Experience in Growing Seedless Watermelon

Seedbed establishment seedbed must be selected in leeward, sunny, high terrain, close to the water source, in order to manage. Seedbed width 2.5 meters, 0.15 meters deep, length according to needs. In the establishment of seedbeds should pay attention to make the bottom as flat as possible, before the system bowl at the bottom of the seedbed sprinkle a layer of sand, so that seedlings.

The preparation of nutrient soil is mixed with 0.5 cubic meters of organic fertilizer and 3~6 kilograms of plant ash per cubic meter of soil, and it is best to add appropriate amount of carbendazim. After the nutrient soil is prepared, the seedlings are raised in the nutrient bowl.

Seed treatment Take warm water at 55℃~60℃, put the seeds in and stir for about 15 minutes. After blanching, take out the seeds, soak them in cold water for 4~6 hours, then wash them clean and rub off the moisture and mucus on the surface of the seeds to improve the germination rate.

Germination gently crack open seeds before germination, crack is appropriate, before the crack to gargle (pollination varieties do not need to crack seed). The seeds are placed at 28℃~35℃ after cracking, and most of the seeds can sprout after 24 hours. When the buds grow to about 0.5 cm, they can be sown. When germination as far as possible to maintain constant temperature, such as close warm bud is better.

Sowing time is generally from late March to early April. The method is: lay the seeds flat, one in each bowl, and cover them with 1.5 cm thick fine soil after sowing. In addition, but also available wheat bran mixed with a small amount of trichlorfon scattered in the seedbed, in order to trap pests.

Seedbed management after covering soil in time to build a shed, cover the film, and then use wet soil compaction film edge to improve ground temperature, accelerate emergence. After emergence, if the temperature is high in sunny days, attention should be paid to ventilation. The ventilation time should be selected between 10 a.m. and 3~4 p.m. on sunny days. In rainy days or when the temperature is low, less ventilation or no ventilation can be provided. Seedless watermelon seedling age is generally about 30 days, during this period should be strictly controlled seedbed humidity, as long as the bottom water is sufficient, can not be watered, such as water shortage, should be a thorough irrigation is appropriate. In the afternoon of the day before transplanting, water should be poured once for transplanting and planting.
