In what month can the vegetables harvested in the winter in the greenhouse be able to raise seedling

Seedlings can generally be raised in October. Select some vegetable seeds of good quality, evenly sprinkle them in fertile nutrient soil, the gap between seeds can not be too high, and you can grow seedlings after a period of time with appropriate organic fertilizer.

First of all, it is important to understand that greenhouses usually refer to greenhouses without back walls, and those with back walls are called greenhouses.

Generally, fruits and vegetables must be grown in greenhouses. For example, cucumber growth at 13-33 ° below 13 ° is inhibited by grafting and several special varieties can grow at 8 °.

The temperature of tomatoes is more complicated, and the fruiting period is different from the vegetative growth period, and the temperature is usually about 5° lower than that of cucumbers.

Fruits and vegetables below minus 2°C may be frostbitten.

Leafy vegetables are relatively frost-resistant, rape is resistant to -7° low temperature, and celery is resistant to -5° low temperature. Artemisia chrysanthemum and appetus are also relatively resistant to low temperatures.

Choose the time to plant vegetables according to the season, vegetables suitable for planting in spring greenhouses: spinach, baby greens, amaranth, lettuce, eggplant, cucumber, water spinach, leeks, sweet potato vines, chrysanthemums, peppers, tomatoes, loofahs, winter melons, pumpkins, cowpeas, bitter gourds, watermelons, lentils, fungus Vegetables sown in summer: water spinach, watercress, cauliflower, oily lettuce, cucumber, winter melon, pumpkin, watermelon, vegetable melon, bitter gourd pepper Autumn planted vegetables:

Spinach, cauliflower, garlic, coriander, cabbage, kraft, green onion, lettuce, lettuce, celery, pea sprouts. Vegetables grown in winter: greens, choy sum, spinach, lettuce, coriander, lilies, mustard greens.

It can be planted all year round, baby cabbage, green onions, garlic. Sowing seeds by month, the south can be appropriately advanced, the north can be delayed for half a month or a month, the specific time can be determined according to the local temperature. 1.

1. Cauliflower, cabbage, amaranth, lettuce and other crops planted in the open field in autumn are selected to raise seedlings from the end of July to the beginning of August.

2. Peppers, bell peppers and colored bell peppers planted in autumn sunlight greenhouses are raised in late July, and the greenhouses with poor thermal insulation performance should be bred 5 10 days early, and the colored bell peppers should be properly bred early, and the sowing period is in mid-July.

3. Autumn and winter stubble greenhouse tomatoes are generally raised in mid to late July, planted in mid to late August, and harvested from mid-November to mid-January.

Second, with sports seedlings to take tomatoes as an example:

Tools: tomato seeds, seedling substrate, seedling tray, watering can.

Steps: 1. Prepare the items needed for seedling raising.

2. Pour an appropriate amount of base fertilizer on the ground, put water on it, pinch it until it is restless, and the humidity reaches about 60%.

3. Next, put it on a plate, gently flatten, don't pack too much, and the plate can be as flat as the plate.

4. Take a few seedling trays and press them, and some pits will appear after pressing.

5. Put the seeds in the pit of the seedling tray**, usually we can put 1-2 seeds.

6. After the seeds are finished, pour in the base fertilizer and flatten it, water it again, put the seedling tray in a ventilated place, and transplant it after germination, so that the tomato seeds will be cultivated.

a. Cauliflower, cabbage, amaranth, lettuce and other crops planted in the open field in autumn.

Seedlings are raised at the end of July to the beginning of August. Open-field cucumbers, selected from heat-tolerant, early-maturing, disease-resistant varieties, sown in early to mid-July, and in the late August to early October ** autumn off-season market. It is necessary to apply enough organic fertilizer, make a tile ridge and high furrow, not spread mulch, and plant it at a density of 70 75 cm 30 33 cm.

b. Peppers, bell peppers, and colored bell peppers grown in autumn solar greenhouses.

Seedlings should be raised in late July, and the greenhouse with poor thermal insulation performance should be incubated 5 to 10 days early, and the colored bell pepper should be properly bred early, and the sowing period should be in mid-July; Generally, the seedling age is 45 to 50 days, and it is planted from late August to early September, and harvested and marketed from early November to the Spring Festival. In the greenhouse with good ventilation and low temperature, the 50-hole plastic hole tray is used, and the special substrate for seedling raising or peat, vermiculite and perlite is used as the substrate. Do a good job of soaking seeds in warm soup and soaking seeds to promote germination, germinate in 25 30 environment for 6 7 days, and sow seeds when they germinate.

c. Autumn and winter stubble greenhouse tomatoes.

