Red grape is also known as red earth, Eurasian species. Originally produced in California, USA, it is a grape variety cultivated by researchers from California State University in the 1970s. Since the introduction of this variety in China in 1987, except for Heilongjiang and Jilin provinces in the northern region, the other provinces have introduced and cultivated, especially in the south of the northeastern region, and the cultivation in northern and northwestern regions is excellent and the fruit quality is excellent. , late maturity, storage and transportation, high yield, is the preferred high-quality and efficient variety of grapes.
Red grape
1. Moisture management: Red grape roots are shallow, drought-tolerant is not strong, and anti-caries ability is also poor. Timely and reasonable irrigation is very important. Generally, it is necessary to prevent drought in spring and early summer. The first irrigation before the germination of the grapes, also called germination water, is to promote the germination and tidy, the new shoots are strong. After the germination, the conditional place is filled with water for about 10 days.
2, fertilization: red grape is a large spike large variety, the demand for fertilizer during the growth period is greater. On the basis of applying the base fertilizer after harvesting the grapes in the previous year, the vineyard will apply germination fertilizer when the grape buds expand in the next spring. The main function is to promote the germination and tidy, the new shoots are strong, this time the fertilization is mainly based on the application of nitrogen fertilizer. Apply 20 to 30 kilograms of urea per mu or 5 kilograms of Shikang Notek (20-5-10).
3, branch management: red grape preparation buds sprouting strong, spring buds often form a phenomenon of sprouting multiple branches and multiple buds germination, so that not only the nutrient dispersion affects the growth of the main bud, and often The formation of branches is too dense, so it is necessary to smear in time after germination. When the bud is smeared, the germinated preparation buds are wiped off, so that only one strong bud is retained in one bud, and the weak buds on the branches and the useless buds on the old vines and the germination from the base of the trunk are also preserved. Corresponding hanging fruit buds.
4, the prevention and control of pests and diseases: white rot, germination using Fumei double 500 ~ 800 times liquid spray control; black disease, using difenoconazole 40-5000 times spray control; aphids: using 70% imidacloprid 8000 times spray Control; ground tiger: using 2.5% of high-speed flufenthrin 1000-1500 times spray control.

step 2: Immediately close the container again.
This protects the remaining test strips from humidity and guarantees strip integrity up to the expiry date indicated.
step 3: Dip the test strip for about 1 second into the fresh urine specimen.
Wipe off any excess urine on the rim of the vessel and blot the edge of the test strip on tissue paper.
step 4: Read the result by comparing the test fields with the color scale on the test pack after 30 to 60 seconds.
