How to apply formula fertilizer to garlic to save fertilizer and increase income
In 2005, 8 demonstration sites were set up in the three towns of Wangmiao, Yucheng and Lige and in Luotun Township, with 100-130kg of formula fertilizer applied per mu, averaging 121.9kg per mu (equivalent to N 17.1kg, P2O5 21.9kg, K2O 12.2kg), while a conventional fertilization control was also arranged, with an average of 129.4kg of compound fertilizer applied per mu (equivalent to N 20.7kg, P2O5 20.7kg, K2O 20.7kg,). At harvest, 5 sites were actually harvested and 3 sites were yield-measured, and the average yield per mu in the formula fertilizer demonstration area was 1485.

The Correct Way to Apply Sulfur Fertilizer for High-Yield Garlic
Garlic is a sulfur-loving crop. Allicin is mainly a disulfide compound. Most of the protein in garlic contains sulfur, and sulfur plays an important role in improving garlic quality. At the same time, studies show that only when the fertilizer N/S ratio is close to the optimal value can the nitrogen and sulfur absorbed by the plant be used most effectively. The N/S ratio in garlic is roughly 12/1. The utilization rate of sulfur in calcareous soils in the north is 2%-3%, and it is easily fixed as calcium sulfate, while the nitrogen utilization rate is 30%-35%. The optimal N/S is 4/5. Sulfur cannot be reused within the garlic plant, so sulfur must be supplemented in the middle growth stage to maximize the yield-increasing effect of the fertilizer. Choosing a suitable sulfur-containing fertilizer in production is the key to high yield. According to trials, applying 40% nitrogen-sulfur fertilizer (nitrogen-sulfur fertilizer contains N >= 17.5%, S >= 22.5%. Its fertilizer effect combines long-lasting and quick-acting effects, and the fulvic acid it contains plays an important role in promoting garlic root growth, improving disease resistance and fertilizer utilization rate, and eliminating soil compaction. It can combine root promotion and root nourishment, avoid premature aging and lodging of garlic, and achieve the production goals of increasing yield and marketability and building soil fertility) will be the best choice to meet garlic's needs. The specific fertilization methods are:

How to Apply Fertilizer Skillfully to Cotton? A Explanation of Practical Technical Points
Fertilizer is the material basis for high cotton yields, and applying fertilizer according to need is the highest principle of cotton fertilization. Where conditions allow, soil testing and fertilizer recommendation should be carried out, and based on the available nutrient content of the soil and the needs for high cotton yields, the type and amount of fertilizer to apply should be determined. For most cotton fields in the north, the amount of potassium fertilizer should be increased, the amount of phosphorus fertilizer reduced, and nitrogen fertilizer mainly used for topdressing, or a formula fertilizer with "high potassium, low phosphorus, medium nitrogen" should be applied. If a compound fertilizer with equal amounts of nitrogen, phosphorus and potassium is used, the amount per mu should not exceed 25 kg, plus an additional 12.5 kg of potassium fertilizer

How to apply base fertilizer in autumn? Master these technical points
I. Benefits of applying base fertilizer in autumn The time for applying base fertilizer in autumn is generally September-October in autumn. This is because this is a growth peak of the root system, wounded roots heal easily, and the level of nutrient reserves can be increased. In addition, at this time the temperature is high, the soil temperature is suitable, which is beneficial to microbial reproduction, beneficial to the decomposition of organic fertilizer and root absorption, increases the utilization rate of fertilizer, increases stress resistance, especially cold resistance, and helps flower buds continue to differentiate and become plump. Through full decomposition in winter, organic fertilizer can meet the nutrients needed for germination, flowering, shoot growth,

Key Technical Points and Correct Methods for Applying Boron to Cotton
In recent years, statistics from cotton boron fertilizer trials in various regions show that on boron-deficient soils (soil available boron below 0.5 mg/kg) and potentially boron-deficient soils (soil available boron below 0.8 mg/kg), applying boron fertilizer to cotton can achieve good yield increases. 1. Base fertilizer: Apply before cotton sowing or before transplanting nutrient (pot) seedlings, incorporated during land preparation. Apply about 0.5 kg of borax per mu, which can be mixed evenly with fertilizers such as nitrogen, phosphorus and potassium and applied together, or mixed with fine dry soil before application. 2. Seed fertilizer: At cotton

Methods for Breeding Introduced Pig Breeds and Key Points for Applying New Breeding Technologies
The continuous development and progress of science and technology have made it possible for people to explore natural laws and reveal biodiversity. The greatest advancement in pig breeding in the 20th century was breaking through 800 g/day in daily weight gain, achieving a lean meat rate of over 60%, a feed-to-meat ratio of 2.8:1, and slaughter pigs reaching over 90 kg body weight at 156 days, producing truly lean pigs. In recent years, with the continuous development of breeding theory and practice, pig breeding in countries with developed pig industries has gradually transitioned from breed selection to specialized composite line breeding, targeting different uses of each line in the crossbreeding system

How to apply top dressing in the later stage of edible fungi? These methods must be mastered
In the later stage of mushroom fruiting, in order to enhance the stamina for fruiting, mushroom growers often use various means to add nutrient solutions for top dressing. But only by using the correct method of addition can the expected goal be achieved. Otherwise, it is like pulling up seedlings to help them grow, achieving the opposite effect and bringing losses to producers. 1. Pay attention to the method of addition. There are usually three methods for adding nutrient solution: spraying, soaking and filling holes. The time for spraying nutrient solution is suitable when fruiting bodies appear in large numbers. When spraying, care should be taken that the nozzle is not directly facing the fruiting bodies, and at the same time pay attention to the "four no-spray" rules:

A Detailed Guide to the Correct Way to Apply Eye Drops to Dogs
Common eye diseases can all cause tearing or excessive discharge. If left untreated, this discharge will inevitably soil the hair on the dog's face. Before applying eye drops, first use damp cotton wool to carefully wipe away the dirt at the corners of the dog's eyes. Wash the dog's eyes with warm water or eye wash prescribed by a veterinarian. Human eye drops must not be used. Be careful not to get cotton fibers into the eyes. Gently hold the dog and open its eyes; to keep the dog from being frightened, apply the eye drops from behind its head. After applying, let the medication remain in the eye for a little longer.

Lessons to Remember After Losing Out by Not Applying Organic Fertilizer to Jujube Trees
This year, the selling prices of jujubes varied greatly. The price differences were mainly due to differences in sweetness and crispness, and apart from varietal characteristics, the main reason for the differences in sweetness and crispness was the different types of fertilizer applied. Currently, it is the second root development period for jujube trees. The first root growth peak occurs from late May to early June after new shoots stop growing, and the second root growth peak occurs from after fruit harvest to early November. From surveys of jujube growers, many farmers are only accustomed to fertilizing fruit trees in spring,
