Planting time and method of green stem vegetable

Planting time: it can be planted all year round, but it is better in autumn and winter, and it is generally suitable to be planted indoors in winter in the north. Select varieties: select varieties with disease resistance and high yield according to different seasons. Soil preparation and trenching: the soil on the border should be fine, uniform and flat, and the ditches and ditches should be connected. Sprinkler irrigation and inter-seedling: sprinkler irrigation twice every morning and evening before emergence. Scientific fertilization: heavy application of base fertilizer and reasonable topdressing. Timely harvest: when it grows to 10 leaves and 1 heart, it can be harvested.

First, planting time

Green stem vegetable can be planted all the year round, but it is better in autumn and winter, and it is suitable to be planted indoors in winter in the north. Green stalk is a kind of Chinese cabbage, with fewer leaves and more stems, and its stem is white like a gourd ladle, so it is also called ladle white.

2. Selection of varieties

1. In summer, we should choose varieties with high temperature resistance, disease resistance and high yield, such as Xia Di and Xia Fei, with a growth period of 30 days.

2. Select varieties with low temperature tolerance, disease resistance and high yield in autumn, winter and spring, such as Huaguan, Huajin and Jinpin, with a growth period of 50-60 days.

III. Land preparation and trenching

The main results are as follows: 1. First of all, deep ploughing the whole border into a long border (35 meters) with a width of 1.6 meters, a height of 0.2 meters and a width of 0.3 meters. The length and width are neat and beneficial to management, and the soil on the border should be carefully refined, uniform and flat, which is beneficial to improve the germination rate of seeds.

2, at the same time, dig a good drainage ditch around, the ditch width is 0.3 meters, the ditch depth is 0.3 meters, the ditch and the ditch are connected, which is conducive to drainage.

Fourth, sprinkler irrigation and inter-seedling

Sprinkler irrigation should be carried out twice every morning and evening before seedling emergence, and once in the morning or evening after seedling emergence, and from 2-leaf-1-heart stage to 3-leaf-1-heart stage, seedlings should be carried out to keep the distance between plants at 10-15cm, which is beneficial to plant growth.

V. Scientific fertilization

1. During the planting period, base fertilizer should be re-applied and topdressing many times. The base fertilizer can be applied with 48% ternary compound fertilizer 25kg and 12% superphosphate 50kg per mu.

2. Topdressing was carried out at 4 leaf 1 heart stage, 6 leaf 1 heart stage and 8 leaf 1 heart stage, respectively. 48% ternary compound fertilizer 20kg plus 46% urea 10kg was used each time. After application, it was necessary to pump water and spray irrigation to avoid fertilizer falling on the leaves and causing seedling burning.

VI. Timely harvesting

Generally, in the period of 10 leaves and 1 heart, it can be harvested and sold. If it is for sale in other provinces, you can stop spraying water one day before harvest, which is conducive to long-distance transportation. Generally, you can use a special harvesting knife to cut it from the 1-2 leaves of the base. Then put the vegetables neatly into the basket and sell them.

VII. matters needing attention

The main results are as follows: 1. Green stem vegetables like cold and cold, but are not heat-tolerant, and some varieties are more cold-tolerant. The suitable temperature for germination is 20 ℃-25 ℃, and the suitable temperature for growth is 15 ℃-20 ℃. Green stem vegetables are not very strict in light requirements, sufficient sunshine is conducive to robust growth, like light, too weak light will lead to overgrowth.

2. Green stem vegetables like to grow in a warm and humid environment and like water. If they are short of water for a long time, it will lead to poor quality and increase fiber content.

3. Green stem vegetables are suitable for cultivation on fertile and loose soil. In summer, water should be watered once every morning and evening, and every two days in spring and autumn. Watering should not be carried out at noon, which is easy to hurt roots and is not conducive to growth. Generally, sufficient base fertilizer should be applied before sowing.