Generally, seedlings are raised in mid to late July, planted in mid to late August, and harvested from mid-November to mid-January; Greenhouses with poor thermal insulation performance should raise seedlings appropriately. In recent years, tomato yellowing leaf curl virus disease has occurred seriously, and once the disease is infected, it often causes a significant reduction in yield or even no harvest. The best prevention method is to start from the seedling stage, and use "full protection" measures such as shade nets, greenhouse film to prevent rain, insect nets and insects to cultivate strong seedlings and strictly prevent the spread of whitefly.

d. Autumn greenhouse cucumber.

planting in late July; Cucumbers are selected from early-maturing, disease-resistant, high-quality varieties such as "Zhongnong 16", seedlings are raised in mid-July, planted in early August, and 72-hole plastic hole trays are used to raise seedlings, with peat, vermiculite and perlite as the substrate; Cucumbers can also be sown directly in late July.

e. Autumn greenhouse celery.

Planting in early to mid-September, seeds must be sown after low temperature germination, can be soaked for 24 hours, rub the seeds by hand, in order to rub off the inhibition of germination substances on the seed coat, and then put in the environment of 17 20 to germinate for 6 7 days, can be put into the well water surface 50 cm place to germinate. Sow seeds when they first sprout, and do a good job of shade and rain protection in the seedling shed.

f. Early ripening cabbage.

Early maturing and heat-resistant varieties such as "Xiaoza 56" and "Betty" are selected and harvested and marketed around the National Day and Mid-Autumn Festival. It is necessary to apply sufficient base fertilizer, prepare the land finely, water and cool down between the rows after sowing, and prevent virus diseases, aphids, cabbage worms and other pests and diseases from the seedling stage.

g. Autumn stubble open-field carrots.

Sowing began in mid to late July, and high-quality and high-yielding varieties such as "Hongxin 228" with beautiful root shape and three red skins, pulps and cores were selected. 4000 kg of well-rotted and finely crushed high-quality organic fertilizer or 3000 kg of commercial organic fertilizer are applied per mu, and after intensive cultivation, they are made into high furrow sowing, and the seeds are evenly sown, and about 300 grams of seeds are used per mu.

In view of the impact that the recent weather may have on the fruits and vegetables of the facility, measures should be taken in time before the arrival of snowfall and cold wave weather, and various tasks such as "windproof, heat preservation, antifreeze, disease prevention, and increasing greenhouse light" should be taken. 1.Before the arrival of cloudy and snowy days, melons and fruits should be picked early, and new high-fat film + root spirit should be sprayed to prevent pathogen infection, so that nutrients can flow back to the root system, promote root growth, and enhance the ability of plants to resist adverse environments.

Watering and topdressing should be stopped in the greenhouse on cloudy days, so as not to cause crop roots and aggravate the occurrence of diseases. 2.In the case of even cloudy days, as long as the temperature is not very low, the grass should be properly uncovered and try to scatter light as much as possible.

At the same time, a reflective curtain can be hung at the back of the greenhouse to enhance light and temperature. 3.If the weather is clear after continuous snowfall, the cover cannot be completely removed, and it should be removed successively to prevent "flashing seedlings".

After peeling, it is necessary to pay attention to the changes of crops, and when wilting occurs, it is necessary to immediately cover the grass and spray a new high-fat film to shorten the seedling period. After the seedlings have recovered, the grass is removed, and this is repeated for two or three days, and then transferred to normal management. 4.

Pay attention to heat preservation and heat properly. Multi-layer covering and insulation, that is, covering double layers of grass outside the shed film; If the temperature in the shed is lower than the minimum temperature required for the crop, the room temperature can be appropriately increased by auxiliary heating, but the indoor temperature should not be raised too high to affect the normal development. 5.

Pay attention to windproofing. Before the arrival of windy weather, it is necessary to check the fixing of the plastic film, the laminating line or the pressing rod must be fixed firmly, and the straw must be covered and pressed tightly, and the damaged shed film must be repaired and perfected. (China Plant Protection Network).

Warm up and adjust to the appropriate environment for the crop.

Sowing is available in mid to late November

1.Tomato. 2.Eggplant, pepper:

If sowing leafy greens:

1.cabbage, broccoli;

2.Greenhouse spinach, pea seedlings, greens, sowing period from late November to early December, greenhouse greens in late November, live broadcast in late November, can also be cultivated seedlings. In mid-December, varieties can be planted in winter evergreen, slow in February or red and bright spring, etc., and pea seedlings can be sown from late October to early November.

Field management: Vegetable production began to be transferred to winter sowing management, mainly to protect against cold and keep warm in winter, especially to strengthen the temperature and humidity control of nightshade vegetables at the seedling stage, and pay attention to the coordination of heat preservation and humidity reduction (ventilation).
