7 key points of pollution-free towel gourd cultivation in summer towel gourd market

Towel gourd

Soil requirements. In planting towel gourd, the fields with deep plough layer, flat topography, convenient drainage and irrigation and good physical and chemical properties were selected for planting towel gourd which had not planted cotton in 3 years and non-melon crops in the previous crop.

Variety selection. Non-transgenic towel gourd varieties with high quality, high yield, disease and insect resistance, strong stress resistance, strong adaptability and good marketability were selected.

Seed treatment. Soak the seeds in about 50 ℃ of warm water for 20 minutes, or soak the towel gourd seeds in 100 times glacial acetic acid for 30 minutes, rinse the seeds with clean water, dry the seeds for 2-4 hours, soak the seeds with 10% trisodium phosphate for 10 minutes, or mix the towel gourd seeds with 50% thiram wettable powder of 3% seed weight.

Nutritious soil for raising seedlings. It can be mixed with high-quality mature organic fertilizer from the fields that have not planted melon crops in 3 years. Among them, high-quality mature organic fertilizer accounts for 30%, which is used after screening. Every square meter of seedling bed is mixed with 50% carbendazim or 5-10 grams of 50% methyl thiophanate wettable powder to disinfect the seedling soil. Mix 50% carbendazim wettable powder with 50% thiram wettable powder at 1:1, or 25% nail cream wettable powder with 70% Dysen zinc wettable powder at 9:1, mix 8-10 grams per square meter with fine soil 15-30 kg, disinfect the nursery bed.

After the towel gourd seedlings are more than 1 meter high, 800kg 1:1 rotten dung water can be applied combined with watering. 1200 kg of rotten manure water can be applied in the full fruit period.

Field management.
