First of all, leafy vegetables

1, Chinese cabbage

(1) There are many varieties of Chinese cabbage in the north, including Chinese cabbage, small walnut grains, large walnut grains, Chinese cabbage with core and so on.

(2) Chinese cabbage is one of the main cultivated vegetables in southern China. Because it adapts to the warm, humid and rainy climate in the south, and it is dry and rainy in June in the north, which is not conducive to the growth of Chinese cabbage, we should carefully choose varieties when planting.

2. Lettuce; lettuce

(1) Lettuce has the characteristics of heat resistance, moisture resistance and strong disease resistance. It can be planted all year round, and it is easy to emerge after planting.

(2) Lettuce has good early maturity and fast growth, and can be harvested after being planted for about 2-3 months.

3. purplish red

(1) The growth temperature of amaranth is 23-27℃. When the temperature is lower than 20℃, seeds are difficult to germinate and plants grow slowly.

(2) Amaranth belongs to short-day vegetables, and it is easy to bolt and blossom under high temperature and short-day conditions. The north belongs to temperate monsoon climate, and the temperature difference between day and night is large in June, and the daytime temperature is suitable for amaranth growth.

(3) When planting, the soil should be deeply cultivated, and 2,000 kilograms of decomposed high-quality organic fertilizer should be applied per mu, and then the ridge should be leveled, with a width of 1 m and a ridge height of10cm. Mix the seeds and fine soil at the ratio of 5: 1, and then spread them on the border, with the amount of seeds used per mu being about 0.6 kg.

(4) After sowing for about 20 days, when the number of seedlings leaves exceeds 2, topdressing is carried out for 1 time. After 12- 15 days, the second topdressing was carried out. 1 After thinning, topdressing for the third time. The dosage of chemical fertilizer per mu is ammonium sulfate 15 kg.

4. water spinach

(1) Ipomoea aquatica is mainly planted in the northern dry land. When planting, 2500-3000 kg of decomposed organic fertilizer is applied per mu, or human excrement 1500-2000 kg, and plant ash 60- 100 kg is used as base fertilizer.

(2) Before sowing, soak the seeds in warm water of 50-60℃ for half an hour, then soak them in clear water for 20-24 hours, then take them out and clean them, and put them in an environment of 25℃ to accelerate germination. During this period, wash them/kloc-0 times a day until the seeds turn white, and then start sowing.

(3) Water spinach can be planted closely, with a row spacing of about 33 cm. After sowing, cover it with fine soil.

5. oil wheat vegetables

(1) Before sowing, apply 3000 kg of decomposed organic fertilizer, urea 10- 15 kg, diammonium phosphate 15-20 kg, and potassium sulfate 5- 10 kg as base fertilizer per mu, and then level the soil and make a border.

(2) Soak the seeds in clear water for 4-6 hours, then take them out, drain them, wrap them in gauze, and transfer them to an environment of 15-20℃ to accelerate germination, and wash them every day 1 time. After 2-4 days, if 60-70% of the seeds germinate, you can sow.

(3) When the seedlings grow 3-4 true leaves, they should be planted with the row spacing of 15? 15cm. After planting, irrigate the planting water, slow down the seedlings after 3-4 days, and flush with water 15 kg urea.

(4) Re-apply the tree-promoting fertilizer in the later stage, applying 30 kilograms of urea per mu, and spraying 0.2-0.5% urea solution or 0.2% potassium dihydrogen phosphate solution for 2-3 times during the growth period.

6.cabbage

(1) Chinese cabbage can be planted in March every year until August-September, and June is more suitable.

(2) After cabbage filling, fertilizer and water were attacked together to promote the growth of leaf bulbs. Generally, 1 double water can be poured in about 7 days, and nitrogen fertilizer or high-nitrogen compound fertilizer can be topdressing.

Second, fruits and vegetables.

1, cucumber

(1) Summer cucumbers such as Xiaqiushuang, Lufeng and Jinza No.2 can be planted in June. The sowing date of summer and autumn frost is from June to July, and Lufeng is from July to early August.

(2) Strong seedlings can be cultivated in large and small rows, with the spacing between large rows of 60-80 cm, the spacing between small rows of 50 cm and the spacing between plants of 25 cm.

2. Chili

(1) Pepper is a fertilizer-tolerant, drought-tolerant and waterlogging-tolerant crop. When watering, it is not advisable to use flood irrigation, but it is advisable to see the soil wet and dry.

(2) The growth cycle of pepper is long, and sufficient base fertilizer should be applied before planting. The base fertilizer is mainly decomposed farmyard manure, and the dosage per mu is 4000-5000 kg. In the later stage, a small amount of topdressing can be used many times.

