Although the reproductive process of welsh onion is relatively simple, the technical requirements of field management are relatively high. In order to achieve high yield and high quality, the management measures are summarized as follows:
1. Early planting and early transplanting, and proper planting is the key. Many years of production experience have shown that early transplanting welsh onion has significantly improved yields compared to late transplanting onion. In addition, reasonable close planting is an important measure for high quality and high yield of welsh onion, generally with a plant spacing of 4-6 cm and a row spacing of 25-30 cm.
2. Weeding grass should be timely to prevent locusts from causing rot. The cultivator can promote the growth of welsh onion roots and increase the permeability of the soil. Onion cultivars are in season when the temperature is high and the rainfall is heavy, and there are many kinds of weeds. Therefore, weeding must be done in time to prevent the grassland; in July and August, the northern region is concentrated. During the rainfall period, it is easy to cause scallions roots, yellow leaves, and dry tips. In addition to preventing waterlogging, it is also necessary to break the table and scatter early so that the roots of scallions can perform various normal activities.
3. The top-dressing fertilizer should be applied properly, and high yield and quality are guaranteed. Based on the fertility characteristics of local green onions and the local fertilization habits, generally 30 kg of “Tianji†phosphorus and potassium nitrate are applied per acre, and 30 kg of “Tianji†phosphorus nitrate is applied in 7-8 months, and then applied in the following month. 25 kg of Phosphorus Nitrate.

Reader Urinalysis Reagent Strip
Urine test strips include test parameters for Nitrite, PH, Glucose, Protein, Occult Blood, Ketone, Bilirubin, Urobilinogen, Specific Gravity, Leukocyte, Ascorbic Acid, Ca, Creatinine and Microalbumin.
Urinalysis Test Strips Parameters is a basic diagnostic instrument used to determine pathological changes in the urine of standard urinalysis. urine test strip comprise of up to 12 different chemical pads or reagents which react (change color) when immersed in, and then removed from, a urine sample.
The test can be read between 60 and 120 seconds after dipping. Routine testing of the urine with multiparameter strips is the first step in the diagnosis of a wide range of diseases.
A wide range of applications, such as fitness, sports,drinking water, food, cooking oil
[Test Result Explanation]
Urobilinogen:This test area will detect urobilinogen in concentrations as low as 3μmol/L (approximately 0.2 Ehrlich) in urine.The normal range with this test is 3-16μmol/L.A result of 33μmol/L represents the transition from normal to abnormal, and the patient and/or urine specimen should be evaluated further. The negative results of this test cannot determine that there is no urobilinogen in samples.
Bilirubin:Normally no bilirubin is detectable in urine by even the most sensitive methods.Even trace amounts of bilirubin are sufficiently abnormal to require further investigation.Metabolites of drugs which give a color at low pH,such as pyridium and lodine etc,will interfere with the test of bilirubin,high concentration of ascorbic acid may cause false negative.
Ketone:The test strip reacts with acetoacetic acid in urine.It does not react with acetone or B-hydroxbutyric acid.Normal urine specimens usually yield negative results with this reagent,false positive results may occur with urine specimens which containing pigment or large amounts of levodopa metabolites.
