How should out of season choy sum be grown? When is the best time to harvest?

Generally, he will choose to plant at intervals, so that he can actually increase the yield, and in general it has received a lot of attention, welcome, and the yield is relatively rich, and it is generally collected at the beginning of summer.

As long as it is well controlled, everything else at this temperature is the same as usual, depending on the growth cycle of the plant, and when it is time to harvest.

Four seasons cabbage is easy to plant, when planting, we should pay attention to the choice of planting season and variety, when sowing seedlings to choose sunny and warm weather sowing, summer high temperature season to cover shade net or straw, planting to grasp a reasonable density, fertilizer and water management to grasp well.

Four seasons cabbage is still very easy to plant, and it is also very nutritious, in the market is also better, four seasons cabbage in the planting or to pay attention to insect control work, this kind of vegetables are particularly easy to attract insects, do a good job of watering on it.

It is not easy to plant, planting this plant must control the temperature in the greenhouse, but also control the humidity, must be fertilized frequently, must be often pesticide, pay attention to keep warm.

It is difficult to grow, because the temperature and humidity requirements of seasonal vegetables are very large, so in the process of planting, we must pay attention to controlling the temperature and humidity.

This vegetable is easy to grow and sells well, so be careful when planting it, you can't water too much water at first, because the plant is annoying.

Very difficult to grow. When planting, you must choose the right temperature, only the right temperature to grow the four seasons cabbage will be very good.

1. The planting time can generally be cultivated in spring and autumn, and the cultivation of cabbage sum is mostly in autumn. The planting time varies slightly depending on the place, the northern region chooses to sow in August and September, the Yangtze River basin and the southern region choose to sow in September and October, and the southern region can be planted in all seasons in the southern region.

2. Harvest time. It can be harvested 2 months after planting.

3. Requirements for soil. It must be loose and breathable, easy to drain and irrigate, and be a sandy loam with a high organic matter content.

4. Drenching fertilizer. It is best to use well-rotted pig manure or chicken manure.

5. Watering. It is recommended to water the cabbage every 2-3 days, and irrigate it in time after planting. During the growing season, it is recommended to water once every 3-5 days, and pay attention to keeping the soil moist.

6. The auspicious time for sowing early-maturing cabbage is from May to September, and this season is just high temperature and high humidity, and there are many heavy rains, so it is suitable to take the way of live broadcasting. Medium-ripe choy sums are usually sown in March-April or September-October. Late-ripening choy sums are usually sown from November to March of the following year, and it is better to soak the seeds in warm water to promote germination.

1. Choy sum is generally planted around March in spring or August and September in autumn, and the time when choy sum is generally planted during this time period is also the best period for the growth of choy sum, which has a significant increase in yield.

2. Choose varieties: There are many varieties of cabbage, you can buy several kinds of cabbage in the market, if you want to plant, you must first according to the local climate, soil and other factors. In addition, it is necessary to consider the characteristics of the variety, which is easier to raise, the yield is higher, and the varieties suitable for local planting are selected in all aspects.

3. Reasonable dense planting: when the seedlings grow 4-5 true leaves, they should be planted in time, and the density of planting should be determined according to the variety form, planting time and planting purpose. Generally, the early-maturing varieties planted in summer are mainly harvested cabbage, and the long cycle of raw tara is short and the growth is fast, so the suitable plant row spacing is 13 cm to 16 cm.

The mid-late maturing varieties planted in summer and autumn have a long growth cycle and large plants, so they are not suitable for planting too densely, and the plant row spacing is 16 cm to 20 cm.

4. Timely harvesting: the harvest of cabbage should also be strictly mastered, generally in the rapeseed sprout and the tip of the high leaf flush, the bud is the appropriate period for harvesting, and to harvest the side, the main flower can be cut at the base 2-3 section, and the harvester can be cut 1-2 knots lower. If the harvest is too early, the rapeseed sprouts are not ripe and grow, the yield is low, and the harvest is too late, the rapeseed sprouts are aging and the taste is poor, which affects the quality and commerciality.

We must choose the right planting temperature, the temperature must be kept at about 23 degrees, and it is necessary to choose fertile soil, Zhengkong must be watered and fertilized in time, choose high-quality seeds, and strengthen the seedling cultivation work of seed clusters.

First of all, you need to build a greenhouse, and then ensure that the temperature in the greenhouse is above 20 degrees, and you can plant it out of season.

First of all, we should choose high-quality varieties, and then we should also water and fertilize in time, maintain the right temperature, the temperature must be controlled at about 23, improve the fertility of the soil, and ensure that the light is sufficient, and do a good job of drainage and ventilation.

Planting method Sow the treated water spinach seeds according to the row spacing of 30-35 cm, and then cover them with a thickness of 1-2 cm.

