Cultivation techniques of garlic seedlings

Garlic sprouts, also known as green garlic (garlic yellow when there is no light). The garlic seedlings with good quality should be fresh and tender, the plant height is about 35 cm, the leaves are bright green, neither yellow nor rotten, the hairy roots do not wither, and the spicy taste is strong. Garlic seedlings have a certain protective effect on cardio-cerebrovascular, can prevent the formation of thrombus, but also protect the liver. Can grow everywhere, and the output is high and the quality is good. Such as Shandong Linyi and other places large-scale planting, the economic benefit is considerable. Next, let's introduce the cultivation techniques of garlic seedlings.

I. Scientific planting

After ploughing the land and opening the "three ditches", it is necessary to apply sufficient base fertilizer at one time. The base fertilizer is generally 100 kilograms of rotten soil residue manure, 20 kilograms of urea, 50 kilograms of phosphate fertilizer, 15 kilograms of potash fertilizer or 50 kilograms of high-quality three-element compound fertilizer. Under the condition of sufficient base fertilizer, the seeds can be sown from early August to early September, or from late September to late October. Autumn garlic seedlings in the early growth period is in high temperature weather, can build a 1-meter-high flat shed, covered on the shed.

2. Cultivation techniques of out-of-season garlic seedlings

Garlic seedlings are routinely sown in autumn and harvested in winter and spring. In order to improve the economic benefit, the off-season cultivation method of sowing in late July and harvesting period from September to October can be adopted. The growth of garlic in this season is in a period of high temperature and strong light, which is easily affected by adverse weather such as high temperature, drought and strong solar light. the following techniques must be adopted:

1. Variety selection

It is easy to choose precocious varieties with high temperature resistance, good performance and high yield. Sichuan hard-leaf garlic variety "Ershuizao" or soft-leaf garlic, due to the mixed nature of garlic, vegetable farmers must go to the regular unit to buy and grow.

two。 Fine soil preparation and application of sufficient base fertilizer

Due to the short growth period of summer sowing garlic, it is necessary to increase the density and increase the yield, so it is necessary to apply sufficient base fertilizer, 3500 kg of high-quality rotten barnyard manure and 30 kg of superphosphate per mu, and it is appropriate to choose sandy loam soil. The soil was turned over a week before sowing, and then fertilized and sowed.

4. Sowing and raising seedlings

Summer sowing garlic because of high temperature, short growth period, short plants, can increase the density and yield, generally use about 200 kg of garlic per mu, planting according to the row spacing of 10-12 cm, plant spacing 3-5 cm sowing, sowing, sowing first sufficient bottom water, sowing after sowing, just cover the soil, after sowing, cover 3 cm thick rice straw on the border surface to cool down, watering should be carried out before 9 o'clock in the morning.

5. Field management

Set up a 30cm scaffolding on the border, cover the sunshade net or grass curtain to shade the sun, complete the seedlings and remove the shade shed. After the first topdressing of garlic seedlings, urea or rare human and animal manure can be used to irrigate garlic. In short, we should grasp the principle of frequent watering of thin fertilizer, and fertilize every time we harvest.

6. Harvest

About 50 days after sowing, fresh and tender garlic seedlings can be harvested and put on the market in batches. in order to prolong the supply period and increase the yield, separate harvesting should be used to list in batches.

Third, reasonable close planting

The practice of ditching and sowing, generally row spacing 10 MUE 15 cm, plant spacing 3 MUE 5 cm, mu with 150 MUE 200 kg garlic. When planting, you can scatter the garlic cloves into the hoe trench, use both hands according to the spacing, and cover the soil with your hands while sowing to prevent the garlic cloves from tilting. Water thoroughly immediately after sowing, and cover the soil once after watering. 3After 4 days, water was poured twice and 20 kg of ammonium sulfate was fertilized with water. After fertilization, water was watered every two days for 3 times in a row. Cover the soil for the second time when the seedling is 20 cm high. At the same time, pay attention to spraying to control diseases and insect pests after emergence.

Fourth, how to plant garlic seedlings on the balcony

1. Garlic seedlings are very common green leafy vegetables. They all talk about pure organic pollution-free vegetables, but garlic seedlings bought outside will sometimes buy garlic seedlings sprayed with pesticides. What should I do? In fact, we can grow on our own balcony, garlic seedlings grow out, as long as the roots are still there, it will grow infinitely, let's talk about how to plant garlic seedlings on our own balcony.

two。 Find a needle and thread, thread it, and peel off the garlic (you can't peel it with the usual violent flattening method here! It will destroy the organization.) put the garlic into a string.

3. Just put it in a container and culture it with water (the above is the record of each day's rise) the water is cloudy.

The water should be changed in time in the future. Since garlic seedlings can grow indefinitely, they can be picked every two days, and a large plate of vegetables can be made each time.

4. When wearing garlic, it is best to wear it on the outer layer so as not to damage the germ tissue inside. The garlic is worn in a string to keep the garlic from floating around in the water. Thread when wearing two layers, can better play a fixed role to prevent garlic seedlings from growing askew.

5. Fertilization technology

1. Base fertilizer

When producing garlic seedlings in a greenhouse or greenhouse, plant the garlic directly to the ground.

Before planting, apply 150000 kg of fine and fine farm manure per hectare, spread it on the ground, turn 20-25 cm deep, mix the fertile soil well, rake flat to make the bed.

two。 Topdressing

Garlic seedlings are cultivated in the greenhouse, and when applying sufficient basic fertilizer, there is generally no need for topdressing. However, if the lack of nitrogen fertilizer affects growth, ammonium phosphate can be dissolved in water for pouring, topdressing 225,300kg per hectare. Chemical fertilizer should not be sprinkled directly before watering. In order to promote the rapid growth of garlic seedlings, 200 times ammonium nitrate fertilizer solution can be used to irrigate once when the seedling height is 20 cm, ammonium nitrate 75-90 kg per hectare; potassium dihydrogen phosphate, high yield element, urea and so on can also be used for foliar topdressing, each time after foliar topdressing, water should be sprayed on both sides to avoid fertilizer damage.
