The Characteristics and Cultivation Techniques of American Red-Red Earth

American Red Globe Grape, also known as American Red, Late Red, and Big Red Ball, is a new high-quality grape variety developed by the California Agricultural University. Zhejiang Science and Technology Experimental Base of the Agricultural Bureau of Zhuji City has been successfully introduced since it was introduced and cultivated for three years. First, characteristic characteristics 1. Big ears, good growth. The red earth ear is extra large, loose, long conical, with an average ear weight of 800g and a maximum of 2500g. The medium growth potential is extremely productive and the fruiting rate is above 70%. In the second year after general planting, the average yield in the 3rd and 4th year can reach 2500kg/mu. 2. Excellent quality and good taste. The fruit is round to nearly conical, with a grain weight of 11-13g and a maximum of 22g. The fruit skin is bright red to purple, and the flesh is hard and brittle. The fruit is crisp and fragrant with a knife. The soluble solid content is as high as 17%-20%. Has a unique fragrance and no cracking. 3. Strong handle pull force, good resistance to storage and transportation. Longer stalks, strong fruit pieces with strong resistance to pulling force, can hold whole grains of grapes and lift the whole bunch of grapes. After the fruit matures, the trees can be preserved for 1-2 months. The low-temperature conditions and preservatives can be stored to the first In May of 2 years, the flavor has not diminished. 4. The market has a good market and high economic benefits. The US market has a very wide market and is popular among consumers. The general price is 20-30 yuan per kilogram, and the per mu output value is more than 20,000 yuan. Due to the shortage of resources, the market is in short supply. Second, the cultivation technology Red Globe grape is an ideal species in the United States grape, but because the species is Eurasian species, in the south when planting should pay attention to disease prevention, cultivation management should do the following aspects: 1. Reasonable colonization. Select a higher terrain, drainage and irrigation, smooth soil, deep soil, loose loam or sandy loam soil. In the south, the spring planting is appropriate. In February, the temperature rises back to the first half of the month for proper planting. The plant spacing is preferably 2.7-3ml-1.5m, and the double cross “v” rack or high-heavy “t” type rack is adopted. North and South to promote or shelter from rain. In order to make the Red Globe grape roots have a good growth environment, planting ditch and applying base fertilizer must be dug before planting. The standard for planting ditch is 0.5m (deep) 1m (wide), the raw soil is put on, the ripening soil is put down, and the ground layer is applied with crop straw. , Straw and coal ash, the middle layer of fully cooked chickens, pigs, duck dung and other farmyard fertilizer 4000-5000kg / mu, superphosphate 50-100kg / mu, mixed with soil and then applied into the ditch. Pruning the root system before planting, stimulating the roots of wounds, sterilizing sticks with lime sulfur, seeding and irrigating the root water, and burying the film to promote insulation and early rooting. 2. Plastic trim. Red Globe grapes have a strong growth potential and their apical dominance is obvious. The saplings grow and the shoots mature later, so pay attention to the balanced growth of the tree vigor. The double cross “v” type frame and the “t” type frame vines are the first topping at the height of 80-100cm to promote the first layer. Branching, at the height of 1.5m, the second topping promotes the second layer of branches, and the first and second layers of branches are tied to the wire, and the buds are applied and the heart is promoted to promote aging; when the winter branches are old Degree of maturity and thickness for clipping. As the red earth grape results in a moderate branching rate, the resulting tree is pruned with a pruning in the middle shoots, and the resulting mother branch is appropriately left with the full selection of shoots with full shoots and branches. 3. Flower and fruit management. The ear of red fruit is arranged closely and the parts of fruit that are pressed together cannot be normally colored. After 5-7 days of flowering, the shoots are topping and wiping the auxiliary shoots. Each result only leaves 1 ear. When the young fruit size is clear, the whole fruit is removed and the fruit with poor insemination, fruit shape and yellow color is removed. Granules, leaving a uniform fruit shape, bright green color of the fruit, leaving 60-80 per panicle, so that the distribution of fruit particles, and timely removal of the vice panicle, go to long spike tips, so that the weight per ear does not exceed 1000g . In order to improve the appearance quality of the ear, the fruit surface is smooth, and the bagging is performed when the fruit grows to the size of the bean. 4. Scientific application of fertilizer. Red Globe grape saplings are growing at seedling stage, and they are afraid of drought. After planting, sufficient watering is required. In those days, the seedlings were poured into fresh water at the early stage, once every 5-7 days, and the thin manure applied, the concentration gradually increased with plant growth. To promote the rapid growth of seedlings. In mid-August, the application of nitrogen fertilizers was stopped, and phosphorus and potassium fertilizers were applied. From May to August, 0.3% potassium dihydrogen phosphate, green fenwe and other extra-root fertilizers are added 1-2 times per month. Spraying is generally recommended after 3:00 pm, with the focus on the back of the spray. The results of tree topdressing should be re-applied budding fertilizer, suitable for swelling fruit fertilizer and coloring fertilizer, and appropriate increase in the amount of compound fertilizer, the best time for applying base fertilizer is one month after the grape is harvested, that is, from late September to October, because At this time, the growth temperature is higher, and the photosynthesis of the leaves is good. After the fertilization, not only the roots are easily healed, but also the tree body reserves nutrients are restored to tree vigor. Before sprouting, sufficient sprouting water should be sufficiently filled, suitable for swelling large water, appropriate water control during the coloring period, in order to increase the fruit sugar content and increase the morning color. 5. Pest Control. Due to the weak disease resistance of Red Globe grape, it is susceptible to blackpox, downy mildew and white rot. Before spraying in the early spring, 3-5 Baume degrees of lime sulfur or 200 times of sodium pentachlorophenol are sprayed. This is the key to wintering germs. The growth period is mainly to prevent and cure the blackpox disease, spraying once every 5-7 days, and can be controlled by Cobo, Dasheng, and Dubangfuxing at the seedling stage. Another thiophanate-methyl, fast-king, anthraquinone, US, mancozeb, etc. control botrytis, anthrax and downy mildew. For dinoflagellate moths, beetles and other pests can be used dimethoate, enemy killings, etc. for prevention, the above agents should be used alternately to avoid drug resistance.
