How to grow the necessary baby vegetables in winter with high yield? Introduction of four key skills!

Baby vegetables are small vegetables that look like Chinese cabbage with high nutritional value and are generally used to eat hot pot or stir-fry directly, so how to grow baby vegetables to get high yield? In fact, the method is very simple, to master the following four high-yield cultivation techniques.

1. Soil

Compared with Chinese cabbage, the cold tolerance of baby vegetables is relatively poor, so sowing as early as possible, if you wait until the weather is cold, it will naturally affect its growth, but you can plant some on the balcony, the balcony temperature is not very low, will not be affected by the temperature!

II. Fertilization

Before planting, choose a better soil, apply some organic fertilizer on the soil, and then mix it evenly, either bean cake fertilizer or bone meal or plant ash. If you feel that self-made fertilizer is troublesome, you can apply microbial fertilizer for vegetables and vegetables, which can provide sufficient nutrients for nitrogen fixation, phosphorus and potassium release! The vegetables grow better and better!

Third, sowing seeds

1. Sowing seeds

Sowing in early spring: in the south of the Yangtze River, raise seedlings in a greenhouse plus a small shed in February, it is best to use an electric hotline to heat up.

Autumn sowing: sowing seedlings in the Yangtze River basin from mid-late August to mid-September, and mulching with plastic film when raising seedlings and cultivating in late September. A 128-hole hole plate is generally selected to ensure that the seedlings have enough space for growth.

2. Seedling stage management

When 70% of the seedlings are unearthed, the daytime temperature should be controlled at 20: 22 ℃, and the night temperature should be at 13-16 ℃, in case the night temperature is too low and vernalization bolting. If the seedlings are raised in early February, when the seedlings have 3 leaves and 1 heart, they can be planted in the greenhouse or small shed with plastic film. Sown in late February, when the seedlings were 20-25 days old, planted in a small shed plus plastic film or plastic film cultivation.

Autumn seedlings are in a high temperature period, it is best to use shade seedlings, reduce direct sunlight, weaken the light, reduce the temperature, increase humidity, and create environmental conditions suitable for the growth of vegetable seedlings. It is appropriate to choose black sunshade net to cover. If the acupoint plate is put in the greenhouse, the sunshade net is directly placed on the roof or skeleton of the shed to make the acupoint plate form Hua Yin.

In summer, the land with good ventilation and dry drainage was selected to establish a seedling bed. If there are conditions in the high temperature season, the well water can be sprayed at the top of the protected facilities to form a water film, which can not only reduce the temperature, but also improve the air humidity. Generally, 5-7 days before planting, the seedlings are tempered by changing light and temperature. all the shading nets are removed and flooded once, so that the seedlings can adapt to the open field environment and be flexible according to the weather.

IV. Management

Baby vegetables grow very fast, and there is a great demand for water and fertilizer during the growth period, so pay attention to timely watering and let the soil be in a relatively humid state when planting. Baby vegetables have more leaves and evaporate quickly, so that they can grow better!

After the baby vegetable seedlings come out, they should be sorted out. If they are too dense, they need to grow between seedlings, so that each vegetable has enough light. In addition to watering, fertilizer is also very important. Proper use of some microbial agents, fruit and vegetable fertilizer, will work better!

Basically, doll vegetables are harvested 50-55 days after planting, and the tightness is 70-80%. Too tight is not easy to pack, and the outer leaves are removed. Each plant is processed into a net weight of 170-200g leaf balls, 3 in each bag, and then packed in 30 bags each. It can be transported and sold after pre-cooling.
