First, the later management of the seedlings
Mainly grasp the three ring agricultural knowledge festivals of humidity, disease prevention and temperature control. According to the situation of most town nurseries, the general humidity in the greenhouse is too high. The method of dehumidification: one is to sprinkle some pre-prepared thousand fine mud; the other is to uncover the small clear film. Disease prevention and control: The focus is on cross-spraying fungi, to prevent and cure rickets, and other disease control refers to the total 107 technical requirements. Temperature control, in the later stage should pay attention to control at around 20 °C as well.
Second, the preparation work before the transplanting of Daejeon
1. Till the land, apply enough base fertilizer, and do a good job. Generally, 20-30 ton of organic fertilizer is applied to each standard, 50 kg of compound organic fertilizer, 50 kg of phosphate fertilizer, and 3 kg of bio-clamp 1 are fully ploughed and mixed, and the hoe is prepared according to the cultivation requirements.
2.è¶ No wind or small wind weather, cover the greenhouse film, and prepare a small ring shed ring and covered nylon, covered with mulch on the hoe (preferably black mulch). Under normal circumstances, the door to the north of the greenhouse should be sealed to ensure the temperature.
3. The shed is surrounded by three ditch.
Third, the seedlings are planted
When the seedlings are in the heart of 2-3 leaves, they can be colonized (the general age is controlled at 30-40 days). On the hoe, 30-35 cm of the plant is punctured and punctured, and two stalks are generally planted in the greenhouse. After planting, the root water was poured with 3% urea solution, and the planting mouth was sealed. On the planting ridge, a small layer of small arches of 30-40 cm high and 50-120 cm is used for heat preservation, which is good for living trees.
Fourth, management requirements
1. Make sure the temperature. The temperature after transplanting should be guaranteed at around 30-35 °C. In the method, the temperature is maintained by the greenhouse film, the small ring shed cover film, and the mulch film. When the temperature is extremely low, the straw shed or the non-woven fabric is covered with frost and temperature.
2. Make sure you are at room temperature. After living the tree, pay attention to the temperature at noon from the noon temperature of 35 ° C, the method can uncover the ring film. If the temperature does not drop, you can consider re-opening the south gate of the greenhouse.
3. Timely topdressing. When the vine grows to 50 cm (usually after the end of March), it is ditched on both sides of the melon root 50 cm (see self-root), and the compound fertilizer or cake fertilizer is applied. It is best to use special fertilizer such as glutinous rice, and cover the soil. Leveling.
4. Grasp the whole branch. Prevent the grow up. Generally, 2-3 vines per plant (depending on the density of transplanting), this is the key to the success of spring cantaloupe planting, and the remaining side branches must be determined to cut off all. Sprinkle the small arch shed before and after the summer (the vine has reached the side).
5. Artificial pollination. At 6-10 am on a sunny day, pick and grow the male flowers with good pollen, remove the petals, gently spread evenly on the male flower head, and make a mark.
6. Choose melon and melon. Choose about 14 leaves of melon, each plant only one melon, in order to facilitate early maturity and strong.
7. Apply fertilizer to the fruit. One week after the first batch of melons, the fruit fertilizer can be applied, and urea can be used. Then, spray 0.5% dihydrogen phosphate solution every 7 days, keep the soil moist, and control the water one week before harvest to improve the quality.
8. Pest control. It is necessary to regularly control spermatozoa and the viral diseases caused by it.
