Healing vegetables, also known as heart dishes, are perennial herbaceous fleshy roots, edible stems and leaves, and artificially sown and planted once for 20 consecutive years. It is a health-friendly wild vegetable. Healing vegetables are shade-tolerant, drought-tolerant, cold-resistant, with less pests and diseases, stronger growth, and more branches. Plant heights generally range from 20 to 28 centimeters. They are soil-free, easy to plant, easy to live, and easy to manage. After eating, people have various effects such as lowering blood pressure, lowering blood fat, promoting blood circulation, and removing blood stasis. China Agricultural Net is now introducing artificial high-yielding cultivation techniques for Yang Xin Cai in the Yangtze River Valley as follows:
One, cutting seedlings
The Chinese cabbage has strong resistance to stress and strong vitality. Although it can adopt seed propagation and propagation, the cutting propagation is easier. It can be carried out in spring, summer, early autumn and winter greenhouses. The old ripening branches of the vegetables can be planted directly in the cultivated land, but in order to arrange the cornices scientifically, the seedling management is well done. The production is generally from the middle and late March to early April, from the protected areas, or in 5 In mid-late and late-September and late-September, pick up old mature shoots from cuttings and grow cabbages. The nursery should select a land with high topography and well-drained land, and spread clean sand with 10cm thick, 1m wide and 10~40m long as cutting seedbeds. How to choose pesticides for greenhouse vegetable cultivation site per acre Area 65~70 meters 2. Cut 10 to 15 centimeters long, old mature branches with lignified base, remove the top stems and base leaves, leaving 3 to 4 leaves per cutting, 30 to 50 roots into 1 The base is soaked with 50 mg/kg rooting powder solution for 18 hours, inserted into the seedbed at a spacing of 5 cm, 5 cm deep, then irrigated with water, smashed over a small shed to cover the shade net, and suitable shade seedlings, 7~10 Days can survive, 20 to 25 days can be transplanted and planted. Water in the seedlings during drought.
Second, the application of base fertilizer
The dryland suitable for growing crops can be cultivated with Chinese cabbage, but the fertile sandy loam cultivated land and the loam cultivated land are conducive to its high yield. In advance, the arable land will be deep-rooted and dried, and 2,000 kg of decomposed pig manure or 100 kg of cooked vegetables and 50 kg of ternary compound fertilizer (15% each of N, P, and K contents) will be applied per acre as basal fertilizer. According to the width of 2 meters, the ditch is opened and the ditch is 30 centimeters deep and 20 to 40 meters long. The gutters and gutters are to be opened and the surface is to be planted.
Third, transplant planting
Set the planting ditch at a spacing of 25 centimeters, that is, open 5 furrows per pound, apply 1,000 kilograms of beef manure or 50 kilograms of perishable vegetable cake per acre, apply the fertilizer into the furrow, and fully mix the fertilizer with the soil. Planting at a distance of 15 cm. When planting from the seedbed with soil from the seedlings, each hole planted 2 to 3 seedlings, planting depth of about 5 cm, after pouring enough water to plant, and then cover the fine soil for suppression, pouring water. The total number of colonization per acre was 9500 to 10000 points and the total number of plants was 22,000 to 25,000. If there is no nursery condition, we can collect 10 to 15 cm long, mature wooded branches at the base of the spring and autumn season, remove the top tender stems and the base leaves, leaving 3 to 4 leaves per cutting, planting and colonization. The method is the same as above.
Fourth, field management
1. Fertilizer management After planting, less fertilizer should be applied to the top dressing. Normally, top dressing is applied once a month or with water, and 10 kg of urea and 3 kg of potassium dihydrogen phosphate are applied per acre. Before wintering or returning to green, 2,000 kg of fertilizer or 50 kg of ternary compound fertilizer is used per acre. For each harvested time, 10 kg of potassium chloride or 100 kg of plant ash should be topped up in time for each acre to promote branching and increase yield. If the soil is dry, it should be watered in time. The water must be poured thoroughly;
2. Weeding and weeding should be done immediately before weeding, before returning green in the early spring, and after each harvest.
3. Manage the open-grown vegetables during the winter and over the summer. In the 20 days before the frost fall, except for the base of the upper part of the plant, which is kept 10 centimeters away, all the upper part is cut off, then irrigated, and covered with a layer of 3~5 cm thick rice. Wheat straw can safely winter.
Protected cultivation of vegetables, in winter, there must be a plastic canopy covered with plastic sheds and non-woven covered cold protection measures. In case of severe cold weather, straw curtains should be covered at small arches at night; in case of snowfall, it should be timely. Clean the snow area of ​​the shed to avoid squeezing the shed; the daily management of winter is still based on scientific and rational ventilation. Watering vegetables in greenhouses should pay attention to the cultivation of cultivated vegetables. During the hot summer seasons from June to September, shade nets should be used to cool the roofs.
V. Harvesting and Processing
When the plant height of the cabbage is more than 20 cm, it should be harvested in time. There are two kinds of harvesting methods. One method is unified harvesting, which is to use a guillotine knife to cut the stems and leaves at one time horizontally on the basis of three or four nodes at the base of most of the shoots. Generally, they are cut once every 60 days. Each mu yield is about 4000 kg. The open field cultivation can be cut 4 times a year, and the cultivation ground can be cut 6 times a year. Another method is to harvest in batches in stages, firstly harvesting dense, thick and tender stems and leaves, allowing the thin and sparse stems and leaves to continue growing, and then gradually harvesting them later. The total annual production of the two harvesting methods is basically the same. The harvested stems and leaves can either be directly marketed or sun dried for consumption or tea.
