1, the sunny slope soil with deep soil layer and loose fertility is selected for planting, which is not suitable for planting in saline-alkali land. 2. Every 1000 square meter, 5000 kilograms of farmland fertilizer can be applied as base fertilizer, and 30 kilograms of calcium phosphate can be added to the soil. 3. Spraying 75% wet cotton powder in the soil for disinfection/0/5-20 days before sowing. 4, field transplantation should be carried out as soon as possible after the frost-free period, generally in early April.

I. Planting techniques of Trichosanthes kirilowii

Trichosanthes kirilowii is a deep-rooted plant, its roots can be 1-2 meters deeper than the soil, so it should be planted in deep soil and suitable for planting in loose and fertile sunny land.

2. You can use houses, trees, ditches and other places to grow Trichosanthes. Saline-alkali land is easy to accumulate water and is not suitable for planting Trichosanthes kirilowii.

3. Before planting, apply 5000 kilograms of farmland fertilizer as base fertilizer every 1000 square meters, and add 30 kilograms of calcium phosphate to the soil.

4. 15- 20 days before sowing, spray 75% wet cotton powder in the soil for disinfection, and then level the plot. Trichosanthes kirilowii is generally planted without beds, and the plot should be around the drainage ditch.

5. The field transplanting of Trichosanthes kirilowii should be carried out as soon as possible after the frost-free period, so as to win time for high yield in one year. Planting time is usually in early April, depending on the weather.

6. Reasonable close planting can increase the yield, generally planting more than 260 plants per mu.

7. When planting, first put the seedlings on the sand, cover the seedlings with a small amount of sand, then cover them with fine soil for about 2cm, and finally cover them with weeds.

Second, the management measures of Trichosanthes kirilowii

1, Trichosanthes kirilowii planted over 4-5 mu can be put on the shelves, and the surplus can be put on the ground to let it grow naturally.

2. In the 1 year of planting, select 1-2 strong seedlings for each plant, and pull out all the others. In the second year, there is usually only one plant left.

3. When the main stem of the seedling grows to 0.3-0.5m, the seedling can be moved to the frame with bamboo poles or soft ropes in time, and the lateral buds and fruits growing in front of the main stem can be erased (i.e. under the frame).

4. When the seedlings grow to about 1 m, they will be topped in time to promote the growth of lateral branches. If the nutrients grow too vigorously, it is necessary to trim the perennial hairy stems (thin and empty branches) in time.

5. When the seedlings grow to 1 ft, ditch at a distance of 0.5- 1 ft, lightly water the manure once, add a small amount of urea mixture, and then look at the seedlings once a week in the same way.

6. During the flowering period, flowers and fruit fertilizers should be properly protected according to the growth situation, and anti-dripping elements and auxin can be sprayed.

7. Trichosanthes kirilowii is a water-resistant plant. When planting, we must first choose the planting site and do a good job of drainage before planting.

8. In the later stage of Trichosanthes kirilowii, site management should be done well, and fertilization and watering should be done in time to achieve high yield.