Step 3: tomatoes

(1) Tomatoes are resistant to high temperature and drought, and can grow in places with little water.

(2) Tomatoes can be planted in May-June and August-September every year in the north, and bamboo sticks should be inserted during the planting process to ensure that the plants have a supporting point after fruiting, which can improve the yield and quality.

4. Bitter gourd

(1) Bitter gourd can be planted before and after the awn seed, and it takes about 80- 100 days from sowing to harvesting, and the whole growth period is about 3 months.

(2) The optimum temperature for the growth of Momordica charantia is about 25℃. If the temperature is too high, the leaves will be burnt; If the temperature is too low, bitter gourd is vulnerable to freezing injury.

(3) The planting spacing of bitter gourd should be about 60 cm. If the planting density is too thin, it is difficult to achieve the expected yield. If the planting density is too high, it will easily affect the later growth.

5, loofah

(1) Luffa is a wet-loving crop. During planting, water 1 time after each flower soaking to ensure that the soil will not dry when it is wet.

(2) Luffa needs more water after entering the peak growth period, so it should provide enough water at this time. If it is sunny, water 1 time every 6-8 days or so to keep the border moist.

(3) Luffa needs high temperature in the whole growth period, and the suitable temperature for its growth is 20-24℃, and the suitable temperature for fruit development is 24-28℃.

Third, other categories.

1, root vegetables

(1) Radish and other vegetables are the main vegetables. Summer radish can be planted in June, and the varieties can be Hongxiu and Xiayuwang.

(2) When planting, 3000-5000 kg of decomposed organic fertilizer, 50 kg of plant ash and 0/0-/0/5 kg of calcium superphosphate/kloc-are applied as base fertilizer per mu.

(3) When the cotyledons are completely spread out, carry out the 1 interval seedling, carry out the second interval seedling after the seedlings grow 3-4 true leaves, and start the seedling fixing after 4-5 true leaves grow.

(4) After the leaves enter the peak growth period, there is a great demand for water. At this time, the ground needs to be kept wet and dry. After the root system enters the peak growth period, the water supply should be uniform. Stop watering 5-7 days before harvest.

(5) After the seedlings grow 2-3 true leaves, topdressing should be done in time, and urea 10 kg should be applied per mu. The second topdressing was carried out in the fleshy root growth period, and urea 15-20kg and potassium sulfate 15kg were applied per mu.

2. Leguminous vegetables

(1) cowpea

① Summer cowpea can be planted in June, such as Xiangzhen 1, Ningxiang 3, Lianxiang 1, with row spacing of 60-80 cm and plant spacing of 25 cm.

(2) Dig 3000-4000 holes per mu, sow 3 seeds per hole, and use 4-5kg seeds per mu.

③ Tillage and weeding should be carried out before pod setting, fertilizer and water management should be strengthened after pod setting, and appropriate topdressing 1 times should be applied in the middle and late stages to prevent premature aging.

(2) Mung beans

① Mung beans can also be planted in June in the north. Mung beans have strong adaptability to the environment, and varieties with strong heat resistance and disease resistance can be selected before planting.

② When planting mung beans, it is necessary to prepare loose, fertile soil rich in trace elements, which is beneficial to root development.

3. Cauliflower

(1) planting time

① Autumn cauliflower: In warm areas, the sowing date is from mid-June to mid-July; In mild areas, the sowing time is from early June to early July; In warm and cool areas, the sowing time is from mid-May to early June.

② Winter cauliflower: In warm areas, the sowing period is from mid-August to early September; In mild areas, the sowing time is from mid-July to mid-August; In warm and cool areas, the sowing time is from late June to mid-July.

(2) Planting method

① Choose the plot with high terrain, deep soil layer, loose and fertile soil, good irrigation and drainage performance and planting non-cruciferous vegetables as the planting land.

② Apply 2-3 cubic meters of decomposed high-quality organic fertilizer, 25-30 kilograms of 45% NPK compound fertilizer and 2.5-3 kilograms of agricultural borax as base fertilizer.

(3) Tillage the soil and level the boundary, the length and width of which are 10 m and 1.3 m respectively. Drainage ditch shall be excavated between the boundaries, with a depth of 15-25 cm.

(4) When the seedlings grow to 4-5 leaves, transplanting and field planting are started, with 2 rows per border, plant spacing of 50-55cm, row spacing of 50-60cm and planting density of 1500- 1700 plants/mu.

⑤ After planting, apply 1 diluted human excrement and urine. If the weather is dry, water 1 time every 2-3 days.
