What are the leafy green vegetables that are easy to grow and do not need to be raised in advance?

Beans: soybeans, red beans, mung beans, beans, green beans, snow peas, lentils are very easy to germinate, and the emergence rate is high. Melons:

Cucumber, winter squash, pumpkin, loofah, zucchini melon, chayote. Ordinary seedbed seedlingsOrdinary seedbed seedlings, also known as cold bed seedlings, are a traditional way of raising seedlings. Its advantages are convenient materials, low cost and simple technology.

The disadvantage is that the temperature of the seedbed is low due to the lack of necessary environmental protection.

<> blood skin vegetables are called Guanyin Han cuisine in our place. Bloody cabbage is very suitable for lazy people to plant, and planting bloody cabbage does not require any skills, cut a piece of bloody cabbage directly into the soil to survive, bloody cabbage has a strong tillering ability, can slowly grow a large canopy. When raising cucumber seedlings, after the seeds are soaked in water, they are wrapped in gauze and placed here, paying attention to the need to be in an environment of 25-30 degrees, so that the germination is fast.

After 2-3 days, it will appear white, and then it can be sprinkled on the seedling land, and the soil should be soft, and you can sprinkle some fire ashes.

Water spinach is also called "cabbage" in our local area. Old farmers who have planted water spinach know that water spinach has a strong ability to regenerate (multiple stems and leaves), and new stems and leaves can grow from the side by simply plucking the stems and leaves. The main thing is that water spinach has a strong growth cycle, and loofah is also a variety that does not need to be worried.

Loofahs are relatively simple to grow. In rural areas, loofahs are generally planted by ponds, because loofahs like water and cannot be drought, and the loofahs themselves have enough water, and without enough water supply, it is difficult for loofahs to grow.

After the chrysanthemum is sown, when the seedlings are eaten chrysanthemum seedlings, when the chrysanthemum seedlings left are picked after they grow up, be careful not to pull out the roots of chrysanthemum, and directly pick the tender stems, and the roots of the chrysanthemum left behind can also grow chrysanthemum seedlings, so that you can achieve a planting multiple times picking fungus vegetables to choose a small tree to plant, grow up in spring, climb a branch, pick leaves and eat until autumn, don't care about anything, the key is that its autumn seeds fall to the ground, and the next year they will give birth to small fungus seedlings.

The first kind of green leafy vegetables is our favorite cabbage, which needs to be raised in advance, the second is cucumber, such vegetables are also very good, and they need to be raised in advance, and the third kind is beans, which are also very simple, and they should be raised in advance.

Legumes: soybeans, red beans, mung beans, green beans, mung beans, snow peas, and lentils are all very easy to germinate and have a high emergence rate. Cucumbers, winter squash, pumpkins, loofahs, zucchini, and chayote. Ordinary seedbed seedling, also known as cold bed seedling, is a traditional way of raising seedlings.

Simple vegetables to grow are rape, spinach, cabbage, lettuce, green leafy lettuce, etc.

Peat is widely used in vegetable seedlings, often used as a cultivated peat, the total porosity is 77% 84%, of which the macropores are about 5% 30%, and the water holding capacity is 50% 55%, in the seedling germination stage and seedling growth period, the EC value of the substrate should be controlled in: 2 dilution) range, carbon and nitrogen ratio is low or moderate.

Through seedling raising, the seedling period is short, no roots, and no disease. Seedling cultivation has many benefits for the growth and development of vegetables, so it is possible to grow seedlings as much as possible. Some vegetables are integrated into seedlings, and some vegetables are not suitable for seedlings, such as green leafy vegetables, broccoli, oily lettuce, chrysanthemum, small green vegetables, especially fruit vegetables, which generally like warmth and are not resistant to low temperatures, afraid of frost and frost; However, the frost period in some areas is relatively short, and some nightshade vegetables are cultivated in the open field after the frost breaking, not only the growth period should be extended, the picking period will be delayed, and the seedling bed seedling can get rid of the problem of stunted growth and development of seedlings in saline-alkali soil, which is conducive to the distribution and connection of stubble, alleviating seasonal differences, and is conducive to the completion of large-scale planting of anniversaries, thereby improving the utilization rate of land resources.

Effective use of soil resources and improve the utilization rate of land resources Because seedlings occupy a small land area, the application of production and manufacturing fields is reduced, so land resources can be saved. When the seedlings are not pulled in the field before the seedlings are raised, the seedlings can be transplanted immediately after the second stubble is pulled, which can greatly save the amount of seeds and promote the faster utilization of seeds. Reduce the probability of bad seeds, reduce the situation that the planting cannot be planted and the germination is not long.

Because of centralized seedling raising, it is convenient for management, conducive to pest control, conducive to resisting the harm of poor natural conditions in the seedling stage, and conducive to cultivating prosperous seedlings. As the saying goes, "Rich buy seeds, but no money buy seedlings."

Half of the seedlings are harvested". When selecting seeds, no matter what kind of food seeds, we should choose seeds that are a little more rounded, so that the seeds have a higher survival rate.