Choy sum, also known as cabbage, belongs to the Brassica genus of the cruciferous family, which can be planted once a year. The best time to sow choy sum is from early February to late March, and it can also be sown from early August to mid-September, when the temperature is between 15 and 25 degrees Celsius, which is a good time to promote the growth and development of the plants. Leaks are missing.

Cabbage careless sowing method.

1.Seedlings:When sowing cabbage, the soil needs to be trimmed to ensure that the soil is in a relatively loose state, so that the seedling rate of soil seeds will be higher, and at the same time, relatively thick shoots are selected for seedling.

2.Trim:When sowing cabbage, it is necessary to remove the residual flowers in time, and prune the branches and leaves that grow too densely and the sick dead branches to ensure that their nutrition can be maintained at the same time.

Key points and tips for planting choy sum.

1.Fertilization:The first fertilization is after planting, the second fertilization is carried out when the cabbage is gradually formed, and then it is fertilized after each harvest.

Recombustion. 2.Watering:When planting choy sum, it needs to be watered, and the moisture in the field should be kept at about 70%, and at the same time, it needs to be watered every other week or so.

Choy sum is usually planted in March or September, when it is at its peak, but now it can be grown all year round. The main purpose of live broadcast is to sprinkle the seeds evenly on the ground, and wait until the seedlings emerge to carry out seedling thinning and replenishment. Strip sowing is done by opening a small furrow, and then the seeds are sprinkled into the furrow to cover the seeds.

Northern cabbage is mainly planted in the open field from April to October, and can be planted in the greenhouse with four seasons a year, mainly in the market.

Origin of choy sum. Choi sum, also known as Chinese cabbage, is native to China, and its main production areas are distributed in Guangdong, Shanghai, Zhejiang, Jiangsu, Anhui and other places.

Choy sum planting method.

The main purpose of the live broadcast is to sprinkle the seeds evenly on the ground, and wait until the seedlings emerge to carry out the seedling wisdom grip and replenish the seedlings. Strip sowing should open a small ditch, and then sprinkle the seeds into the ditch to cover the seeds, and carry out the seedling replenishment in time.

Key points of cabbage planting management.

Fertilization of cabbage sum is generally after planting, the second fertilization when the cabbage begins to form, and the fertilization should be carried out after each harvest of cabbage, and the fertilization should be combined with weeding to reduce the loss of nutrients.

Soil preparation and fertilization: water spinach has a fast growth rate, strong branching ability, and needs more fertilizer and water, so it is advisable to apply sufficient base fertilizer. Fertilizer and soil are mixed evenly, and they should be applied to the whole furrow a few days in advance, and then sprayed on the surface of the new high-fat film soil, which can protect moisture and waterproof evaporation, sunscreen and drought resistance, heat preservation and antifreeze, prevent soil layer compaction, suffocate and isolate the source of diseases and insects, and improve the emergence rate.

Soaking seed germination: the seed coat of water spinach seeds is thick and hard, if it is directly sown it will germinate slowly due to low temperature, so it is advisable to carry out germination, soak it in warm water for 18-20 hours after dressing with a new high-fat film, and then wrap it in a sand cloth and place it in the germination box of 30 to promote germination, when the seeds have 50 -60 white can be sown.

Sowing: water spinach can be sown or strip sowing, the amount of seeds per mu is kilograms, after sowing, cover about 1 cm thick with fine soil, strip sowing can be horizontal on the furrow surface of a shallow ditch of 2-3 cm deep, the furrow distance is 15 cm, and then the seeds are evenly sprinkled in the furrow, and then covered with fine soil, and then covered with a shading net, and then watered, after the emergence of seedlings, the shading net can be uncovered.

Fertilizer and water management, pest and disease prevention: water spinach is a crop harvested many times, so in addition to applying sufficient base fertilizer, it is necessary to carry out multiple phased top dressing, spraying targeted drugs and new high-fat film, greatly improving the utilization rate of pesticides and fertilizers, not afraid of sun exposure and evaporation, can adjust the amount of water absorption, drought and rain.

Growth period: Spraying strong stems during the flourishing period of the plant can make the plant stem thick, the leaf hypertrophy, the leaf color is fresh and tender, the plant is lush, and the natural taste is strong. At the same time, it can improve the ability to resist disasters, reduce the amount of pesticides and fertilizers, and reduce residual toxicity.

In order to improve the yield and quality of the next time, it is necessary to achieve timely topdressing after picking.

Water spinach. Water spinach, formerly known as Yongcai, is also known as rattan vine vegetables, bracken vegetables, cabbage, macaroni, heartless cabbage, urn vegetables, empty tube vegetables, bamboo leaf vegetables, white trumpet-shaped flowers and their stem center is empty, so it is called "water spinach".
