Leave a few vines in cantaloupe planting

Hami melon is a transformation of melon, the fruit is round or oval, produced in Xinjiang, not only delicious, but also rich in nutrition, high medicinal value, and has a high planting prospect. So, how many vines are left in cantaloupe planting?

1. Leave a few vines in cantaloupe planting

Cantaloupe planting generally leaves two vines, one main vine and one side vine, which is helpful to increase the yield. Hami melon is widely cultivated in China, and diseases such as bacterial leaf spot, vine blight and fungal leaf blight often occur in the production process.

1. Bacterial leaf spot

[symptoms] in the early stage, watery spots appeared near the veins of the dorsal leaves, which expanded rapidly and became one piece, with yellow halos on the edges.

[control methods] at the initial stage of the disease, 77% Dorin 500 times or 3% Zhongshengmycin 800 times were foliar sprayed 2-3 times, once every 4-5 days.

2. Vine blight

[symptoms] damage melon vine, leaf, melon vine disease part often split, surface dense small black spots, serious disease part spill amber glue. The disease was more serious when the average temperature was 18-25 ℃, high soil moisture, continuous cropping, poor drainage and weak growth of watermelon.

[agricultural measures] ① strictly controls soil moisture to avoid excessive water content. ② can reduce the wound of melon and vegetable and reduce the infection rate of pathogen. Avoid irrigation in the field during the onset of ③.

[drug control] at the initial stage of the disease, the use of 1800 times of 25% Kailun EC or 32.5 times of Amimicol suspension 1500 times 24% should be 2000 times foliar spraying. The frequency of application depends on the occurrence of the disease, generally 2-3 times, once every 3-4 days.

3. Powdery mildew of Hami melon

[symptoms] the pathogen mainly harms leaves, and stem vines and petioles can also be damaged. In the early stage of the disease, small round spots appeared on the leaves, and the disease spots were enlarged and connected into pieces. in severe cases, the positive and negative sides of the leaves, stems and petioles were covered with white powder, and the diseased leaves were yellow, brittle and curled. The pathogen overwintered in the soil with the plant disease residue as a closed capsule. Spread by airflow and Rain Water. The disease is serious when the humidity of the melon field is high, the plant growth is dense and the ventilation is poor.

[control methods] ① should strengthen field management, increase the application of phosphorus and potassium fertilizer, prevent plant overgrowth and early senescence, scientific pruning, ventilation and light, and reduce humidity. In the early stage of ②, 200mu sulfur powder 2kg / mu can be used, spray when there is dew on melon seedlings in the morning and evening, or 200kg / mu of sulfur suspension, 67g of 15% chlorothalonil wettable powder, or 200g / mu of 75% chlorothalonil wettable powder, or 1000 times of methyl thiophanate wettable powder, once every 7 times 10 days for 3 times in a row.
