In the garlic planting technology,there are a lot of work that needs to be paid attention to when planting garlic.Here are five key points of the garlic planting technology.
The five main points of garlic planting technology are introduced as follows.
In the garlic planting technology,the main varieties currently suitable for planting in the Kirin area are Sichuan Hongqixing(1st and 2nd generation),soft-leaf garlic,first grade early,second grade early,local purple garlic,etc.
Bazi area is usually early garlic seedlings,red seven stars(first generation,second generation)planting time is in Bailu Festival(early September).The second best early sowing period is before and after the autumnal equinox season(mid and late September).The late garlic sowing period should be from autumn equinox to cold dew(ie September 23-October 8).High-altitude areas can be planted one season in advance.
Before sowing,first select and classify the garlic cloves,remove the garlic cloves infested by diseases and insect pests,and separate them by large and small to grade and sow.
(4)Moisture preparation and reasonable planting
When preparing soil moisture,it is required to be thin and thick,and the width of the soil surface is 3-4 meters wide.In the garlic planting technique,planting should not be too deep,and the soil must be kept moist to promote early emergence.Red Qixing needs 100-120 kg per mu,other garlic varieties are small,only 60-75 kg per mu,density of 30,000-40,000 plants per acre,row spacing 15-18 cm,plant spacing 8-10 cm,Early-maturing varieties are dense and late-maturing varieties are rare.
1.Weeding and loosening soil:If the soil is hardened and weeds grow after the garlic emerges,weeding should be combined with weeding.When the seedling height is 10-13 cm and there are 2-3 leaves for the first time,the seedling height is 26-33 cm When there are 5-6 leaves,the second shallow plowing is carried out.In the garlic planting technology,weeding is more laborious in garlic fields.In order to improve the effectiveness,chemical weeding should be promoted.The chemical weeding is:3 days after the garlic is planted,spraying the herbicide with Guoer and chlorpyrifos,after emergence Tillage should be done 1-2 times to prevent soil compaction and weed growth.If there are many weeds at the seedling stage,different herbicides can be used to control the weeds once.
2.Irrigation:After the garlic is sown,if the soil is moist,the seedlings can be emerged without irrigation.When the soil is dry,the seedling water should be irrigated once.In the seedling stage,water should be irrigated and cultivated more,and the water should be properly controlled to prevent the long legs and the"withdrawing mother"from being premature.In the period of bolting and bulb hypertrophy,increase irrigation to avoid drought and keep the soil moist.Irrigation should be dominated by furrow irrigation.The water will not be drowned over the surface of the soil,and the soil tide will be withdrawn immediately to avoid flood irrigation.The irrigation should be stopped 5 to 7 days before the garlic head is harvested,otherwise it will be easy to produce loose petals.
3.Fertilization:Garlic has a long growth period and requires a large amount of fertilizer,but its root system is shallow and its ability to absorb fertilizer is weak.Therefore,it is necessary to apply plantar fertilizer and top-up fertilizer in stages to continuously meet the needs of garlic growth and development.Garlic fertilization should be based on organic fertilizer,which accounts for 70%of the total fertilizer.The ratio of nitrogen,phosphorus,and potassium is 1:0.8:1.It is about 12.5 kg of pure nitrogen per mu.Pay attention to supplementing calcium-containing fertilizers and adding boron fertilizers.For fertilization,you can use the"one clear"or heavy bottom early chasing method.Generally,30 kg of compound fertilizer(15:15:15)is added to the base fertilizer for pigs and 50-80 pounds of pig manure is added.After the mother is withdrawn(about 5 leaves after emergence),the fertilizer will be raised once.In the round foot stage(after 8 leaves),20 kg of urea or 30 kg of ammonium bicarbonate can be applied per mu.
4.Diseases and pests prevention:During the growth of garlic,especially after December,there are many cold waves,low temperature and low exposure,and high humidity can easily cause garlic pests and diseases.In garlic planting technology,the main diseases are rust,leaf blight,and blight.Control agents:fentrochlorin,chlorothalonil,diazepam,and sacralin,can be applied at the early stage or during the onset of the disease;the pests are onion thrips,and trichlorfon can be used for fighting.After the beginning of spring,as the temperature rises and sunshine increases,garlic enters a rapid growth stage.At this time,the most fertilizer and water are needed.Attention should be paid to seedlings to supplement fertilizer and timely irrigation.At the same time,reduce the field temperature to meet the needs of garlic growth.