Before raising seedlings, put the seeds in the sun to fully expose to the sun, which is beneficial to kill the pathogenic bacteria in the whole process of storage and grafting seedlings is simpler, and it is also very commonly used by everyone, and everyone should have seen some of the grafting methods, and the grafting seedlings of vegetables are actually the buds or branches of green plants, grafted to the moderate position of another green plant.

According to the type of planting, the hole tray suitable for the hole is generally 72 holes, the melon vegetables are generally 50 holes, and the oil wheat vegetables are generally 128 holes. Clean the impurities in the hole tray and put it in the potassium permanganate solution to soak and disinfect and sterilize.

All kinds of early-maturing vegetables planted in sheds should be harvested in time; grasp the sowing of green leafy vegetables; Sowing and seedling raising of various vegetables for summer sowing. Strengthen field management and pay attention to the prevention and control of pests and diseases.

Sowing seeds and raising seedlings. The vegetables that can be sown are: cabbage, radish, amaranth, bamboo leaf cabbage, sunflower, lettuce, spinach, edamame, cowpea, lentils, etc., which can be broadcast in the open field; There are also cucumbers, cowpeas, winter melons, and eggplants that can be raised in nutrient bowls.

Field management. When planting, avoid planting vegetables suitable for growing in acidic soil in alkaline soil, and pay attention to the soil environment suitable for vegetables before planting. Most vegetables are suitable for the pH of the soil.

Sprinkle some plant ash and lime powder in acidic soil to neutralize the soil, and also increase the fertility of the soil, so that vegetables grow more vigorously.

Temperature-loving vegetables, long growth period, due to continuous harvesting, large fertilizer consumption, in addition to the application of foot fertilizer, but also to achieve timely topdressing after harvesting.

Summer-sown cucumbers, cowpeas, etc. should be set up in time.

Tomatoes should be pruned, topped, thinned flowers, and thinned fruits; Eggplant should be cut off from the old leaves to facilitate ventilation and light, and remove the eggplant as soon as possible.

Watermelon, melon, winter melon, and pumpkin should be pruned and pressed in time; When topdressing all kinds of vegetables, avoid applying rich fertilizer for jujubes; After the rainstorm, pay attention to ditch cleaning and drainage. When chemical weeding, do not overdose; Harvest in a timely manner, so as not to affect the growth and development of flowers and fruits in the future and reduce the yield.

There are also edamame, lentils, and sword beans that are managed according to local regular production requirements.

Pest and disease control.

Pay attention to the prevention and control of cabbage, Chinese cabbage soft rot, tomato early blight, gray mold, umbilical rot, bacterial wilt, eggplant brown streak, cotton blight, cucumber downy mildew, powdery mildew, anthracnose, cowpea rust, root rot, coal mildew, lettuce downy mildew, sclerotinia sclerotinia and so on; Pay attention to the prevention and control of aphids, yellow gourds, cabbage worms, diamondback moths, beet armyworms, yellow koji jumping beetles, American spotted divers, etc.

Harvest in time. Cucumbers, gourds, zucchini, loofahs, bitter gourds, pumpkins, vegetable melons, tomatoes, eggplants, peppers, kidney beans, cowpeas, edamame, peas, broad beans, potatoes, cabbage, radish, lettuce, cabbage, cauliflower, bamboo leaf vegetables, amaranth, coriander, chrysanthemum, garlic, leeks, onions and other vegetables should be harvested in time.

Direct sowing is mainly garlic, leafy vegetables, beans:

Garlic, watercress, leeks, evening lettuce, late spinach, bitter vein, spring green beans, evening lettuce, late spinach, watercress, water spinach, Jinshan beans, April beans, baby cabbage, morning cabbage, amaranth, early rasp, August beans, baby cabbage, Jinshan beans, early kale, morning cabbage, anti-pu melon, anti-bitter gourd, late loofah, bowl beans, early radish, carrots, autumn beans...

Seedlings are mainly transplanted with onions, melons, persimmons, eggplants, and peppers

Onion, green onion, pumpkin, cucumber, tomato, pepper, kale, winter melon, pumpkin, cucumber, green and red pepper, chili, June taro, August taro, white melon, spring tomato, spring eggplant melon, spring pepper, ginger, bitter gourd, August bean, autumn cucumber, autumn tomato, autumn eggplant, chives, cabbage, mustard greens, early lettuce, early Beijing cabbage, amaranth, anti-winter melon, anti-pumpkin, anti-bitter gourd, anti-pu gourd、。。

After seedling raising, the seedling period is short, no roots, no disease. Seedlings have many benefits for vegetable growth, try to plant seedlings as much as possible. Some vegetables are suitable for seedlings, and some vegetables are not suitable for seedlings, such as green leafy vegetables, spinach, rape, chrysanthemum, and oilseed vegetables, especially fruit vegetables, which are generally temperature-loving but not cold-tolerant, afraid of frost and frost; However, the frost-free period in some areas is relatively short, and some nightshade vegetables are not only prolonged during the growth period and the harvest period is delayed, but also the seedling bed can overcome the problem of slow growth of seedlings in saline-alkali land, which is convenient for stubble arrangement and docking, alleviates the seasonal contradiction, and is conducive to the realization of annual intensive planting, thereby improving the utilization rate of land.

