There is an art to clever vegetable growing: these cultivation techniques are worth mastering
?1. Growing vegetables at scale That is, expanding the area to create scale. In recent years, the practice of vegetable production has proved that only with scale is there a market; without forming a large scale, it is hard to solve the problem of difficulty in selling vegetables. For remote rural areas far from large and medium-sized cities, some "long-leg" vegetables that store and transport well should be developed appropriately, such as garlic, Welsh onion, onion, and potato; these vegetables carry relatively lower market risk.
?2. Growing vegetables in three dimensions Three-dimensional growing can rationally use time, space and soil nutrients and raise the multiple cropping index. For example, spring cucumber intercropped with oyster mushroom in greenhouses, summer cowpea intercropped with straw mushroom, watermelon relay-cropped with sweet pepper; on the trellis grow loofah, chayote and pumpkin, while below the trellis are grown cilantro and bok choy; under fruit trees are grown shepherd's purse, bok choy, spinach and so on.
????3. Growing specialty vegetables Specialty vegetables such as celeriac, chicory, Brussels sprouts, super-sweet corn, vegetable sweet potato, fruit radish and dandelion, with their relatively small cultivation area and high commercial value, hold an irreplaceable market; they can be introduced (trial-grown) locally according to conditions first and then promoted.
4. Growing health-promoting vegetables Some vegetables have health-care and beauty benefits, such as the small red pumpkin with a single fruit weight of only 1-1.5 kg, whose skin is deep red and flesh is powdery sweet, and which has good effects on lowering human blood lipids, enhancing gastrointestinal peristalsis and reducing cerebral arteriosclerosis; red hyacinth bean and winged bean can help gastrointestinal digestion, clear heat and remove dampness; lettuce (leaf lettuce) has effects such as pain relief, hypnosis and lowering cholesterol; shepherd's purse has effects such as improving eyesight, stopping bleeding, cooling, reducing fever and promoting urination; water spinach has effects such as clearing heat and detoxifying, promoting urination and stopping bleeding; bitter melon has effects such as relieving summer heat, clearing heat, promoting urination and increasing appetite. For these health-promoting vegetables, production can be appropriately expanded.
5. Growing wild vegetables China is one of the countries with the most vegetable species in the world. At present about 160 kinds of vegetables are cultivated, and there are more than 400 kinds of edible wild vegetables, most of which have not yet been developed and utilized.
6. Growing colored vegetables Colored vegetables are spoken of in comparison with ordinary green vegetables. For example, the skin of ordinary tomato fruit is red, while the colored varieties are golden yellow. Ordinary cabbage is white-green, while the colored varieties are light purple. Also, sweet waxy corn, purple sweet pepper, red choy sum, as well as some melon and bean vegetables with small fruit, novel shapes and unusual colors, also belong to this category. Although they are not the mainstream products of today's edible vegetables, because they are full of extraordinary charm and can stimulate consumers' curiosity, they can continuously add new varieties to the vegetable market and accelerate vegetable circulation.
7. Growing ornamental vegetables Ornamental vegetables such as the dainty and exquisite golden pearl tomato, the winding and graceful snake gourd, and the long-necked gourd that looks like a hammer but is not, can all serve as preferred varieties for sightseeing agriculture.
8. Growing pollution-free vegetables To meet people's demand for pollution-free food, pollution-free cultivation techniques for vegetables should be vigorously promoted and standardized production implemented. At the same time, brand awareness should be established, trademark registration should be carried out for vegetable products, and where conditions permit, pollution-free agricultural product certification should be implemented as early as possible, so as to seize and expand market share.
