There are many kinds of garlic planted in Shandong Province. In jinxiang garlic, for example, the garlic yield is generally around 1, 200- 1, 300 kg/mu under conventional cultivation. In order to improve the garlic yield, 20 kg ammonium sulfate can be applied when garlic seedlings are exposed to the ground for the first time 1 time, and the soil can be covered for 3-5 cm after underwater infiltration. At the same time, the temperature in the shed should be kept at 20-25℃ during the day and around 15℃ at night.

1. What is the garlic yield per mu in Shandong?

1, garlic yield per mu in Shandong

Taking jinxiang garlic as an example, under the conventional planting conditions, the yield per mu of this variety is generally around 1200- 1300 kg. 20 10, the yield per mu of this variety1282kg; 202 1, the average yield per mu of this variety 1240 kg.

2. How to increase garlic production

(1) scientific soil covering

(1) When the young garlic shoots are exposed, pour 1 time water (thoroughly), and cover the soil with 3-5cm after the water seeps down. When the young garlic shoots are exposed again, water 1 time, and cover the soil for 3cm again.

② After continuous operation for 3-5 times, the seedling stem can reach about 10- 15cm, which can not only increase the yield, but also improve the quality of garlic.

(2) Rational fertilization

(1) When garlic seedlings are exposed for the first time 1 time, 20kg of ammonium sulfate or diammonium phosphate can be applied in coordination with watering.

(2) If the seedlings grow strongly, no topdressing is needed; If the seedlings grow slowly or weakly, 20 kg of ammonium sulfate should be applied before covering the soil. It should be noted that the fertilizer should be dissolved in water before pouring, and it is not allowed to be poured after pouring.

(3) control the temperature reasonably

(1) The temperature in the shed is controlled at 20-25℃ during the day and around 65438 05℃ at night.

(2) when the temperature is high, it should be ventilated and cooled in time to prevent garlic leaves from turning yellow and rotting. If the weather is cold, cover the garlic at night to prevent freezing.
