Is there really a vegetable that doesn t need to be sprayed? In what season should it be planted?

In rural areas, almost all farmers have the need to directly plant vegetables, but no matter what vegetables are planted, in the planting process, they will encounter various pests and diseases, especially in the current season, the temperature is rising, and the pest and disease problems in the vegetable fields are becoming more and more serious, affecting the normal growth of vegetables, resulting in farmers to spend money and time and energy, to spray, remove insects, etc., and the production efficiency is not high! It's not healthy, it's not environmentally friendly! The agricultural know-it-all is here to recommend two kinds of high-quality vegetable seeds that can be sown in the field and planted directly without pesticides for the majority of farmers!

I must first introduce lettuce vegetables, which have very few pests and diseases, and they grow beautifully. The lettuce vegetables we commonly grow include lettuce, lettuce, lettuce, and peacock vegetables that have been newly cultivated in recent years. In the northern region, spring and autumn stubble can be planted, and the sowing is completed around the spring equinox, and the seeds are sown after the beginning of autumn in autumn.

Leafy greens.

There are many green leafy vegetables that almost do not need pesticides during the growth period, such as celery, leeks, chrysanthemum, coriander, etc., whether these vegetables are planted in greenhouses or in their own yards, as long as they are managed in place, they almost do not need pesticides. This is because these vegetables have a relatively short growth period, and they are ready to be harvested before the insects hatch, and then these vegetables have a common feature, that is, they have a special fragrance, which is the main reason why these vegetables are not easy to produce insects.

Leek. Leeks have a strong ability to regenerate, and they can be harvested many times when planted once, so they are affectionately called "lazy vegetables" by farmers. In rural areas, people like to plant some leeks in their yards, in addition to the reason that leeks can be harvested many times, leeks can be grown almost without pesticides during the growth period has also become the main reason why people choose to plant it.

Leeks have a very special smell, so insect pests rarely occur during the growth period, and the easy insect pests are underground pests, as long as they are sprinkled with some plant ash from time to time, they can be eliminated.

In general, these two vegetables are sweet and crisp and tender high-yield varieties, at the same time, this vegetable also has the advantages of no insects in summer without pesticides, planting such vegetables can be said to be time-saving and labor-saving, green and environmentally friendly, very recommended, in the countryside there are vacant land to plant some vegetables of farmers friends, you can start!

Beans, eggplant, peppers, bell peppers, cabbage, radish, tomatoes, spinach, cucumbers, rape, lettuce, potatoes, lettuce, etc., these can be sprayed almost without pesticides.

It should be planted in winter because: there are fewer insects in winter, you can not spray pesticides, and most pesticides are used to prevent insects.

I think there are vegetables that don't need to be sprayed. I think it was planted in the spring, because the spring flowers bloomed, everything recovered, and all the plants began to thrive.

Only the vegetables you grow are not sprayed, and the other vegetables you buy must have spraying, and now many people buy vegetables to see the appearance of the vegetables, if there are insects or insect eyes, they will not want it, so spraying must be very normal, you should plant vegetables in the spring, and you can eat them in the summer.

I think there are fewer such vegetables, maybe more in the spring, like some greens or cabbage.

Of course. It should be planted in the spring, and planting in the spring can also promote growth to a certain extent, and the environment and temperature are more suitable.

Yes It should be planted in the winter because there are very few insect infestations in the winter and it grows very well.

For example, you can also use sweet potatoes, potatoes, hemp yams, red and white radish, coriander, celery, tomatoes, moss, pumpkin, pumpkin, winter melon, loofah, and other melons, onions, ginger, toon, mushrooms, taro, etc. There are also cereals, sorghum, sesame seeds, beans, etc. Corn spring planting without pesticides, is not good at all, do not like to plant, and so the corn matures every day there are a few corn for the squirrel to eat, once the squirrel has eaten the land, can be eaten in a row, planted twice corn are like this, the third time do not need to plant.

