Planting time
Planted in early spring, planted in late February, seedlings were planted in 35-40 days, heated by means of warming, planted in the greenhouse in mid-April, and listed in early June.
Spring bare planting from late March to late May sowing, seedling age about 30 days. Protect the seedlings in the protected area and plant them in bare land or cover a small shed after the frost period.
Sowing seedlings
Nutrient soil preparation Nutrient soil preparation method is more commonly used 2 / 3 peat soil plus 1/3 not melon field soil mixed sifted, or 1/3 decomposed farmyard fertilizer plus 2 / 3 Dae field soil. Add 2 kilograms of superphosphate per square soil, sterilize with 800 times of carbendazim solution, or fumigation with formaldehyde.
Immersion germination can be soaked with 55C warm water, disinfection, stirring constantly to about 30C water temperature. After immersing for 4 hours, the seeds were washed, then tightly wrapped in a wet towel, and germinated under the environment of about 30C.
One day before sowing and sowing, 800 times methylthiobutem liquid was used to irrigate the seedlings. When the seed buds grew to a height of about 0.5 cm, the seedlings were sown in the seedling tray. When sowing, the seeds should be laid flat, with the bud tip down, cover with 1.5 centimeters thick fine nutrient soil, and use 800 times thiophanate-methyl liquid to soak the seedling plate, keeping the temperature at 25-30C to ensure that the seedlings are neat and tidy. After emergence, the temperature can be maintained at 18-28C. Seedlings rather dry not wet. Early spring should prevent freezing injury and ensure sufficient light.
Field management
Colonization is generally planted by multi-vines and multi-fruit vines. Plant spacing is 60-80 centimeters and 180-200 centimeters, and 530-730 plants can be planted per acre. It can also be planted in vertical racks with a spacing of 50 cm (100-140 cm) and colonization in two rows.
Fertilizer is mainly based fertilizer, supplemented by top dressing. Base fertilizer is applied or spread with 60 kg compound fertilizer and 3,000 kg of pig bar fertilizer per acre. After the whole growth period, it is necessary to apply extension vinegar and swollen melon fertilizer.
The fruit is small because of the small size. To achieve higher yields, it should be planted in multiple vines and fruits. Usually, one main vine and three to four vine seeds are kept. When the fruit is left, the first female flower on the main vine is removed and the rest are Two pods of melons can be kept and the following vines should be removed as soon as possible.
Diseases and Insect Pest Control Small watermelon varieties have strong disease resistance. The general diseases are blight, wilt disease, virus disease and anthrax. Pest control is best done 7-10 days.
