Watermelon planting technology and pesticides, what is the best pesticide to grow watermelon

Watermelon cultivation in the open field is cultivation without protective equipment. The climate varies greatly from place to place, so the sowing time is also different, the southern region is sowing early due to the higher temperature, while the northern region is generally sown later, but the early cultivation time can also be correspondingly early. In spring open-field direct seeding, the appropriate time for open-field sowing is generally when the local final frost has passed and the ground temperature is stable at about 15.

The best time to sow seeds should also be determined according to conditions such as variety, cultivation season, cultivation method, and consumption season.

2 Seed treatment and germination: 1) Seeding: Dry seeds in the sun for two noons to improve the germination ability of seeds.

2) Soak seeds: soak the sun-dried seeds in warm water (about 30) for 6 hours, then take out the seeds and wrap them with a towel or coarse cloth to rub off the mucous membrane on the seed skin, soak them in 800 times the liquid of 60% Fu or 70% Fu methion-methyl sulfur wettable powder for another 4 hours, take out and rinse the liquid with water, which can prevent blight.

3) Germination: Put the soaked seeds flat on a wet towel, cover the seeds with a layer of wet towel, and put them at a constant temperature of 33 to promote germination (wash them again with water when they do not germinate for 24 hours).

3 Preparation before broadcasting:

1) Land selection: To cultivate watermelon, choose a plot with loose soil, good air permeability, drainage and easy transportation. Watermelon fields cannot be cropped continuously, and generally rotate once every 5 or 6 years. Otherwise, the blight is severe.

2) Stubble selection: the previous stubble has a great impact on the yield, quality and disease resistance of watermelon, and a good stubble can improve the yield and quality, increase the disease resistance, and lay the foundation for a bumper yield and harvest. The best stubble for cultivating watermelon is wasteland, followed by the second wasteland and cereal crop stubble, soybean stubble and vegetable land are not ideal, and melon stubble can not be planted continuously.

1. Seedbed treatment.

Main pest control: blight, cataplexy Main pest control: grubs, ground tigers and other underground pests.

Control technology. Method 1: 1500 times spraying seedbed in Miao Yingchun;

Method 2: 500 times for Mebang Jiatuo + 1000 times for Casben to spray the seedbed;

Second, the germination period.

Main diseases: viral diseases, cataplexy.

Main insect pests: aphids, whiteflies, thrips.

It is difficult to have a harvest and benefit from planting watermelons without pesticides. Generally, the medicine is taken once every 7-10 days. Even if the seedling stage is not sprayed for 1 month, the late maturity stage is not sprayed for half a month. It should also be played 5-7 times during the growth and fruiting period. Unless it is organic watermelon, no pesticides.

Microbial preparations and plant-derived pesticides are more reliable, and organic pesticides are also easy to use.

Is it insect removal, or acid leaf blight, or powdery mildew, or mite pest.

1. Planting watermelon does not need to be deliberately medicated, and if it is a disease, it needs to be properly medicated. If it is downy mildew and anthracnose, it can be sprayed with zeb, usually at intervals of 7-10 days.

2. Mancozeb is also a commonly used fungicide, which can well prevent and control leaf spot, blight, black spot disease, etc., and the interval time is about a week. When actually taking the drug, the type of drug should be selected according to the situation.

Grow watermelons. Treat the soil. Pesticides resistant to heavy cropping.

Hello dear, planting watermelons requires choosing suitable soil and fertilization methods, and at the same time, you also need to pay attention to the prevention and control of pests and diseases. Here are some notes for growing watermelons: Soil Treatment:

Watermelons prefer warm, moist, loose, fertile soil with a pH in between. Before planting, the soil should be treated, including ploughing, fertilizing, and adjusting the pH level. Fertilization method:

Watermelon requires a lot of nutrients, especially elements such as nitrogen, phosphorus, and potassium. If you are too bad to fertilize the soil, you can use a combination of organic fertilizer and chemical fertilizer to improve the fertility of the soil. Pesticides resistant to heavy cropping.

Heavy stubble refers to the accumulation of a large amount of residues of the same crop in the soil, resulting in problems such as decreased soil fertility and increased pests and diseases. In order to prevent and control heavy cropping, some pesticides resistant to heavy stubble can be used, such as the pesticide "Liangzhubao" recommended by the farmer's network, the main ingredient of the pesticide is ciprofloxacin, which can effectively inhibit pathogenic bacteria and insect pests in the soil, and improve soil fertility and yield. Pest control:

Watermelons are susceptible to a variety of pests and diseases, such as fruit flies, downy mildew, anthrax, etc. In order to control pests and diseases, Keqin cherry can use biological control, chemical control and other methods, such as the use of biological pesticides such as sulfur and chlorothalonil, or the use of chemical pesticides such as dichlorvos and cypermethrin. In general, planting watermelons needs to pay attention to issues such as soil treatment, fertilization, resistance to heavy cropping, and pest and disease control, and only by taking these factors into account can we achieve good results from a bumper harvest.

Watermelon is one of the most common fruits in summer. However, due to factors such as climate change, pests and diseases, many farmers are spraying various pesticides on watermelons to protect their yield and quality. So, what kind of pesticide does watermelon need to be sprayed with?

First of all, it is necessary to pay attention to the selection of safe and effective pesticides. Common pesticides include organophosphorus, fungicides, etc., but it is necessary to pay attention to the toxicity and residue of pesticides. For some consumers with high environmental awareness, pesticide-free watermelon has become a new choice.

It is necessary to pay attention to the scientific and rational use of pesticides. The timing, dosage and method of spraying pesticides need to be strictly controlled. We should not blindly and massively use pesticides to cause environmental pollution and endanger people's health.

In short, in order to protect the environment and people's health, we can choose pesticide-free watermelon when buying watermelon, and when using pesticides, we should pay attention to choosing appropriate agricultural fan medicine, use it scientifically and rationally, protect our environment, and make our lives healthier.
