Sowing and propagation method of wasp

Soil

The slightly acidic sandy loam with semi Yin and semi Yang, moist and rich humus should be selected for the cultivation of bee fighting vegetables, and the drainage of the soil is better. After the cultivation site is selected, base fertilizer can be applied to deeply turn and fine the soil

Intercropping weeding

When sowing in spring, small seedlings will grow around the first ten days of April. When weeding for the first time, seedling supplement can be carried out at the same time. At this time, the seedling root system grows slowly. It is necessary to loosen the soil slightly to avoid damaging the seedling root system

In June and July, the seedlings have come out and the root system has grown well. At this time, the second intercropping can be carried out

In the first ten days of September, the stems and leaves on the ground of the plant gradually stop growing and the flower buds begin to differentiate. At this time, the third intermediate tillage can be carried out to keep no weeds

Intercropping

At the end of April and the beginning of May, after the seedlings are ready, the seedlings can be interspersed appropriately according to the emergence situation, leaving strong seedlings and removing weak plants

Top dressing and soil cultivation

There is no need for topdressing in the early stage of growth to avoid excessive growth. In the later stage of growth, topdressing management should be strengthened. Topdressing should be combined with loosening the soil, covering the fertilizer on one side and cultivating the soil on the root of the plant on the other side, which can maintain the fertilizer efficiency of the soil

Watering

Fengdoucai is afraid of drought and waterlogging. It should be watered twice or three times in the spring drought, and be prepared for drainage when the rainy season comes

Leaf cutting ventilation

From June to August, it is in full leaf stage. Too dense leaves and poor ventilation and light transmission will affect the differentiation of plant flower buds and lead to diseases and pests. At this time, the overlapping leaves should be cleaned, and it is best to trim them with scissors. When breaking them by hand, it is necessary to avoid damaging the base of the plant< span>