<>However, in the past, sweet potato planting almost did not use pesticides, and farmers were only responsible for hoeing, but now sweet potatoes have also begun to use pesticides, metaphors: in order to prevent grass from growing in sweet potato fields, herbicides on closed ground, etc. My father-in-law has a small vegetable garden at home, and he grows vegetables according to the different seasons, and uses farm fertilizer, and rarely uses chemical fertilizers and pesticides, so although the yield of the vegetables he grows is not high, his own family can't eat them.

Sesame, sesame is a kind of straw crops, rhizomes and leaves have a strange taste, itself does not attract insects, when the seedlings are small, there is a pest called "slippery bugs", easy to gnaw its roots, other underground pests, see sesame are respectful. It's hard to think of high-quality crops that can be grown without pesticides at all. Unless you can create a new way to isolate yourself from soil, which is the basic medium of agricultural production.

Otherwise, it would be almost impossible to achieve this in traditional agricultural production.

Potatoes, carrots, eggplants, tomatoes, bok choy, rape, lettuce, radishes, cloud beans, radishes, and almost all vegetables grown by farmers are not pesticides. Because it is a small greenhouse, insects can also adapt to the temperature can violate the vegetables, but some vegetables can not grow at high temperatures, but insects still have to produce illegal crops in late autumn, inevitably greenhouses and open fields are two things, I said these vegetables in the local open air to adapt to grow. Leeks, carrots, etc. do not need to be sprayed with pesticides, and occasionally there are insects that can be caught manually, after all, the number of planted is relatively small and can be seen; If the area is large, you can't take care of it, so you can only spray pesticides, but you should pay attention to the interval and eat it when the effect is gone.

Coriander; Coriander, also known as coriander, is one of the common condiment vegetables in our lives, which can be planted in all seasons, and is often sown in the open field before and after Qingming; Because coriander has a strong aroma, it is deeply loved by people; The reason why coriander can exude a rich aroma is because the stems and leaves of coriander can release a substance of aromatic volatile oil, which can increase the taste of dishes and make them more delicious and attractive; The volatile oil of coriander in the plant can protect the cells and tissues of coriander from being infected by fungi and microorganisms, and the aromatic odor emitted by the volatile oil of coriander can drive away insect pests. Therefore, during the planting cycle, there is basically no pest and disease nuisance, and there is no need to spray any pesticides.

Capsule, Radix Root, Grey Striped Cabbage, Bracken, Toon, Begonia Pear Flower, Gorse. These vegetables are generally grown without the use of pesticides. Vegetables that are not grown with pesticides are not relatively safe, but they are relatively greener and more natural.

For example, water spinach, spring cabbage, kale, cabbage, and leeks can be used without pesticides, but it does not mean that vegetables without pesticides are absolutely safe, and it can only be said that they are more green and environmentally friendly than medicated vegetables.

1. Aphids, red spiders, whiteflies, these pests mainly harm the young leaves of vegetables, mainly the folic acid in the young leaves, they prefer to eat these, but the impact of the vegetables is relatively large, this can be used to mash the leeks, take the juice, add 100 neutral laundry detergent, mix with a bucket of water, and spray, because the juice of the leeks will not change the taste of the young leaves, and there is a tendency to avoid, the juice can be stuck by the washing powder, increasing the validity period.

2. Diamondback moth, cotton bollworm, cabbage worm and other insect pests, many growers respond that pesticides do not work after spraying, and they are also very painful, because of the long-term use of pesticides, pests have resistance, so the effect of spraying is not ideal.

3. If there is a situation that can not be prevented by spraying, you can use zombie insect control, you can find a seedling with more insects at night, put a plastic bag on the ground, start to card the seedlings, let the insects fall on the plastic bag, collect about 200 grams, mash it, spray it with a bucket of water, treat the insects with insects, and the insects can be prevented from returning to the shirt.

Some of the vegetables planted by farmers in summer do not use pesticides, and they are healthy and delicious to eat, such as coriander, lettuce, sweet potato leaves, fungus, etc., the reason why these vegetables do not need to use pesticides when planting is because it is rainy and thunder and lightning in summer, which belongs to natural fertilization, and the growth of these vegetables is also more gratifying.

