Does planting shallots next to tomatoes and cucumbers prevent insects?

If you choose onions and green onions for planting, stubble is also good. If it is planted with cucumbers, tomatoes, eggplants, etc., the effect of stubble will be better. Green onion planting base at present through the way of stubble planting vegetables, has become a variety of internal environment improvement and soil improvement is a very good method, not only the planting technology is stable, the planting effect is very good, and in ensuring that no pesticides are used, effectively achieve the effect of preventing pests and fungi, have a very obvious role.

In the practice of centralized management of agricultural vegetable planting, it is necessary to choose a variety of roles that have mutual constraints in order to determine the conditions for ultimately achieving higher yields and safer and healthier guarantees, and the promotion of green and environmentally friendly planting technology is a very important task and condition. As the most popular vegetable, green onions ensure the clear requirements and effects of safe planting, the selection of planting technology and varieties is the foundation, and the method of insect control and insect pests is also a very good choice. From various professional bases to small vegetable gardens of farmers, it is a very good way to use the method of stubble planting to prevent insects and low pesticide hazards.

In the practice of green onion planting, in addition to this way of stubble can effectively achieve the role of preventing insect pests, there is also a multi-purpose planting technology, which will also improve the yield and slow down the damage of insect pests, which plays a good role, that is, often cultivating soil. First of all, the soil is constantly cultivated in the growth, increasing the length of the green onion, improving the yield and the use rate of green onions are very good, and the other is to turn the soil frequently, which also has a very good effect on improving the yield.

Planting green onions next to tomatoes and cucumbers is not insect proof, because green onions do not have an insect repellent effect, and green onions can also be harmed by insects.

Tomatoes are planted with calendula, borage, petunia and dill to protect against insects. 1. Dill (dill): attracts a variety of beneficial insects such as aphid flies and parasitic wasps.

Repels aphids, spider mites, pumpkins and elephants. Attracts tomato moths and their larvae, so they can share the worries of tomatoes. A good companion for alliums, kale, corn and cucumbers.

Promotes the growth and health of kale. But don't grow it with carrot vegetables and caraway seeds. 2. Calendula (Pot Marigold):

Exterminates tomato moths and their larvae, asparagus beetles and other pests. It is a good partner for tomatoes and asparagus. 3. Borage:

Attracts bees and parasitic wasps. Expelled tomato moth and its larvae, cabbage worm. It can enhance the disease resistance of almost all vegetables.

It is a good partner for melons, tomatoes, and strawberries. Promote the growth of tomatoes and enhance disease resistance. Increase strawberry yield and flavor.

The leaves contain calcium, potassium and a variety of trace elements, making them a good mulch. 4. Petunia: Exterminates asparagus beetles, leafhoppers, aphids, tomato moths and their larvae, bean beetles and other pests.

The leaves can be made into tea as insect repellent. It is a good partner for asparagus, beans, and tomatoes.

The tomatoes and cucumbers of the green onion species are not insect proof, I have not heard that the green onion can also prevent insects, the green onion does not have this function, but the green onion is relatively easy to dry.

Put the green onion seeds. Knife tomatoes and cucumbers next to insect control this I really haven't heard of, I haven't heard of planting green onions next to tomatoes can also prevent insects. Then maybe you test it, and see if there is such a statement, it proves that someone may have experimented like this, maybe one thing drops one thing, and maybe the smell of the rush is against the bugs.

It's defensive, and it's true that this can't be prepared. So you can do some experiments. If it's good, then maybe this method is correct, if it doesn't work, wait for the New Year, then we won't plant it, it's nothing.

Cucumber, (Cucumis sativus linn, Cucumber), cucumber in the family Cucurbitaceae. Also known as courgette, cucumber. The fruit is oily green or emerald green in color, with small soft thorns on the surface.

It is widely cultivated throughout China and is now widely cultivated in temperate and tropical regions. Cucumbers like warmth and are not tolerant to cold, and are one of the main greenhouse products. petioles slightly rough, with rough bristles, 10-16 (-20) cm long; Leaves broadly ovate-heart-shaped, membranous, 7-20 cm long and wide, very rough on both sides, covered with coarse bristles, 3-5 angular or shallowly lobed, lobes triangular, toothed, sometimes marginal hairs at the margins, apex acute or acute, base bent semicircular, 2-3 cm wide, cm deep, sometimes the base is close to the back.

