How much is a jin of garlic in 2019? Plus garlic topdressing techniques

The whole garlic plant has a strong pungent taste. It can be eaten as a vegetable, used as a seasoning, or used as medicine. Eating it regularly has health benefits for the body, but it should not be eaten too much, and the amount should be controlled every day.Let's take a look below at roughly how much a jin of garlic cost in 2019, and what the key points of topdressing techniques are.

1. Roughly how much did a jin of garlic cost in 2019?

Data show that on November 4, the average price of ordinary garlic at the Beijing Xinfadi Agricultural Products Wholesale Market was 4.2 yuan per jin, up 13.51% cumulatively from 3.7 yuan on September 28. The recent rise in garlic prices can be said to be a normal reflection of market supply and demand. Because new garlic prices rose, the old garlic left over from last year caught a good opportunity, and trading volume increased, which played a certain supporting role in stabilizing garlic prices.

The price of old garlic was about 0.8 yuan per jin lower than that of new garlic, and the trading volume increased considerably compared with previous years.

2. What are the key points of garlic topdressing techniques?

Generally, autumn-sown garlic has a relatively long growth period, requiring 8-9 months. After the differentiation of bulbils and flower buds, it is the peak period for nitrogen, phosphorus and potassium nutrient uptake in the entire life of garlic. During this period, the leaves are lush, the scape grows and develops quickly, the yield is high, and the demand for fertilizer and water is large and concentrated. Professional growers say that for every 100 kg of garlic heads produced, garlic needs to absorb 1.42 kg of nitrogen, 0.44 kg of phosphorus and 0.99 kg of potassium. At different growth and development stages, there are also great differences in the amount and proportion of nitrogen, phosphorus and potassium nutrients absorbed.

Generally, scientific and reasonable fertilization needs to be carried out according to the level of soil fertility and the needs of garlic at different growth stages. Grasp the fertilization principle of “light at the early stage, heavy in the middle, and supplementary at the later stage”, which should not only prevent excessive rampant growth in the early stage, but also avoid fertilizer deficiency and premature senescence in the later stage.

Garlic planting plots need deep ploughing and fine harrowing to enhance soil permeability, which is conducive to the activity of soil microorganisms and the transformation of soil nutrients, improves the soil's storage capacity, and is beneficial to well-developed root systems and bulb expansion.

1. Skillfully apply the differentiation and bolting fertilizer

When garlic enters the differentiation and bolting stage, vegetative growth and reproductive growth proceed at the same time, and the demand for phosphorus is strong. This is also the most critical topdressing of garlic's entire life. Wait until the garlic scape emerges (shows its tail), then apply 15-20 kg per mu of high-phosphorus and high-potassium compound fertilizer, dissolving it first before flushing application.

2. Apply jointing fertilizer heavily

Garlic is different from other crops. When the climate is normal, for garlic at the green-turning stage, field management is generally not carried out, to avoid a sudden drop in soil temperature caused by watering too early, which can trigger a major outbreak of bacterial soft rot and affect the growth of garlic. Therefore, the first topdressing should be carried out at the jointing stage, with 20-25 kg per mu of nitro compound fertilizer. After an interval of 15-20 days, apply the second fertilizer, with about 20 kg per mu.

3. Supplement medium and trace element fertilizers

Medium and trace elements such as calcium, magnesium, iron, manganese, zinc, copper, etc. are all essential for the growth and development of garlic.
