Green vegetables we buy all the year round, many children do not like to eat vegetables, through different cooking methods can also make them change their minds. Today, the editor would like to introduce to you the method of growing green vegetables in the four seasons. Let's take a look at it.

The planting method of green vegetables in four seasons

I. cultivation methods of green vegetables in spring

1. Varieties: green vegetables cultivated in spring should choose varieties with strong winter nature, so that it is not easy to bolt. Varieties such as March slow, April slow and May slow are generally selected in Shanghai.

2. Raising seedlings: make the nursery land into a border with a width of 2 meters (even ditches), and use 1000 kg of rotten organic fertilizer per mu. Sow seeds from early to late October with a seed consumption of 0.3 kg per mu. Sowing should be uniform and steady after sowing. After emergence, the seedlings were planted for 2 or 3 times, and the appropriate amount of topdressing was applied. When the seedling has 6 or 7 true leaves, it can be planted in the field.

3. Soil preparation: after ploughing in the field, 50 kg of special compound fertilizer for vegetables is applied as base fertilizer per mu to make a bed 2.5 meters wide (even ditches), which is to be planted.

4. the seedlings were planted slowly in March and late January in greenhouse, and slower in May than from early February to late March. The row spacing was 10 × 15 cm in March, 15 × 15 cm in April and 15 × 20 cm in May, respectively.

5. Field management: topdressing once after planting live trees, applying 5 kg urea per mu. Apply 7.5 kg urea per mu for the second time before closing. Pay attention to preventing aphids in March.

6. Harvest: the harvest of seedling in open field in March is slower than that from late February to late March, that in greenhouse in April is slower than that from late March to early April, and that in May is slower than that from late April to early May. Remove the root with a kitchen knife, and the clean vegetables are on the market.

2. cultivation methods of green vegetables in summer

1. Varieties: varieties with strong heat tolerance and good quality were selected as summer varieties, such as Kangreqing 3, Huawang, 605 and so on.

2. Soil preparation: 40 kg of special compound fertilizer for vegetables is applied per mu as base fertilizer to make a bed 2 meters wide (even ditches) to achieve deep ditches and high beds to facilitate drainage and irrigation.

3. Sowing: green vegetables (green vegetables cultivated in summer) were sown in batches from mid-June to early August, and sowed evenly. The amount of seeds used was determined according to the purpose of cultivation, and the amount of seeds used for cultivation was 2.5 kg per mu. The seed consumption of "one sowing and three selling" is 1.2 to 1.5 kilograms. The amount of seed used for vegetable seedlings is 1 kg. Insect control net and sunshade net can be used to cover cultivation in the whole process, so as to achieve the purpose of using less and no drugs.

4. Field management: green cabbage can be interspersed with seedlings when cotyledons are unfolded, keeping the distance between seedlings at a distance of 3 cm, and then between seedlings after the emergence of true leaves, the distance between seedlings is 12-14 cm. Fertilizer should be applied after each seedling, and 6 kg of special compound fertilizer for vegetables should be used each mu. The transplanted Chinese cabbage is generally sown in late July, the seedling age is 25 days old, the transplanting is selected in the cool weather, the seedlings are pulled in the afternoon, and planted after 3 pm, the density is 12-14 cm square. Watering should master the principles of light watering and frequent watering. Watering should be carried out before 8: 00 a.m. and after 5: 00 p.m., to prevent rotten vegetables. Attention should be paid to the control of aphids, cabbage insects and Plutella xylostella.

3. Cultivation methods of Chinese cabbage in autumn

1. Varieties: dwarf resistant green, Xinchangqing and other varieties which are more resistant to virus disease are generally selected.

2. Raising seedlings: reorganize the seedling land and sow seedlings in batches from the first ten days of August to the end of September, with a sowing rate of 0.5-0.75 kg per mu. Water once or twice a day after sowing. 2-3 times after emergence, the distance between the seedlings was 3 cm square.

3. Soil preparation is the same as spring cultivation.

4. Planting: the planting time is generally from early September to early November, and the row spacing is 20 × 25 cm. Irrigate the root water immediately after planting.

5. Field management: after living trees, use urea 5 kg per mu, and topdressing again before closing. Timely watering or irrigation in case of drought, pay attention to the prevention and control of aphids and viruses.

6. Harvest: according to the planting period, the harvest time is also different. If it is planted in September, it can be harvested in 25-30 days. Planted in the first and middle of October, harvested in about 40 days, planted in late October to early November, harvested in 45 days.

4. Cultivation methods of green vegetables in winter

1. Varieties: winter evergreen and slow February are generally selected.

2. Seedling raising: sowing and raising seedlings from late September to early October, the sowing amount is 0.4 ~ 0.75 grams per mu, and the seedling stage is properly fertilized.

3. Soil preparation: cultivated in the same spring.

4. Planting: the planting period of holly is from the beginning of November to the end of January of the following year. To avoid frost injury, the general row spacing is: 8 × 15 ~ 17 cm.

5. Field management: basically the same as spring cultivation, strengthen cold prevention measures, can be covered with non-woven floating surface.

6. Harvest: the growth of winter sowing green vegetables is slow, and it takes 80 to 90 days from planting to harvest, which can be advanced or postponed according to the market.
