Walnut cut-and-row planting refers to the planting of walnut seedlings. If the grafted seedlings are planted, they will be cut at 2 cm above the grafting interface. If the walnut seedlings are planted, they will be cut at 2 cm above the surface after planting, and then cut at the cut. A method of planting 3-5 cm of covering soil above the cutting edge. The planting method has been proven by the author for many years and has the following advantages:
1. The survival rate is high. When walnut seedlings are grown, the density is generally larger and the fertilizer and water phases are also used more. However, the leaves of the walnut itself are large, and the ventilation conditions of the light and seedling fields are extremely poor. Therefore, the maturity of the shoots is low, especially the excellent grafted seedlings are grown due to growth. Shorter time, lower maturity of the shoots, large and multi-walled walnut stalks, low cortex waxiness when shoots are low, and normal planting, walnut seedlings often severe water loss, survival rate is low. Walnut cutting and planting not only greatly reduces the area of ​​evacuation of seedlings, but also protects the soil and protects the water, which creates a good condition for the survival of seedlings.
2. Save time, effort, and ease of use. In the past, after walnut planting, in order to prevent seedlings from drawing and freezing, more measures such as putting plastic tubes for the seedlings, burying soil, trunk coating, or wrapping the leaves of trunks were used to prevent stripping, cold-proofing, time-consuming and laborious, and sometimes to the seedlings. damage. After the walnuts were cut and planted and planted, cut a pair of scissors and put the two soils together.
3. After the planting, the seedlings will not grow, the seedlings will grow stronger, grow neatly, and later be pruned and standardized. After the walnuts are cut off, there are only buds on the seedlings, and the buds only sprout when they grow new roots and have greater capacity to absorb water and nutrients. At this time, the aboveground and underground growth of the seedlings is coordinated. Will not slow seedlings. In addition, timely eradication of weak buds after germination, leaving only a strong bud, the seedlings themselves are all stored only to provide this strong bud growth nutrition, so the growth potential is both strong and neat, very conducive to plastic trim.
4. Both cold and night cream. Covering the soil has played a role in preventing the cold, and the buds sprouted late and missed the night cream.
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.
