High-yielding cultivation techniques of garlic

1, fine soil preparation:

It is better to plant garlic with sandy loam rich in soil, fertile, porous, and well-drained organic matter. Try to avoid double weighting and not to make continuous crops with onion and garlic crops. Generally deep plowing 20 cm and breaking the bottom of the plow, fine leveling, building 1.5 to 2.0 meters wide, 20 to 30 meters long, dig a good drainage ditch, keep the surface smooth, soft.

2, deep base fertilizer:

Due to the long growing period, the garlic has a high population density and requires a large amount of fertilizer. Mu Shi quality rotted farmyard fertilizer 4000-5000 kg, Stanley "San'an" or 80-100 kg of garlic fertilizer, combined with soil preparation till 15-20 cm soil layer.

3, suitable species broadcast:

Garlic likes the cold climate, the best seedling age for winter is 4-6 leaf stage. In Shandong, it is generally appropriate to sow in the autumnal-cold-dew planting, timely planting is conducive to strong seedlings, the root system is well developed, and it is safe for winter to harvest garlic sprouts early and the yield is high. Sowing late, reduce the quality of garlic, or produce single head garlic.

4, rational close planting, pay attention to shallow broadcast:

"Slowly cultivating onions and cultivating garlic" is the experience gained by farmers for many years of practice. Garlic groove depth of 5-6 cm is appropriate, sowing depth of 3-4 cm, about 2 cm after sowing. Line spacing 15-20 centimeters, spacing 10-12 centimeters, 30-35 thousand plants per acre. If sowing is too deep and the tree is slow, the garlic will be small in the future and the yield will be low.

5, weeding and weeding:

After watering, the weeds sprouted in time to carry out cultivating, and weeding also broke the soil compaction and increased soil permeability.

6, scientific fertilizer management:

During the top-dressing period of garlic, it is generally divided into top-dressing fertilizers before winter, top-dressing fertilizers during returning to the green period, top-dressing fertilizers during the elongation period of garlic sprouts, and top dressing during the growing period of garlic. Topdressing should be combined with watering. The fertilizer and water should be used together to promote fertilizer and promote the growth of garlic.

1 Top-dressing before winter: Promote the rapid emergence of long-rooted seedlings after emergence and improve the overwintering performance of garlic. For the insufficient base fertilizer, it should be carried out 15-30 days after emergence. Mu can recover 8-10 kg of high-nitrogen compound fertilizer. The field with high fertility and sufficient base fertilizer can not use Miao Miao.

2 return to green manure: generally in the spring temperature rise, the garlic leaves and roots began to grow when applied, that is around the vernal equinox, acres of 8-10 kg high nitrogen compound fertilizer is appropriate.

3 moss fertilizer: Generally should be carried out in the scale buds and flower bud differentiation, garlic sprouts or dew exposure. At this time as the growth enters a vigorous period, the amount of growth and the amount of fertilizer required have reached a peak period. Therefore, the moss fertilizer is a key top dressing, accounting for 40% to 50% of the top dressing, and the Mudan Stanley sulfur compound ) Fertilizer (17-6-22, 20-5-20, etc.) 25-30 kg.

4 promote head fat: generally 25-30 days after the application of transpiration manure, with nitrogen fertilizer, with phosphorus and potassium fertilizer, Mu 15-20 kg of high-nitrogen compound fertilizer is appropriate to meet the garlic sorghum harvest and when the garlic dilate The need for nutrients. At the same time, the combination of disease prevention and spraying foliar fertilizer ensures the harvest of garlic.

Steroids Powder

Steroids Powder name of steroids is adrenocorticosteroids. The adrenal glands of normal people secrete a certain amount of steroids every day to maintain normal physiological functions in the body, such as regulating the metabolism of blood sugar, protein, fat and electrolytes. It is an essential hormone to maintain life.
Steroid is widely distributed in the biological community of a large category of cyclopentane hydrophenanthrene derivatives, also known as steroids, steroids. Steroid compounds do not contain bound fatty acids and are non-saponifiable lipids; These compounds belong to isoprene like substances, which are formed by cyclization of triterpenes through intramolecular reorganization and chemical modification.
