How seedless watermelons are cultivated
Today, the editor will introduce the topic of how seedless watermelons are cultivated and the key points of seedless watermelon cultivation techniques related to flower cultivation. Next, the editor will provide an introduction for netizens.
Seedless watermelons, due to the absence of seeds, have good quality, are convenient to eat, have high yield and disease resistance, and are suitable for storage and transportation. They are widely welcomed by producers, operators, and consumers. The planting area is gradually expanding, and a few farmers in various regions are planting them.
1 Preparation of the melon field: Although seedless watermelons are not strict about soil requirements, it is still necessary to create a suitable environment for high yield and good quality. Due to their characteristics of fearing continuous cropping, waterlogging, drought, and having a developed root system, when selecting a melon field, it should be chosen on high and dry land with abundant sunlight, deep soil layers, good permeability, and convenient irrigation and drainage to ensure the normal growth and development of seedless watermelons. After the early spring thaw, rake the melon field finely and level it, dig melon trenches at the predetermined row spacing, with a depth and width of 30cm each. Irrigate enough water to moisten the bottom of the trench, apply 4000-5000 kilograms of high-quality, decomposed farm manure per mu, 50 kilograms of ternary compound fertilizer (nitrogen, phosphorus, potassium), or 50-60 kilograms of special watermelon fertilizer, and spray phoxim for disinfection, then cover the ridge with plastic film. This work should be done 5-7 days before planting.
2 Seedling raising and transplanting with nutrient pots: As seedless watermelons are triploid, the seed quality is poor. The measures include: soaking seeds in 55°C water and stirring continuously, then cooling to 30°C and soaking for 8 hours to help the seeds absorb water and soften the seed coat; shell-breaking to reduce the resistance of the radicle breaking through the shell; increasing germination temperature; using保温 nutrient pots for seedling raising.
3 Reasonable cultivation of pollination varieties: When the seedlings have grown to three leaves and one heart, they can be transplanted. Plant 500-550 seedless watermelon seedlings and 50-100 pollination variety seedlings per mu. The pollination variety can be chosen as Lüqing No. 5 or Lüqing No. 7 (varieties with more pollen and early maturity) as the pollination variety. The row spacing is 1.8-2.2m, and the plant spacing is 0.6-0.5m.
4 Field management should pay attention to pruning: Pruning adopts the method of one main and two auxiliary vines, i.e., one main vine for fruiting and two auxiliary vines for nutrition. Prune the vines when they are 30-50cm long to prevent them from being uprooted by the wind and affecting growth. Maintain three vines throughout the growth period and top the main vine at 10 leaves after the fruit is set.
5 Three points to note for artificial pollination: To ensure that female flowers at the right position bear fruit, artificial pollination must be carried out. The points to note include: timing, skillful operation, and covering with paper bags in the rain.
6 Pay attention to the long-term prevention of pests and diseases: Preventing and controlling pests and diseases is a regular task in field management and an important part of ensuring a good harvest. Apply a special formula of fungicide + insecticide + foliar fertilizer + activator every 7-10 days.
7 Strengthen fertilization and water management: Water the seedless watermelons at least 2-3 times during the entire growing period. Apply top dressing with quick-acting fertilizers and manage water and fertilizers according to local soil and climate conditions.
8 Harvest at the right time: Seedless watermelons take about 35-40 days from flowering to maturity.
That's all for the introduction of how seedless watermelons are cultivated and their cultivation techniques. Hope this information is helpful for everyone to learn and understand!
