Planting technique of Rabdosia angustifolia

Portulaca oleracea is also called Portulaca oleracea, five-element grass, longevity vegetable, five-square grass, pig fat vegetable, Portulaca oleracea, etc., it is an annual herb of Portulaca oleracea, born in sunny places such as field roadside and garden ruins, and the whole grass is for medicinal use. it has the function of clearing heat and dampness, detoxification and detumescence, anti-inflammation and diuresis, and tender stems and leaves can be used as vegetables. Let's take a look at the planting technology of Portulaca oleracea.

Growth habits of Rabdosia angustifolia

Rabdosia angustifolia likes high humidity, drought and waterlogging tolerance, and is positive. It is suitable for cultivation in all kinds of fields and slopes, especially in neutral and weak acid soil. The germination temperature is 18 ℃, and the optimum growth temperature is 20-30 ℃. When the temperature exceeds 20 ℃, it can be sown by stages, appear on the market one after another, and protected cultivation can carry out annual production.

Propagation method of Rabdosia angustifolia

1. Sowing and propagation: the seeds used for seed propagation of Portulaca oleracea are collected from the field or cultivated in the first year. The seeds are very small, and the soil preparation must be fine. Keep the soil moist after sowing, and the seedlings can emerge in 7 days and 10 days.

2. Cutting propagation: the cutting branches are collected from the sowing seedlings or wild seedlings in the same year, and it is better to collect from the strong plants with many branches and prosperous growth, with 3-5 nodes in each segment. Fine soil preparation before cutting, combined with fully mature farm manure. The cutting density (spacing between rows) is 3cm, the depth of cuttings is about 3cm, keep a certain humidity and proper shade after cutting, and survive after a week.

Planting technique of Rabdosia angustifolia

The main results are as follows: 1. Soil preparation and fertilization: Rabdosia angustifolia can be planted in the field 15-20 days after sowing or cutting, and can be directly cut into the field when the cultivation area is small. Ploughing the soil before transplanting, combined with land preparation, apply 1500 kg of fully mature human dung or 15kg 20 kg of ternary compound fertilizer per mu.

2. Box-opening transplanting: Rabdosia angustifolia was opened by 1.2 meters wide after fertilization, planted according to the row spacing of 12 cm × 20 cm, and poured through the root water after planting. In order to ensure the survival rate, transplanting should be carried out in a cloudy day. Shading measures should be taken within 2 days after planting and watered once every evening.

3. Field management: after applying sufficient base fertilizer according to the requirements, Rabdosia angustifolia can not be topdressing in the early stage, and after each harvest, the buds should be removed in time to promote the emergence of vegetative shoots and properly watered to resist drought. During the whole growth period, there is very little harm to diseases and insect pests, and generally there is no need for spraying.

4. Timely harvest: the harvest standard of Rabdosia angustifolia commercial vegetables is 10-15 cm long shoots before flowering. If the harvest is too late, not only the twig will become old and the edible value will be poor, but also the next branch and the annual yield will be affected. After one harvest, it can be harvested every 15 to 20 days, so it can be extended to the middle and late October, and the production is generally harvested in batches by stages.

5. Seed retention and seed collection: the plots where seeds are retained should be drawn from the plots where commercial vegetables are produced from the very beginning, and the cultivation and management measures are the same as those of commercial vegetables production, except that the plots with seeds are not harvested, but are allowed to branch, blossom and seed naturally. 25-30 days after flowering, when the capsule is yellow, the seeds are ripe and should be harvested in time, otherwise they will be scattered on the ground.
