How to grow spring-planted garlic for high yields? Master these four cultivation points
Garlic planted in spring and harvested in summer has a shorter seedling stage and less nutrient accumulation, so both yield and quality are inferior to autumn-planted garlic. To improve the yield and quality of spring-planted garlic, you must select good varieties and focus on management. The key is to do well in the following four aspects: 1. Choose suitable varieties: spring-planted garlic takes about 100 days from planting to harvest, and the whole growth period is very short, so choose short-growing-period purple-skin garlic as seed garlic. 2. Apply heavy base fertilizer: before sowing, while preparing the land, apply 3000 kg of high-quality human and livestock manure or barnyard manure per mu, 15:

Key Technical Points for Spring Field Management of Garlic
Water and fertilizer management after garlic turns green again is the key to a bumper garlic harvest. As the weather warms up, water and fertilizer uptake gradually increases after greening. Especially during the bolt-bearing stage and the bulb enlargement stage, garlic has its peak demand for water and fertilizer. Therefore, throughout the entire growth period of garlic, irrigation and topdressing should be carried out in a timely manner according to soil moisture, soil fertility and seedling conditions, with particular emphasis on watering the "three waters" well and applying the "three fertilizers" well. 1. Water the greening water well and apply the greening fertilizer well. By the Spring Equinox, garlic seedlings begin to turn green and grow. Because early spring soil temperatures are low, it is best to water the greening water at noon

Detailed Explanation of Key Garlic Spring Management Techniques
I. Management during the regreening stage: After Awakening of Insects, garlic begins to regreen, so it should be watered and fertilized promptly. Along with watering, apply 20 kg of diammonium phosphate per mu or 25 kg of ternary compound fertilizer. Then carry out shallow hoeing to loosen the soil, raise the temperature, and preserve moisture. Around Qingming Festival, when yellow tips appear on the leaves, carry out the second topdressing promptly and increase the frequency of watering, generally watering once every 10-15 days, to promote plant growth. II. Management during the garlic scape growth stage: In early May, garlic scapes begin to differentiate. After the Beginning of Summer, garlic scapes enter a period of vigorous growth, and during this period fertilizer and water management should be increased.

Key Technical Points for Spring Fertilizer and Water Management of Garlic
After garlic turns green again, its absorption of fertilizer and water gradually increases. Especially during the bolting stage and the garlic bulb enlargement stage, these are the peak periods of fertilizer and water demand. In terms of management, emphasis should be placed on watering the "three waters" well and applying the "three fertilizers" well. Water the green-up water well and apply the green-up fertilizer well. In spring, the soil temperature is low, so it is best to water the green-up water at noon to promote early seedling growth. Along with watering, apply 15-25 kg of nitrogen-phosphorus-potassium compound fertilizer per mu or 15 kg of potassium sulfate, then control water appropriately to promote root development. Water the bolting-promoting water fully and apply the bolting-promoting fertilizer heavily. Late March to early April is the period of rapid differentiation of garlic flower buds and clove buds

How to prevent rice field eel diseases in spring? Garlic and salt solution works well
After overwintering, rice field eels begin to become active in spring when the temperature rises. At this time, they are very susceptible to saprolegniasis, skin rot disease, bacterial septicemia and other diseases, which can lead to death. If a clarified solution made by soaking fresh garlic and high-quality salt at an 80-100 fold dilution is promptly splashed into the breeding pond, once every 3-5 days, for 2-3 consecutive applications, splashing 2-3 kg per square meter of breeding pond each time, evenly sprinkled on the water surface, the rice field eels will not be infected by the above diseases, and the breeding survival rate will be high.

What are the key technical points for spring garlic management?
Around Jingzhe (Awakening of Insects), as temperatures rise, Cangshan garlic enters the regreening growth stage; around the Spring Equinox, it reaches the rotting-mother stage (also called the mother-returning stage). Due to the continuous low-temperature and drought weather from last winter to this spring, garlic growth has been affected, the seedling condition is poor, and there are more garlic fields with weak seedlings, so management must be strengthened. I. Regreening stage management. Before and after regreening, spray once with a plant growth regulator or amino acid foliar fertilizer to enhance stress resistance and prevent damage to garlic from late spring cold. After the Spring Equinox, garlic is in the rotting-mother stage, during which garlic maggots are prone to occur, so pay attention to spraying pesticide to control seed

Detailed Explanation of Key Technical Points for Early Spring Management of Garlic
Spring field management of garlic mainly refers to the management from after the spring temperature rises until the harvest period. This period is exactly when the garlic bulb expands, and it is also a period when diseases and pests occur frequently. Therefore, doing a good job of management during this period is of great significance for a bumper harvest of garlic. 1. Fertilizer and water management: The application of fertilizer should grasp the principle of supplementing vigorous growth and promoting weak growth. At the same time, irrigate well with the "two waters," namely the green-returning water and the bulb-expanding water. Generally, after garlic returns to green, plots with vigorous growth should be given little or no fertilizer; for plots with yellowing seedlings and weak growth, combined with watering, in

Detailed Explanation of Key Points for Spring Management Techniques of Onions
I. Watering: Onions are generally not watered during the overwintering period, and there are no pests or diseases. In March to April, water lightly once with green-returning water; when entering the vigorous leaf growth period, appropriately increase irrigation; about 10 days before bulb expansion, carry out seedling control to suppress leaf growth; when there are 6 functional leaves, water thoroughly once, then control seedlings for 10 days to prevent excessive plant growth from affecting bulb expansion. After seedling control, the bulb begins to expand, which is the key period for topdressing and watering. However, because the temperature rises during this period, evaporation and plant growth are large, and it is the period with the highest water demand, watering should be frequent, often keeping

Detailed Explanation of Key Cultivation Techniques for Upland Rice in Spring in Both Northern and Southern Regions
I. Early-Stage Management Techniques for Early Rice Production in the South China Rice Region Currently, it is necessary to focus on drought resistance and protecting spring plowing, and to seize the opportunity for transplanting and planting. In the southern region, early rice should be transplanted around Qingming; in the central region, around Guyu; and in the northern region, before "May Day." The following technical measures should be mainly adopted: 1. Apply sufficient basal fertilizer and transplant sufficient seedlings, and apply tillering fertilizer early and heavily. On the basis of applying good seedling-departure fertilizer to the seedling field, apply 30 kg of ordinary superphosphate, 7.5 kg of potassium chloride, and 25 kg of ammonium bicarbonate per mu as basal fertilizer. Where conditions permit, apply 1000-1500 kg of high-quality farmyard manure per mu. Throw or transplant 21,000-25,000 hills per mu; for hybrid rice, two seedlings per hill (two grains), and for conventional rice, 4-6 seedlings per hill. 5-7 days after throwing or transplanting, apply 5-6 kg of urea per mu as tillering-promoting fertilizer; 12-15 days after throwing or transplanting, apply about 7.5 kg of urea and 7.5-10 kg of potassium chloride per mu, or 12.5-15 kg of compound fertilizer per mu as strong-tillering fertilizer.
