cover shade nets, hang yellow panels, ground laying of crop stalks and other methods to reduce the incidence of pests and diseases, improve the quality of vegetables, increase vegetable output, achieve higher prices for better quality, yield bumper harvest.
