Garlic production to achieve better cultivation benefits in addition to obtaining higher yields, but also need to obtain a higher quality, in the sales process, the head of the garlic grade is higher, the price is also higher, so in the process of production, so that the nutrients of the garlic head to fully accumulate and obtain a larger head of garlic is an important goal of garlic cultivation, to do this needs to be To do the following four aspects:
Select a good cultivation field
Select three years have not cultivated onion and garlic vegetables and the soil is loose and fertile, good drainage and irrigation of the plot of land for cultivation. Planting onion and garlic vegetables and then planting garlic, often because of the heavy crop obstacles and make the garlic disease, insect pests are more serious, is not conducive to the healthy growth of garlic is also not conducive to the growth of larger garlic head.
Garlic root system for the string-like fibrous roots, and the root system is more dense, in the growth process of the soil permeability requirements are higher, so in the cultivation process should choose the soil structure is loose and permeability of the loam or sandy loam is appropriate, sticky soil permeability is poor and compact soil, not only is not conducive to the growth of the root system and the absorption of transportation function, in the process of bulb expansion, but also because of the squeeze pressure is greater. Will be subjected to more pressure, and is not conducive to the expansion of garlic, and is prone to the formation of lower commercial deformed garlic.
Select good garlic seeds
Select no disease residue appearance complete full single clove weight 5g or so garlic cloves for sowing, there are disease residue of garlic cloves in the sowing after easy to rot, and easy to cause further expansion of the spread of germs, not full of garlic buds themselves tend to be more weak, in the process of growth tends to be more small garlic, garlic yield will also be because of the small area of the leaf, photosynthetically active products and less Can not get enough nutrient accumulation and smaller volume.
The size of the garlic cloves is too large (more than 6g) after sowing will be strong, not only will the surrounding garlic seedlings caused by shading and lead to uneven seedling potential, but also in the formation of garlic, due to their own growth hormone levels are relatively high, often the new garlic head in the harvest before the dormancy directly began to sprout, the formation of the horse-tailed garlic resulting in the failure of the cultivation.
When choosing garlic seeds, should also take into account the sowing time, if it is the fall overwintering cultivation of garlic should choose the ability to withstand low temperatures of the white garlic is appropriate, if it is the spring cultivation or in order to get a high selling price in the morning market should be selected for a shorter growing period, harvesting earlier purple or red garlic, if it is the production of a single head of garlic should be selected for the red or red varieties of the skin.
Reasonable fertilization
Garlic cultivation in the application of adequate fertilizer on the basis of the "light before the heavy after the supplement" principle of fertilizer, the bottom fertilizer should be fully rotted farmyard manure, and with the application of nitrogen, phosphorus and potassium nutritionally balanced ternary compound fertilizer, in the spring before greening do not need to supplement the fertilizer, or a small amount of high nitrogen and high potassium compound fertilizer. High-potassium compound fertilizer, after entering the shoot period should be applied heavy fertilizer, the total amount of fertilizer in this period accounts for about 40-50% of the fertilizer of the entire reproductive period, in the late growth of garlic shoots after harvest, it is necessary to supplement the high-nitrogen and high-potassium compound fertilizer to promote the expansion of the head of garlic.
Organic fertilizer can provide 16 kinds of mineral nutrients necessary for the growth of garlic in a comprehensive manner, but not fully rotted organic fertilizer will continue to ferment in the application of the soil, resulting in seedling burning, seriously affecting the growth of garlic, while the commercial organic fertilizer will be due to the salinity is too high, aggravate the soil nourishing salinity obstacles, and make garlic in the later stages of growth is prone to loose cloves caused by the failure.
Chemical fertilizer is to meet the growth of garlic needs of nitrogen fertilizer, potash and other large elements of the important guarantee, the formation of garlic head plays an important role. In the winter before the application of too much fertilizer, especially too much nitrogen fertilizer will cause excessive growth, increase the risk of freezing during the winter, and in the garlic shoots began to draw, the garlic demand for fertilizer is at the maximum stage, if the amount of fertilizer is insufficient during this period, the leaf photosynthesis can not give full play to the function, the garlic head in the process of expansion can not get enough organic nutrients, and naturally it is difficult to form a larger head of garlic.
These are the first time I've ever seen a garlic head.
After the shoots, if you don't supplement the nitrogen and potash fertilizer in time, the function of the leaves will soon decline, and the ability of the aboveground part of the nutrient transport to the bulb will also be weakened, also not conducive to the formation of a larger garlic head.
Reasonable watering
Seeding water and cold water should be watered enough, the time to return to the green water should be early to a small amount of water, the amount of water should be enough to draw shoots in a timely manner, bulb expansion water should be timely. Moisture is the carrier of garlic nutrient transport and transformation (i.e., the proverb "harvest is water, harvest is fertilizer"), but in the various stages of garlic growth and development, the demand for water and fertilizer show significant differences.
Adequate bottom water is the basic guarantee for garlic to germinate quickly and ensure that the seedlings are strong, after pouring enough bottom water, we should carry out appropriate water control to promote the rapid and massive growth of the root system; pouring enough cold-proof water before overwintering can effectively prevent frostbite during the overwintering period; the green water can make the garlic grow back quickly in the early spring in order to prolong the growth of the growth of the time in the appropriate growth temperature conditions (not higher than 25 ℃), which is conducive to increasing the yield, but if the water is not enough to prevent frostbite, the garlic can grow back quickly in the early spring. The water supply is the key to efficient photosynthesis and yield enhancement; timely water supply after harvesting of garlic shoots can prolong the functional period of garlic leaves, increase the amount of photosynthesis products and promote the transportation of nutrients to the bulb.
In short, garlic to form a larger garlic head to achieve better grade and cultivation efficiency, is the cultivation of field selection, garlic seed selection and water and fertilizer management measures such as the result of the integrated role of these factors, any of these factors, any part of the negligence may result in a reduction in the yield of garlic and make it difficult to get the head of the garlic to be sufficiently enlarged and lower grade
