How to plant watermelon with high yield

In order to achieve high yield, watermelon must first select excellent varieties, base fertilizer should be fully applied, and seeds should be dried and soaked to improve their physiological activity. Due to the large amount of fertilizer needed during the growing period of watermelon, regular fertilization must be applied, and farm manure can be sprinkled around the plant. Pay attention to the arrangement of vines, remove weeds, watermelon florescence to remove inferior flowers in time, if sunny flowering insects can carry out pollination, if rainy days need artificial pollination, which is conducive to increase yield.

1. Soil preparation and fertilization

The main results are as follows: 1. First, the soil can be turned deep and dried for about 15 days, and about 50-75 kg of quicklime can be applied per mu, then raked to make a border, with a ditch of about 2.5m, a height of about 40cm on one side and an inclined border of about 20cm on the other side.

2. On the side near the high border, the planting ditch can be dug, the width is about 40cm, and the depth is about 25cm, and then the ditch is dominated by rotten farm manure, about 1000-1500 kg per mu, with borax about 1000-2 kg, ternary compound fertilizer about 25 kg, magnesium sulfate about 4 kg, and then let the fertilizer and backfill soil mix evenly.

Second, soaking seeds to accelerate germination

The main results are as follows: 1. Excellent varieties should be selected before planting. In order to prolong the supply period of watermelon and improve economic benefits, early, middle and late ripening watermelon varieties should be selected to sow at a suitable time.

2. In order to improve the physiological activity of the seeds, the seeds should be dried for about 1-2 days before sowing, then soak the dried seeds in warm water of 55 ℃ for about 5-6 hours, then fish out, wash the seed coat with 5% lime water, rub the seeds with hands until the seeds are not slippery, and finally wash the seeds, air-dry moisture can be placed in the greenhouse to accelerate germination.

Third, sowing seeds

When the sprouts grow to 1-2cm, you can sow about 2-3 seeds in each hole. When sowing, the tip of the tooth is facing down, then cover a thin layer of soil, and then pour the root water after sowing. If it is a sunny day, it should be watered again after 2-3 days. When the seedlings grow out of 2-3 true leaves, the seedlings can be fixed, the missing seedlings can be made up in time, and the two plants can leave a sturdy one.

IV. Rational fertilization

During the growing period of watermelon, the amount of fertilizer is relatively large, so farm manure should be sprinkled around the plant. Watermelon absorbs farm manure more quickly, which is conducive to the rapid growth of plants, so it is necessary to apply fertilizer regularly.

Fifth, arrange the vines

1. When the watermelon seedlings grow to 0.5m long, the watermelon seedlings can be moved to the opposite direction and the top of the seedlings can be removed. Other seedlings can also be grown to a certain length according to this method. In addition, in order to avoid nutrient loss, weeds should be removed in time.

2. In the flowering stage of watermelon, the excess inferior flowers should be removed in time to prevent nutrition from being consumed, which is beneficial to increase the yield.

VI. Pollination

If the watermelon blossoms on a sunny day, the insects can pollinate, and the success rate of pollination is relatively high, so there is no need for manual pollination. In case of frequent rainy weather, fewer insects come out, so artificial pollination is needed. First of all, shake the powder on the male flowers on the female stamens. If the flowers wither, they will not bear fruit.

7. Prevent cracking melons

Generally speaking, watermelons are easy to crack when they are about to ripen. In order to isolate the ground on the surface of watermelons, you can spread a layer of wheat stalks under the watermelons to prevent the sun from cracking, and you can also cover a layer of wheat stalks on top of watermelons. After laying, try not to touch the watermelon to prevent cracking.
