How is garlic grown? How is the garlic grown?

How do you grow one-headed garlic from common garlic? It's a simple and easy way to grow garlic.

The formation of one-headed garlic requires a special environment to form.

For garlic, the proportion of garlic that can be formed into a single head of garlic is generally about 5-10. The formation of these one-headed garlic requires a special environment to form, such as too late sowing period, early maturing varieties, poor soil, insufficient water and fertilizer application, insufficient light and temperature, serious diseases, insects and weeds, too large planting density, too little branch and leaf quantity, and too small garlic cloves for sowing.

These factors lead to the lack of nutrients in garlic at the seedling stage, the inhibition of plant growth, and the sluggish differentiation of bulbs, and it is easy to form undivided one-headed garlic in the later stage.

One-headed garlicSelection and treatment of garlic species:

The probability of different varieties of garlic appearing in a single head is not the same, so when we choose garlic species, we must first consider the variety. Variety comparison trials should be carried out before large-scale production of single-headed garlic. Generally, early-maturing varieties are higher than medium- and late-maturing varieties.

Garlic varieties that are resistant to barrenness and have relatively strict requirements for squamorous bud differentiation are prone to single-headed garlic. The single-head rate of early-maturing garlic varieties such as Ershui Zao, Pengxian Early Maturity, Wenjiang Red Qixing and so on can reach 76% to 92%.

Use small garlic cloves as the garlic species. Smaller garlic cloves contain fewer nutrients, resulting in thin plants with poorly differentiated flower buds and easy to form one-headed garlic. If the garlic species is greater than 2 grams, there is a surplus of nutrients, and the garlic is easy to split; If it is less than a gram, the garlic produced is too small and has no economic value.

So it's best to use grams of small cloves of garlic.

The specific operation of the single garlic planting method is as follows:

Tools: seeds, soil, water, fertilizer, etc.

1. Determine the planting time. The spring sowing was cultivated in small arch shed, which was higher than that of mulching and open field cultivation, and the rate of spring sowing was higher than that of autumn sowing, but the yield of single garlic was lower than that of autumn. In the Yangtze River basin and areas south of it, sowing is generally in mid to late November.

2. Choose a single garlic variety. Generally, early-maturing varieties are higher than medium- and late-maturing varieties, and garlic varieties with relatively strict requirements for barrenness and squamous bud differentiation are prone to single-headed garlic. The single-head rate of early-maturing garlic varieties such as Ershui Zao, Pengxian Early Maturity, Wenjiang Red Qixing and so on can reach 76% to 92%.

3. Do a good job of garlic treatment. Before sowing, it is best to treat the garlic seeds at low temperature, and put the garlic seeds at a low temperature of 2-5 degrees Celsius for about 2 months, and the rate of single garlic can reach 50. The processed garlic seeds should be spread out in a cool and ventilated place to dissipate heat, and turned every day.

4. Determine the sowing method. In order to increase the single-head rate, the planting density should be larger. According to the distance of 15 centimeters, the ditch depth is 6 centimeters. The plant spacing is 3 cm, according to the garlic belly and back to the cutting, put the garlic seed and cover the soil thickness of 3 cm, and then rake the flat furrow surface, irrigate water, and reduce the appearance of cloves of garlic.

5. Do a good job in field management. In the process of maintaining garlic, it is necessary to apply the corresponding fertilizer according to the growth stage of the plant, generally focus on nitrogen fertilizer in the early stage of growth, and tend to phosphorus and potassium fertilizer in the later stage, pay attention to the application of seedling fertilizer and head fertilizer, in addition, when the garlic seedlings are ten to twenty centimeters high, they need to be combined with watering for weeding to prevent soil compaction, which is not conducive to plant growth.

The specific process of planting one-headed garlic is as follows:

1. Land selection and land preparation

Sand soil or sandy loam soil should be selected in the cultivation of single garlic. After harvesting, the field should be cleaned as soon as possible, and the soil should be cooked by deep ploughing. Then 2000 kg of well-decomposed high-quality organic fertilizer, 50 kg of superphosphate and 10 kg of potassium sulfate were applied per mu.

Fine land preparation, with 1 meter of moisture, so that the fertilizer is evenly furrowed and the soil is fine, and the seeds can be sown.

2. Sowing: 1) Selection of garlic: choose the main varieties of red seven stars and Ershuizao varieties, which are easy to produce single garlic under specific cultivation measures.

At the same time, try to choose a smaller seed petal with a single clove weight of 1 2g, and the single garlic rate can reach about 40%. Under high temperature and long sun conditions, the terminal bud rapidly expands and stores water and nutrients, forming one-headed garlic.

2) Seed treatment: The selected seed petals are placed in 2 to 5 low-temperature cold storage for 50 to 60 days, and the proportion of single garlic can reach 50% after cultivation. The garlic seeds treated at low temperature have been released from dormancy and germinated, and the life activities have been gradually strengthened.