<> rational use of land resources and improve land utilization rate due to the small land area occupied by seedlings, the use of production fields is reduced, so land can be saved. When the seedlings are not pulled in the field, the seedlings can be planted in time after the second stubble seedlings are pulled, which can greatly save the amount of seeds and make better use of the seeds. Reduce the probability of bad seeds, reduce the situation that the sowing is not produced and the seedlings do not grow.

Due to the centralized seedling raising, it is easy to manage, conducive to pest control, easy to resist the influence of unfavorable natural conditions in the seedling stage, and easy to cultivate strong seedlings. As the saying goes, "There is money to buy seeds, but there is no money to buy seedlings."

Half of the seedlings are harvested". When choosing seeds, no matter what kind of vegetable seeds, we should choose fuller seeds, so that the survival rate of seeds is high. Before raising seedlings, put the seeds in the sun and fully exposed to the sun, which is conducive to killing the germs in the storage process Grafting seedlings is simpler, and it is also more common for us, and we should have heard some of the grafting methods, the grafting seedlings of vegetables are actually the buds or branches of the plant, grafted to the appropriate part of another plant.

According to the sowing variety, choose the appropriate number of holes, nightshade and cruciferous leafy vegetables are generally 72 holes, melons are generally 50 holes, and lettuce is generally 128 holes. Clean up the debris in the hole tray and soak it in potassium permanganate solution for disinfection.

It should have the characteristics of rich organic matter, loose texture, strong fertilizer and water retention, slightly acidic or neutral, reasonable ratio of nitrogen, phosphorus and potassium, and basically eliminate the survival conditions of diseases and insects. It is best to use relatively fertile, 5 consecutive years have not been planted with eggplant fruits, melons and cruciferous vegetables field soil as bed soil, the soil quality to sandy soil is better, and pay attention to the selection of 13 17cm within the topsoil.

(1) Variety selection is based on the target market demand, combined with local natural climate, soil conditions and stubble connection, and the selection of excellent varieties.

2) The formulation of vegetable seedling plan according to the characteristics of vegetable varieties and cultivation season, determine the reasonable seedling method, seedling scale, seedling facilities, seedling substrate, etc., determine the seedling period and seedling stage temperature, humidity management, common pest control measures, etc.

Nutrient soil needs to be prepared, and there are many requirements for nutrient soil, among which the nutrients needed by the soil are nitrogen, phosphorus, potassium, calcium, etc. The most important thing is to be rich in organic matter, maintain good ventilation and the ability to retain water and fertilizer, and at the same time be slightly acidic to neutral, and the soil does not contain disease-carrying pathogens. The nutrient soil needs to be loose, but it should also have a certain stickiness, and it should not be loose when transplanting.

Seedbed laying and use of fertilizer. The seedbed is neatly raised, and plantar fertilizer (organic fertilizer) is applied. Do not use chemical fertilizers.

Management of the nursery and growth period of greenhouses. Temperature, humidity, light and the use of fertilizer and water. According to the local acquisition, and market sales, investigate what are the best-selling varieties in your area.

Because you said that you want to contract 40 acres of land, you will not simply plant only one, but match the varieties and planting quantities according to market demand.

<> summer cultivation is to artificially create an environment suitable for the growth of vegetables in summer, and use shading and cooling to make vegetables grow safely over summer. Summer growth of vegetables such as tomatoes, leeks, celery, etc. Improve the scientific and technological content.

For example, shed cultivation uses non-drip longevity film, two-layer warm film, reflective curtain, shade net, insect-proof net, drip irrigation, infiltration irrigation, application of biological fertilizer, carbon dioxide fertilizer, bee pollination, etc., to increase the scientific and technological content in the production of vegetables is a very busy way, the garden is to be busy in the field every day, even if it rains to the field. Playing harvesting, don't go to the old vegetables, melons and fruits, beans, especially the bean crops are old, who wants them.

In winter, off-season vegetable production should choose cold-resistant, disease-resistant, and early-maturing varieties, and varieties after autumn delay also require heat tolerance at the seedling stage. For example, pepper has updated No. 4, updated No. 5, Xiangyan No. 9 pepper, Xiangyan No. 10 pepper, Xiangyan No. 11 pepper, seeds are very important, good seeds are half the success, water and fertilizer management, pest control are all need to pay attention to many aspects. You don't know the conditions of the land and the habits of using fertilizer, so it is best to plough the soil when planting, and pay attention to providing it with the right amount of light so that it can grow and thrive.

Vegetables such as yam and eggplant have a large demand for light and need to receive strong light to meet their growth needs; while cabbage and broccoli only need to be maintained in semi-shade; Mushroom vegetables should be less light.

Three-dimensional planting can make rational use of time, space and soil nutrients, and improve the multiple cropping index. For example, spring cucumbers are intercropped with oyster mushrooms, summer beans are intercropped with straw mushrooms, watermelons are interplanted with bell peppers, long loofahs, chayotes, pumpkins are planted on the scaffolds, and coriander is planted under the shed.
