Introduction to the key techniques of melon and vegetable field management in summer and winter

Melons and vegetables account for a large part of vegetables, such as cucumber, zucchini, pumpkin, cucumber, towel gourd, balsam pear and so on. However, melons and vegetables are easily affected by the weather, which is also a concern of many growers. Next, let's take a look at the introduction of the key points of melon and vegetable field management in summer and winter.

1. Introduction to the key techniques of melon and vegetable field management in summer.

1. Scientific use of fertilizer

Melons and vegetables have a large demand for fertilizer, and the consumption of fertilizer is relatively fast, so when growing melons and vegetables, ensuring adequate fertilizer supply is the guarantee to increase yield and quality. Fertilizer is rich in nitrogen, phosphorus, potassium and trace elements in the seedling stage, flowering stage, ripening stage and after harvest of melons and vegetables.

2. Watering to cool down

In the high temperature season, irrigation should be carried out according to the growth of soil and melons and vegetables to reduce soil temperature, environmental temperature and leaf temperature to avoid high temperature burning of leaves; it can also replenish water, dissolve fertilizer and promote plant growth and fruit.

3. Pick the heart at the right time

For melons and fruits such as eggplant, pepper and tomato, after receiving the first fruit, part of the center and paracentric can be removed according to the growth density, so as to eliminate the "apical dominance", so as to make the plant growth more balanced. so that nutrients are more concentrated in the young fruit, promote fruit growth and increase yield, rather than growing tall and bearing less fruit.

4. prevention and control of diseases and insect pests

In summer, growing vegetables are vulnerable to diseases and pests, such as anthrax, canker, aphids, tobacco insects and so on. And melons and vegetables as a common food in our daily life, food drug residues are also a big problem, so when growing melons and fruits, we should avoid using pesticides as far as possible, so as not to use them, and strictly prohibit the use of pesticides with high toxicity and long residual effect for a long time, in order to ensure food safety, in the first half of the harvest, no matter what insect pests can be used.

1. Cold prevention measures

In order to improve the surface soil temperature, plastic film can be covered to achieve the effect of heat preservation.

Plastic film or sunshade nets can be used as wind barriers to be laid in the north, northeast or northwest of the melon and vegetable fields.

If the temperature drops sharply, the plant is easy to freeze, especially in the seedling stage, the whole plant can be covered before the severe cold to prevent frostbite.

2. Rational fertilization

Generally choose the combination of organic fertilizer and chemical fertilizer, all kinds of nutrient elements should be balanced, like nitrogen, phosphorus, potassium and trace elements. Apply less nitrogen fertilizer before hanging fruit to avoid excessive nutrition and be more prone to frostbite. Potassium dihydrogen phosphate can be sprayed properly to enhance the stress resistance of the plant.