After leaving the cold storage, the respiration is vigorous, and a strong respiratory heat will be generated.

After the garlic seeds are transported to the home, they should be poured out of the letter packaging bag in time and spread out in a cool and ventilated place to dissipate the heat to avoid burning the seeds. Then seize the time to sow seeds gradingly. If it cannot be sown in time, it should be turned daily.

Once or twice, make it dissipate heat smoothly. If the seed petals have grown roots and sprouts, pay attention to moisturizing and protecting the roots.

3) Sowing period: After low temperature treatment, the garlic seeds are sown at low temperature, and there is a considerable rate of garlic in early sowing, but due to the high temperature after sowing, the seedlings are very easy to senescence and fall seedlings in advance, and the single garlic formed is small in size and poor in shape (farmers call it "grass fruit garlic"). Especially in low-heat valleys, it is more prominent.

On the contrary, sowing and eliminating Tan Yu is late, the proportion of single garlic is very high, such as in the beginning of the winter season sowing test, the rate of single garlic is as high, but the yield is very low, and the small single garlic is only about 3 grams heavy. Sowing between the autumn equinox and the cold dew, the rate of single garlic is 40% 50%, the single garlic is large and of high quality, and the comprehensive output value is high, so the best sowing period for the cultivation of single garlic should be mastered in this period.

3. Field management:

1) Fertilization management: Garlic needs different types of fertilizer sources in different growth periods. In general, the early stage of growth focuses on nitrogen fertilizers, and the later stage tends to focus on phosphorus and potassium fertilizers. On the basis of applying plantar fertilizer, it is necessary to carry out appropriate topdressing.

2) Weed control: First, before sowing buds, spray with 60% butachlor 50g + 25% green melon 250g plus 50kg of water per mu; Second, when the garlic seedlings are 10 20cm high, they can be cultivated and weeded manually, and at the same time, they also play a role in loosening the soil, preventing soil compaction, and promoting root growth.

3) Soil moisture management: Garlic grows to 4-5 months, and the garlic head has expanded. Do not irrigate too much to avoid causing garlic cloves to disperse and reduce the rate of garlic alone, which will affect the quality of garlic.

1. Sowing technology of one-headed garlic.

Garlic sowing technique.

When sowing, the ditch is first opened according to the row spacing of 15 cm, and the depth of the ditch is about 6 cm, and then the sown petals are sown according to the plant spacing of 3 4 cm, and then the soil is covered with a thickness of 3 4 cm. After the whole furrow is sown, evenly sow the small radish seeds, with about one kilogram of seeds per mu, rake the flat furrow surface after sowing, and irrigate.

The purpose of mixing radish seeds is to utilize small radish. The characteristics of fast germination and seedling emergence inhibit the growth of garlic seedlings, so as to increase the single-head rate and reduce the clove of garlic.

2. How to choose garlic for one-headed garlic planting.

How to choose a single garlic planting.

The seed cloves used in the production of single-headed garlic must be small garlic cloves, so it is generally selected from garlic varieties with more garlic cloves and smaller garlic cloves. However, when the same garlic clove is small but the garlic variety is different, there is a significant difference in the percentage and weight of the single head of the obtained garlic, which affects the yield and quality of the single garlic.

Therefore, before engaging in the production of garlic, a variety comparison test should be carried out to select the varieties suitable for local planting, with a higher single-head rate and a larger single-head weight.

3. How to choose the seed cloves for single-headed garlic planting.

One-headed garlicThe size of the seed cloves for the production of garlic is related to the yield and quality of garlic. Only by choosing a suitable size garlic clove for planting garlic can you obtain a high single-head rate and a medium-sized single-head garlic.

If the seed cloves are too large, small garlic heads with 2-3 garlic cloves will be produced, which will reduce the single-head rate; If the seed petals are too small, the resulting garlic is too small and loses its commercial value. Generally, the single weight of one-headed garlic is required to reach 5-8 grams.

In order to produce garlic with a high single-head rate and suitable size, it is necessary to conduct experiments on the relationship between the size of the seed petals, the single-head rate and the weight of the single head. According to the production experience of Hubei, when using the small garlic cloves (also known as "wolf tooth garlic") in the local white-skinned garlic varieties as seed cloves, it is advisable to weigh less than 90 grams of 100 grains.

Fourth, the field management technology of one-headed garlic.

After the emergence of small radish seedlings, divide the seedlings into periods, so that keep a distance of 6 to 8 cm. In the early spring of the following year, after all the radishes were harvested and marketed, the garlic fields were managed by cultivating, weeding, top dressing, and irrigation. During the garlic swelling period, ensure sufficient moisture**.

After the harvest of the previous crop, 250 kg of rotting circle fertilizer and 50 kg of superphosphate were applied per mu as base fertilizer. After shallow tillage and rakeing, it is made into a flat furrow about a width of about a meter.
