Planting method of Ham Melon in South America

Stubble soil preparation: choose to plant in plain or low-lying land with sufficient light and fertile soil. Planting requirements: the seeds should be planted in a nutrition bowl and transplanted when the outdoor temperature is stable above 20 ℃. When transplanting, the distance between plants is 1.3-1.6 m, and 5-7.5 kg farm manure and 200 g chemical fertilizer are applied to each hole as base fertilizer. During artificial transplanting, the seedlings should be put into the hole and the soil should be soaked thoroughly. Field management: weeding should be carried out during the growth period, and timely prevention and control of diseases and insect pests.

First, selecting stubble for soil preparation

1. Choose to plant in Pingchuan with good drainage, sufficient light and fertile soil, or in low-lying land and hilly land with irrigation conditions, but not in watermelon and other melon plots.

2. According to the plant spacing of 2m, the row spacing of 2.5m is the standard for soil preparation, 120,140seedlings can be planted per mu, and 5-8kg oxidized farm manure can be applied at the bottom of each seedling.

3. In the later stage, topdressing can be carried out according to the growth of South American ham melon.

II. Planting requirements

Pick out the seeds that have sprouted every day, plant them in a nutrition bowl, and transplant them when the outdoor temperature is more than 20 ℃.

3. Seeding in seedbed

8-cm horse dung or crushed grass under the seedling bed, cover it with a layer of soil, gently tread flat, disinfect with 70% dioxone wettable powder, and cover the plastic film at the same time.

IV. Seedbed management

1, during the period to properly watering, but should not appear stagnant water, and control rodents, pests, generally can be used phoxim, trichlorfon mixed wheat bran (poison bait) control, at the same time timely weeding, and spraying foliar fertilizer.

2. The proper temperature of seedling bed is 25-28 ℃, no less than 15 ℃ at night, generally 35-40 days of seedling age, and 5-7 days before transplanting.

5. Timely transplantation

1. Dig big hole: dig the big hole of 20cm × 20cm before transplanting, according to the plant distance is 1.3m-1.6m, protect seedling about 120140m / mu, each hole can apply 5-7.5kg farm manure, and 100g-250g chemical fertilizer (diammonium, potassium fertilizer, magnesium powder ratio is 3 ∶ 1 ∶ 1) as base fertilizer.

2. Artificial transplanting: the nutrition bowl should be watered sufficiently before planting, and then the seedlings should be put into holes, covered with soil and then watered with sufficient water. At the same time, film mulching, hole-digging and seedling placement should be carried out, or double-film transplantation should be selected, that is, arch film should be covered after transplanting.

VI. Field management

1. In the process of growth, weeding should be carried out manually, and diseases and insect pests should be controlled in time. It can be combined with topdressing and spreading straw, using rice straw or wheat straw 1kg per square meter.

2. To avoid grass shortage, when the main vine grows to 50cm or so, you can combine irrigation with urea 100g-250g per plant. Topdressing should not be too close to the main root, avoid root burning, and do not spread urea on the leaf surface to avoid leaf burning.

3. Each plant can retain 2 main vines, 2 main vines are placed laterally on the open ridge, and directional soil can be cultivated for 1 time.

4. When the first-order bifurcation grows to 3 leaves, it can be pinched and pinched. Generally, 4-6 melons can be retained per plant, each weighing about 2-6Kg.
