High-yield planting techniques of garlic

Although the garlic market is very poor in 2018, it still can't stop many farmers from choosing to grow garlic. In their words, although this year's market is not good, but catch up with a good year, before the loss will also return to the original. For friends who still choose to plant garlic this year, what the earth flow net can do here is to suggest a little garlic planting high-yield planting technology, so that everyone can achieve high yield next year and harvest a bumper harvest.

For garlic, the growth period is basically 220-280 days. There is also a saying in the folk that "poor people do not plant garlic", which means that if you are reluctant to invest, don't plant garlic. The garlic root system is underdeveloped and the root layer is shallow. It is sensitive to soil water and fertilizer. If you want high yields, you must give enough fertilizer!

1. Soil preparation and fertilization

Garlic planting is still based on the basic fertilizer, supplemented by topdressing program, at present, the market is still relatively short of long-term fertilizer, and for garlic such shallow root crops, chemical fertilizer use no matter how large, it is difficult to play a greater role in fertilizer efficiency.

Therefore, in the stage of soil preparation and fertilization, Scientific Xingnong suggests to choose the scheme of farm manure (organic fertilizer) combined with slow-release compound fertilizer. For ordinary chemical fertilizer, the fertilizer effect is released too fast and cannot play a good role. Over-plowing is OK for garlic cultivation, but not necessary. Because garlic roots are shallow, there is no need for deep ploughing.

About organic fertilizer science to promote agriculture remind, many friends chose not decomposed chicken manure, pig manure as fertilizer, leading to the second year underground pest flooding, especially maggots, so this point must be noted.

II. Topdressing

Garlic has a long growth period and a shallow root system. Therefore, after the spring planting garlic that piece of land, the base fertilizer is almost consumed. Timely topdressing can ensure the healthy growth of plants. The topdressing is mainly nitrogen fertilizer, phosphorus and potassium fertilizer as auxiliary, of course, if you choose to apply compound fertilizer, the effect may be better. Foliar spray can be used to promote absorption and improve garlic quality.

1. Topdressing at garlic bolting stage

Generally, it is also relatively dry in March and April. At this time, garlic is about to sprout, and the demand for nutrition and water and fertilizer is relatively large. Garlic also needs watering. At this time, topdressing can be combined with watering. The first crop of water in the period of returning green of garlic should not be watered too early, otherwise it is easy to cause freezing damage in late spring cold, resulting in garlic yield reduction. Humic acid soluble fertilizer can be selected to improve fertilizer efficiency when topdressing.

2. Fertilization during garlic expansion period

At this time, the nutrition supply of garlic is mainly transported to the underground bulb, which promotes the expansion of garlic head. This period is also the key period for high yield of garlic. Water and fertilizer management is especially important. Because garlic likes sulfur and needs high potassium fertilizer at this time, it is suggested to apply UN potassium dihydrogen to improve not only the quality of garlic but also the yield of garlic. Of course, phosphate fertilizer is also very necessary. At present, there are water-soluble phosphate fertilizers on the market. Foliar spraying can be selected to improve fertilizer efficiency.

The above is a little fertilization technology introduced by the soil flow network Xiaobian for everyone, I hope to help everyone, I hope next year garlic can have a good price, garlic harvest.
