Melon farmers need to know the open field watermelon high-yield planting techniques!

Watermelon is a cool summer Jiapin, but also in all parts of the country have cultivated fruit. Every year to early spring in February and March melon farmers began to sow, the following to understand the high-yield watermelon planting technology under the open field!

1. Basic information of watermelon

1. Watermelon is the most well-known name, but it is well known that it has summer melon, cold melon, green door green jade room and other names. Although watermelon is widely cultivated in China, there are many varieties, but the original species is from Africa, in China Jin, Yuan Dynasty only introduced.

2. Watermelon is an annual vine with stout stems and branches. The stems and branches are covered with white or tan long and dense pilose hairs. Watermelon leaves are triangular ovate with white-green paper. The edges of the leaves are undulated or sparsely toothed. The apex of the leaves is obtuse and the base is heart-shaped. Watermelon is monoecious. The pale yellow flowers are also pilose. The next frame will bear fruit every year.

3. Watermelon tastes sweet and juicy, refreshing and thirst-quenching, has the title of "King of Summer", rich in a large number of vitamins, glucose, protein, fruit acid and other nutrients, swelling diuretic, moisturizing sunscreen whitening, stimulating gastrointestinal motility, helping defecation and so on, very suitable for pregnant women, sedentary office crowd consumption, but it should be noted that each time the amount of consumption is not too much, avoid diarrhea and other adverse reactions.

2. What are the high-yield planting techniques of open-field watermelon?

Watermelon planting can be carried out by soaking seeds to germinate seeds. First, the selected watermelon seeds with full particles, high yield, good quality and strong disease resistance are dried for two days for disinfection, and then soaked in warm water of about 55 degrees Celsius. After treatment, the watermelon seeds can be sown and planted when they grow embryos half a centimeter long.

1. Watermelon is a kind of fruit that likes warm and dry climate, so it is best to choose a place with deep soil layer and rich organic matter; before planting, the soil should be deeply turned and dried, and at the same time, the decomposed farm manure, compound fertilizer and other fertilizers should be mixed with the soil that needs backfilling.

2. Open field watermelon is covered with plastic film. The sowing date is appropriate in late April. The sowing method is to sow seeds in the middle of plastic film, about 2-3 seeds per hole, the sowing depth is 2 cm. After planting, it is covered with fine soil and pressed tightly. Generally, the seed amount per mu is about 200 grams.

3. After the watermelon seedlings are sown, the seedlings should be opened for ventilation. After the watermelon has three or four leaves, it can be planted. The planting density per mu is best maintained between 600 and 800 plants. The density is determined according to the size.

4. The planting temperature of open field watermelon is not easy to control, we must pay attention to the watering problem during planting, but the water required for watering in each period of watermelon is different, so the following is to tell the watering problem of watermelon in different periods.

(1) Watermelon watering in seedling stage should be controlled well. Do not water after wetting the seedbed until germination. Water less in later stage. For direct seeding and planting watermelon seedlings, ditch watering should be conducted to allow water to seep down.

(2) Watermelon vine growth should be appropriate to increase the amount of watering, generally according to the moisture of the soil, wet do not water, soil dry to water, watering time is best to choose in the morning.

(3) During the flowering and fruiting period of watermelon, it is necessary to water the goose empty or even well, neither dry nor too wet; in addition, when watermelon begins to expand, it is necessary to increase the amount of watering appropriately, generally watering once every four or five days; dry weather and watermelon of two or three catties are the peak period of water demand, which is about watering once every two or three days, and stop watering before watermelon is ready to mature and appear on the market.

5. Reasonable topdressing is the premise of high yield and high quality of watermelon, so attention should be paid to topdressing during watermelon growth period. Generally, topdressing should be determined according to actual conditions; seedling fertilizer or compound fertilizer should be applied after planting, vine fertilizer should be applied after true leaves grow, and melon fertilizer and fruit fertilizer (mainly decomposed human and animal manure or compound fertilizer) should be added when young fruits are stable (egg size).

6. Finally, attention should be paid to the damage of blight, anthracnose, aphid, Liriomyza sativae and other pests to branches and leaves and young melons during watermelon growth. The application of melon farmers must be discovered in time during planting management and chemical or physical control; the infected plants should also be removed in time.

The above is for everyone to introduce the watermelon open field planting technology, in addition to remind everyone in the harvest is best to choose in the morning, and according to the actual maturity of the situation to take batches listed.
