1. Environmental choice: greenhouses should be built within 3 km of clean sources of pollution, in good environmental conditions, and the atmosphere, irrigated water and soil should meet quality standards for production of non-hazardous agricultural products。
Ii. Varieties selection: garlic species are best chosen for garlic-sized and petrified varieties. The white garlic in shandong and the purple garlic in the city of heilongjiang, which are highly productive, of good quality and more resistant to disease, are chosen。
Iii. Total fertilization and planting time: cleaning up before planting. Fertilized organic fattening of 10 to 15 kg per square metre is about 15 cm thick, and the bed is dredged. For management purposes, 150 to 200 centimetres wide and 15 to 20 centimetres wide. The planting time in the greenhouse is available throughout the autumn and winter, but it usually begins in late november, with a cut before new year's eve, a second cut before spring, or a first cut before spring. It can also be phased to focus on the market needs of new year's and spring's。
Iv. Company technology:
(i) pick garlic. Garlic should be used for the drying of garlic, normal growth of the penis, no frostbite and soft yellowing, 4 to 5 centimetres in diameter, equal size, and clean and tight garlic. Garlic has to be selected, graded, ploughed, and stored. If they are planted simultaneously, they shall be planted in different parts of the bed, after a different grade, in order to produce a whole seedling。
(ii) garlic treatment。
1. Garlic. Put the selected garlic in the tank for 12 to 14 hours, with a soft touch of the post-blow garlic. The good garlic was pulled out of the curtains and the water was taken seven hours later。
2. Garlic. I'm gonna dig up the root of the garlic and i'm gonna get rid of the garlic. When the garlic is used, it can be broken with a flat cone or with a nail, and then it can be inserted into the garlic root, and then it can be removed from it, and the garlic won't be scattered. Garlic makes garlic grow early。
Rubbish. Put the processed garlic on the greenhouses and plant it on the bed. And flatten the earth and flatten it with planks. Garlic should be tanned before it's too hot for the earth, so it's better in the afternoon. The order of garlic is arranged sequentially, as tight as possible and as flat as possible. Garlic can be filled with garlic. 15-17. 5 kg of garlic per square metre. If the bed soil is dryer, it shall be soaked with water; if the soil is wet, it may be tanned for one day and watered the following day, then covered with yellow sand from 3 to 5 cm. It grows green, white and of good quality. To make full use of the greenhouse, two layers of planting beds can be built。
Water and sand. The water must be applied flexibly in accordance with soil water content and the strength of garlic seedlings. Since garlic seedlings are grown primarily to consume their own nutrients, the moisture should not be too large to prevent rotting roots. The water is usually poured three times, for the first time after garlic; for the second time, when garlic is grown up to 10 cm; and for the third time, three to four days before harvesting. Care is taken to reduce the quantity of water each time it is poured down and the amount of water is appropriate. If the tip of the garlic seed is found and the leaves are yellow, this indicates a shortage of water and the need for partial recharge, but not too much water. In the second layer of garlic seedlings, water can be evaporated faster by space temperatures, which can be watered slightly more frequently. In order to increase the length of garlic, improve the quality and reduce the evaporation of the water, the soil should be sifted and sunscreened in two to three times and three to seven centimetres thick。
Temperature management. Then keep the indoor temperature a little higher, so that the seed of garlic and the seed of garlic may grow. The weather temperature is maintained at 25 °c - 27 °c and the shade at 14 °c - 15 °c, and the temperature is reduced to 10 °c - 20 °c before harvesting garlic. If the temperature is too high, the garlic seed is growing fast, leaves are thin and green, leaves are lost in water at severe times, are of poor quality, have low yield, and have an impact on output, and if the greenhouse temperature is below 15 °c ~ 18 °c, the garlic seed is growing slowly, affecting production. The winter greenhouses plant garlic seedlings, mainly to keep warm。
6. Garlic seed cut. The greenhouse garlic seedlings are managed at a suitable temperature for 20-30 days and can be harvested as much as 30 to 35 cm. After cutting his head, the second knife was cut for more than 20 days, when the garlic seed was as high as 30 cm. Two knives per kilogram of garlic harvest, yielding 1 to 1. 2 kg of garlic seed. When cutting a head, the knife may be laid at 0. 5 cm above the garlic head in order not to affect the growth of the garlic seed. Garlic slashes for a period of one to two days, so that the wounds can be healed and decomposition prevented. Garlic harvesting is best done in the morning, when it is produced in high quantities and of good quality to facilitate the timely supply of the market。
