Planting time and method of roasted melon

Planting time: it is suitable to be planted in late April. Planting method: choose to plant in corn, wheat, potato and other plots, and apply appropriate amount of urea, American diammonium, phosphate fertilizer and farm manure as base fertilizer per mu; after sowing, when the seedlings grow to 5-6 leaves, about 2000 plants can be transplanted per mu; after 3-4 times of harvest, appropriate amount of diammonium phosphate can be applied; in the later stage, coring and artificial pollination should be carried out in time; tender fruits can be picked 5-7 days after flowering.

First, planting time

The planting time of roasted melon is late April, and plastic film should be covered as early as possible before sowing, which is helpful to improve soil temperature and humidity.

II. Soil preparation and fertilization

1. Ridging 5-7 cm, 50-60 cm wide and 30-40 cm wide in the completed plot, covering 70 cm wide plastic film when soil moisture is good or heavy rain grabs moisture.

2. Before sowing, corn, wheat, potato and other plots are selected for soil preparation and fertilization. 10-15 kg urea, 20-30 kg American diammonium, 50-70 kg phosphate fertilizer and 5000 kg fully mature farm manure can be applied as base fertilizer per mu.

Third, sowing and transplanting

The main results are as follows: 1. Direct seeding can be adopted to plant double seedlings in each hole. When the seedlings grow to 5-6 leaves, the growth rate of roasted melons is relatively fast, and sparse planting should be appropriate during the period, which is conducive to ventilation and light transmission.

2. When transplanting, try not to damage the rhizome and leaves, which is beneficial to the photosynthesis and flower bud differentiation of the transplanted seedlings. Generally, the suitable distance between plants is 50-55 cm, and about 2000 plants can be transplanted per mu.

IV. Temperature management

Using plastic film to cover roasted melon can increase soil temperature and humidity and create good conditions for seedling growth.

V. Water and fertilizer management

During the period from sowing to the first melon harvest, water should be strictly controlled, watering should not be avoided, and seedling running should be avoided. After 3-4 harvesting, foliar spraying can be carried out with plant power 2003 of 1, 000 times liquid, once every 20 days, 2-3 times continuously, and 10-15 kg of diammonium phosphate per mu can be exchanged for water.

6. Pick the heart in time

The main results are as follows: 1. When the cotyledons of roasted melons unfold and the first true leaf appears, 2-3 seedlings can be retained, 4-leaf seedlings can be fixed, 1 strong seedling can be selected, and 5-6-leaf seedlings can be coring.

2. After the occurrence of lateral vines, 2-4 strong lateral vines were selected, and 2-3 strong accessory vines were left after reaching 4-5 leaves, and 2-3 leaves were left at the first end of the fruit to pick the heart, and in the later stage, the stilts on the vine tip were picked, generally, the fewer plants were planted, and the more plants were left, the fewer vines were left.

7. Artificial pollination

Artificial pollination is beneficial to increase the setting rate. When the male flowers are few or the pollen quantity is insufficient, you can smear it on the base of the female style and on the young melons at the base of the Corolla, or at 8-10:00 in the morning, remove the male flowers at that time, remove the Corolla and expose the anther, and then gently apply a few on the pistil head.

VIII. Timely harvest

1. Roasted melons grow very fast. Generally, 5-7 days after flowering, the weight of roasted melons can reach 0.25 kg. At this time, tender fruits can be picked in time, and it is easy to compete for nutrients among the fruits, so timely harvesting can promote the healthy growth of plants and prevent premature senescence. It is also beneficial to improve yield and quality.

2. Generally, plastic film mulching is used to cultivate roasted melon, which is an important measure to improve the yield and quality of burned melon and increase the income of farmers.
