Artificial cultivation of purslane
The purslane, also known as long-lived grass, sour rice, and melon seeds, is an annual wild vegetable. Its taste is slightly acidic, cold and smooth, and has the effects of clearing heat and detoxifying, cooling and smoothing the stomach, and reducing stomach and stomach. It has a good effect in preventing cardiovascular diseases and treating dysentery. The purslane is very widely distributed, often wild in the field hard, ditch, roadside and various dry land, in recent years, with the increase in people's consumption, has begun to turn into artificial cultivation. First, the cultivation conditions purslane hi hi temperature, high humidity, drought tolerance, resistance to pods, with positive, suitable for cultivation in a variety of fields and slopes, with neutral and weak acidic soil is better. The germination temperature is 18°C, and the optimum growth temperature is 20~30°C. When the temperature exceeds 20 °C, sowing can be staged and successively listed. Protected cultivation allows for annual production. Second, the breeding method of purslane breeding methods are seed propagation and cutting propagation of two kinds: (1) seed breeding. There is no artificially cultivated cultivar in purslane. Therefore, the seed used for seed propagation is the species that is retained at the first year from the field collection or cultivation. The seeds of the seeds are extremely small, the preparation must be fine, and the soil is kept moist after sowing. The seedlings can emerge in 7 to 10 days. (2) Cut propagation. Cutting branches are collected from the seedlings or wild seedlings of the year, and collected from strong and vigorous plants with strong branches and strong growth. Each section should have 3-5 knots. Before the cutting, the whole soil is finely grounded, and a sufficient amount of farmyard manure is applied in combination with the site preparation. Cutting density (line spacing) 3cm5cm, cutting depth of about 3cm into the soil, after insertion to maintain a certain degree of humidity and appropriate shade, can survive a week. Third, field cultivation and management sowing or cutting 15 to 20 days can be moved into the field cultivation, cultivation area is small, can also be directly inserted into the field. Before transplanting, the fields will be plowed, combined with 1500kg of fully decomposed human or animal manure or 15~20kg of ternary compound fertilizer per 667m2, then the 1.2m wide open hatches, 12cm20cm plant spacing, planting water after planting root water . In order to ensure the survival rate, transplanting is best done on a cloudy day. For example, transplanting on sunny days, shading measures should be taken within two days after planting, and watering should be done once a day in the evening. After transplanting, sufficient base fertilizer can be applied as required, and no fertilizer can be used in the early stage. , After each collection of 1 or 2 times to chase a thin person, animal and feces water, the formation of buds should be promptly removed in order to promote the pumping of vegetative shoots. When drought, water and drought are appropriate. During the whole reproductive period, purslane has very few pests and no spraying is required. 4. Harvesting of commercial vegetables The harvesting standard of purslane commercial vegetables is twigs 10 to 15 cm long before flowering. If harvesting is too late, not only tender shoots will grow old, food value will be poor, but also affect the next branch's pumping and annual production. Once harvested, it can be harvested every 15 to 20 days. This can be extended until mid-to-late October. Production generally adopts batch and batch recovery in stages. V. Seed and Seed Cultivation The plots of purslane seedlings shall be set out from the plots where commercial vegetables are produced at the beginning. The cultivation and management measures are the same as those for commercial vegetables. The difference is that the cultivated plots will not be harvested. Dishes are allowed to bloom, blossom, and seed naturally. 25 to 30 days after flowering, when the pods (species shells) are yellow, the seeds are mature and should be harvested in time, otherwise they will be scattered on the ground. In addition, some plants can be selected at intervals in the field where commercial vegetables are produced, and they can be scattered on the ground after naturally flowering and seeding. In the spring of the second year, the seedlings were naturally germinated and then densely replenished for production.
