Balcony vegetable planting--cabbage

Chinese cabbage, also known as Brassica campestris, Cruciferae Brassica, annual or biennial herbs. Suitable for sowing in the warm areas of the south, it is one of the specialty vegetables in the south of China.

The heart of Chinese cabbage is tender in quality, sweet and bitter in taste and rich in nutrition. The edible part per kilogram contains 13 grams of protein, 1 grams of fat, 22 grams of carbohydrates, 410 grams of calcium, 1350 milligrams of phosphorus and 13 milligrams of iron. Carotene 1 mg 13.6 mg, riboflavin 0.3 mg, nicotinic acid 3 mg, vitamin C790 mg.

Key points of balcony cultivation techniques of Chinese cabbage

1. Variety selection

There are three types of varieties: early maturing, medium maturing and late maturing. Early-maturing varieties, such as 49 cabbage, can be harvested in 35 days, and medium-and early-maturing varieties can be harvested in 60 days. Late-maturing varieties should be selected in winter and spring.

two。 Cultivation environment

Chinese cabbage likes mild climate, the balcony light is good, and the growth is suitable for 15 ℃ ~ 25 ℃. Balcony flower terrace or balcony planting basin can be cultivated.

3. Cultivation season

The growth cycle is short and multiple planting and harvesting can be realized. In the south, it can be sown every year, mainly in spring, summer and autumn.

4. Sowing management

(1) substrate treatment before sowing.

1-2 days before planting, keep the original state of the basin matrix unturned, wet the matrix to the bottom with clean water, and make the matrix moist. Substrate treatment and sowing can also be carried out at the same time, but the substrate is too wet to cause rotten seeds and too dry to cause irregular germination and emergence.

(2) sowing

On the substrate poured with sufficient water, the seeds were sown uniformly or through pry holes into the substrate. After sowing, the seeds should be covered with matrix soil for about 1 cm and watered thoroughly.

5. Administration and Management

The main results are as follows: (1) Water management: there are differences in plant water requirements in different climatic regions and different seasons, so it is appropriate to keep the soil moist, avoid being too dry and too wet, and provide sufficient fertilizer and water when most plants bud and begin bolting. Avoid watering at noon in the hot season and control the amount of water in the week before harvest.

(2) and time seedlings: when the cotyledons were unfolded, the first seedlings were carried out in time, and then the seedlings were fixed according to the row spacing as the seedlings grew. The plant-row spacing of early-maturing varieties was 12-13cm, and that of middle-late-maturing varieties was 15-16cm.

(3) fertilization management: the substrate has its own nutrients, which can be irrigated with organic fertilizer fermented liquid made from rice panning water, pericarp, kitchen residue and other materials commonly used in daily life.

(4) pest control. In principle, pesticides are not used. When yellow leaves, diseased leaves and rolled leaves are found, they should be removed in time. When aphids are found, garlic, onions and other mashed juice can be used to dilute and spray.

6. Harvest

When the cabbage heart "Qikou flower" (the height of the bolting reaches the same height of the plant), it begins to be harvested. After harvesting the main moss, continue to harvest the side moss. If the lateral moss is collected, the main moss is cut at the base of 2-3 leaves.