Coriander does not need pesticides when it is grown in the summer, because coriander likes a hot and rainy environment, and summer is just the right place for this. Coriander has a strong flavor, many people may not be able to smell this taste, and even some small insects dare not approach coriander, so naturally there will be no problems such as insect eyes. In summer, coriander has a higher germination rate after rain, and it is very large, grows well, and tastes delicious, and it is also a common vegetable on the summer table.

Lettuce in summer can be eaten directly raw, many people can put a piece of it in the morning when eating egg cakes or finger cakes, not only the taste is sweet and refreshing, the nutritional value is also very high, lettuce as another category of green vegetables, the growth rate is very fast, and it is not easy to grow insects in the process of growth, especially in summer, there is no need to spray pesticides, you can grow directly and quickly. Lettuce itself has a special smell, which is generally disliked by small insects, so lettuce rarely has insect eyes, and in summer, coupled with a rainy environment, it grows more vigorously.

Sweet potato leaves, a vegetable that is usually eaten by people and used to feed pigs or chickens, are grown in rural households. It is true that sweet potato leaves do not need to be sprayed with pesticides during the planting process, although they may be harmed by earthworms during the planting process, but as long as the water and fertilizer are suitable in summer, the yield will not be very low. In recent years, people in the city have also had a good impression of sweet potato leaves, because it is very low in calories, the best food, and there is no spraying of pesticides, so it is naturally better to sell.

Fungus is also one of the common vegetables on the summer table, in the process of planting, the vitality of the fungus is very tenacious, the leaves are very fat, and the taste is crisp and sticky. It is perfect for making soup or stir-frying. There are almost no pests and diseases when planting, and it is also because the fungus contains a special smell that insects do not like.

The nutritional value of fungus vegetables is very high, although some people are not very acceptable to eat, but it is undeniable that the characteristics of low calorie and high nutrition still make fungus vegetables unique in a kind of vegetables and are loved by many people. In addition, fungus can also be grown as an ornamental plant, and the leaves are large and green in the yard or on the balcony, which is very beautiful, and is not inferior to succulents.

All in all, these vegetables do not need to be sprayed with pesticides in the process of planting in summer, mainly because these vegetables themselves contain a special fragrance in the night scene, which does not attract insects, so that their leaves can be preserved, and there will be no recurrence on them, and naturally there is no need to spray too many pesticides. Therefore, in summer, we can choose these vegetables to eat as seasonal vegetables, which can bring a different taste enjoyment and be more green and healthy.

In the summer, farmers will grow some vegetables that do not use pesticides, such as coriander, lettuce, sweet potato leaves, fungus, etc., these vegetables are not pesticides, because it often rains in the summer, and there are often lightning, so these vegetables will grow quickly.

pumpkin, winter squash, loofah, coriander, green onion, sweet potato, ginger, garlic; These vegetables emit a strong smell during their growth and are not easy to attract insects, so they can be used without pesticides.

For example, there are cabbage, celery and mustard greens, as well as wheat vegetables and wasp greens, and they do not use pesticides, because these vegetables are theoretically wild vegetables.

Lettuce. This is lettuce, which is a vegetable that can be eaten as is.

Sweet potato leaves. Sweet potato leaves do not need to be sprayed with pesticides during the planting process. However, during the planting process, it will be harmed by earthworms and other disasters, but as long as the water and fertilizer are properly managed, the yield will not be too low.

Lettuce does not need to be sprayed with pesticides, and there are not many insects growing in the growth process, so there is generally no need to spray pesticides. This is a vegetable that can be eaten raw as is. Like many people who like to eat egg scones and finger cakes for breakfast, they will put lettuce.

And it's really delicious, refreshing, and highly nutritious. Sweet potato leaves sweet potato, and it really doesn't need to be sprayed with pesticides during the planting process. Although this crop will be damaged by earthworms and other disasters during the cultivation process, as long as the water and fertilizer are properly managed, the yield will not be too low.

In recent years, it has become a very popular vegetable, and is also known as the "queen of vegetables". Since sweet potatoes do not need to be sprayed with pesticides, there is no need for natural sweet potato leaves.