Monoecious. Green onions, scientific name: allium fistulosum giganteum makion), is a type of green onion, which can be divided into four types: ordinary green onion, divided green onion, green onion, and floor onion. The green onion has a pungent taste, slightly warm in nature, and has the effect of publishing Tongyang, detoxifying and flavoring, sweating, antibacterial and vasodilation.

It is mainly used for symptoms such as wind chill and cold, chill and fever, headache and nasal congestion, cold and abdominal pain, dysentery and diarrhea, internal obstruction of insect accumulation, milk blockage, and unfavorable stool. Green onions contain volatile oil, the main component of the oil is allicin, and it also contains diene inner sulfide and calcium oxalate. In addition, it contains fat, sugar, carotene, vitamin B, vitamin C, niacin, calcium, magnesium, iron and other ingredients.

It is a perennial herbaceous plant with cylindrical leaves, hollow in the middle, fragile and easy to break, and is blue. In East Asian countries and various Chinese areas, green onions are often eaten as a very common spice condiment or vegetable, and play an important role in oriental cuisine. In Shandong, there is a way to eat green onion dipping sauce.

Open field cucumbers. 1. Variety selection.

Varieties with high yield, strong disease resistance, good commerciality, and suitable for cultivation in spring dew should be selected.

2. Seedlings. The seedling age is about 35 days, and the standard of strong seedlings: the cotyledons are intact, with 3-5 true leaves, the internodes are short, the angle between the petiole and the main vine is 45 degrees, the leaf color is dark green, the leaves are thick, the stem is thick, the root system is developed, and there are no diseases and pests.

3. Fertilize and make furrows.

5 cubic meters of organic fertilizer for land preparation, fertilization and decomposition, 25-30 kg of superphosphate or 10-15 kg of diammonium phosphate (5-5 kg of superphosphate per cubic meter, 2-3 kg of diammonium phosphate per cubic meter). Before planting, plough the furrow, the width of the furrow is more than 15 cm, and it is covered with mulch.

4. Colonization. 1) Determination of the colonization period.

On the premise of ensuring that there is no freezing after planting, planting is generally carried out in the Chengde area in late April and early May. Temperature index requirements: the minimum night temperature is higher than 5, and the soil temperature is higher than 12 at 0-10 cm. The cucumber in the autumn dew field adopts the method of live broadcasting.

2) Colonization density.

4000 4500 acres of plants, planted in large and small rows, 40 cm in small rows, 80 cm in large rows, 25-30 cm in plant spacing, planted with dark water.

3) Field management.

a. Socket frame. After planting, the shelf should be planted as soon as possible, and the seedling should be drawn by wind, and the shelf can be a flower stand or a herringbone frame, about 8-10 cm away from the root.

b. Tie vines. The "8" method is used to tie vines to prevent abrasion of stems and vines and sagging stems. Tied once every 2 3 sections, should be carried out in the afternoon, the stem vine is easy to break in the morning, the tightness of the vine should be suppressed and the weak should be strengthened, and the growth of the plant should be tied tightly, and the height of the growth point is consistent.

c. Pruning and pinching. For the main vine, all the side branches should be removed, and one or two leaves should be left after the side vine is fruitful, and all the tendrils should be removed. When the stem exceeds the head of the shelf, it is necessary to pinch the tip in time to promote the growth of the lower melon, and the method of twisting the tip can also be used to inhibit the growth of the upper part.

d. Fertilizer and water management. Timely watering and cultivating, the amount and frequency of water depends on the weather and growth period. Slow seedling water is watered 5 to 7 days after planting; water control, cultivating, and squatting seedlings before sitting on melons; When the root melon is 10 12 cm long, water the melon; Watering during the fruiting period is watered every 5-7 days.

The principle of top dressing is that the front is light and heavy, a small amount of many times, urging melon fertilizer to be applied after the root melon sits, and the melon fertilizer is carried out after the root melon is harvested. Promote the use of organic fertilizer topdressing.
