Last Updated: 2024/11/08, Towel gourd is heat-resistant and not cold-tolerant, the optimum temperature for seed germination is 25-35 ℃, and the optimum temperature for seedling growth is 25-30 ℃ higher than that of other melons. Towel gourd cultivated precociously is usually raised by electric heating, and the seedling age is 30-40 days. It can be planted when it has 4-5 true leaves.

Towel gourd is heat-resistant and not cold-resistant, the suitable temperature for seed germination is 25-35 ℃, and the suitable temperature for seedling growth is 25-30 ℃, which requires higher temperature. Towel gourd cultivated precociously is generally raised with electric heating beds. The seedling age is 30-40 days, and it can be planted with 4-5 true leaves. According to the planting period, the suitable sowing time can be calculated. Let's take a look at the seedling technology of towel gourd.

Variety selection of towel gourd

Towel gourd should choose varieties with high quality, high yield, good commercial properties and suitable for the market. Long stick-shaped varieties should be selected for cultivation in winter and spring, and the market should be oriented to varieties from Hong Kong, Macao and South China, such as green, Shuangqing, green and so on. Summer and autumn cultivation should choose short stick-shaped varieties facing the island market, such as Thailand towel gourd.

Seed treatment of towel gourd

1. Disinfection and seed soaking treatment

Soak the seeds in ① at room temperature: wash the seeds in water at room temperature, then soak the seeds in water for 3-5 hours.

Soak the seeds in ② warm soup: soak the seeds in warm water of 50 ℃-55 ℃, keep the water temperature evenly for 15-20 minutes, wash the seeds at room temperature, and then soak them in normal water for 3-5 hours, mainly to kill the germs on the seed coat surface.

Soak the seeds with ③ medicine: soak the seeds in clear water for 1-2 hours, soak them in 1500 times aqueous solution for 10 minutes, remove and rinse, and then soak the seeds in normal temperature water for 2-3 hours to control towel gourd Botrytis cinerea.

2. Seed germination method: germinate or not, depending on the temperature. The sterilized and soaked seeds were removed and washed and placed under 25 ℃-30 ℃ under variable temperature or constant temperature, moisturizing and accelerating germination.

Sowing method of towel gourd

1. Sowing time: the suitable sowing time should be selected according to the cultivation season, air temperature conditions and market demand, and the sowing practice should be carried out on a sunny day, covered with plastic film, and the hole should be as small as possible so as not to lift the film when the wind is strong.

2. Sowing rate: according to the planting density of towel gourd, generally plant 8-1200 plants per mu in the field, sow 2 seeds per hole, and use about 350,500g.

3. Sowing method: the survival rate of towel gourd transplanting is low, and the direct seeding method is generally adopted. From March to April, the soil is prepared to make a bed, about 3 meters wide, and the seeds are soaked to promote germination and sow two rows on both sides of the border. Plant spacing 35 cm, hole opening, 3 seeds per hole, about 300-450 grams of seeds per hectare, single-row planting, plant spacing of 30-50 cm, 2 seeds per hole, depth of 1-2 cm, seeds flat, soil field capacity 75%, if too dry, cover hay to keep warm and wet.

4. Post-broadcast management

① inter-seedling fixed seedling: direct seeding towel gourd in the open field. Generally, when there are 3-4 true leaves in the seedling stage, one strong seedling is left in each hole, and water and fertilizer is irrigated 2-3 times, cultivated with plastic film, water and fertilizer is poured 1-2 times after the seedling is fixed, and then the hole is compacted with dry fine soil.

② fertilizer and water management: the first heavy fertilizer was applied by drawing vine combined with soil cultivation, 1000 kg of rotten farm manure, 20 kg of cake fertilizer and 20 kg of ternary compound fertilizer per mu were mixed and applied into the cultivation ditch, and the second heavy fertilizer was applied at the peak stage, 20 kg of ternary compound fertilizer and 10 kg of potassium chloride per mu, and 10 kg of ternary compound fertilizer or 20 kg of cake fertilizer per mu.
