Introduction of grapes must be "10 look"
Every winter until the winter, seedlings ads fly. According to statistics, in 2002, among all types of advertisements, there were more than 160 nucleated vines and more than 30 nucleus-free cultivars. In order to help the majority of peasant friends choose the right variety of grapes, they should avoid detours and remind everyone to introduce the grapes when they are introduced: A look at the planting area and economic conditions. Each species has its regional adaptability, and it is necessary to cultivate the varieties regionally. In the Yangtze River valley, it is best to choose the European and American hybrids with strong disease resistance in open field cultivation; if the economic conditions are good, then you can choose the Eurasian species with weak resistance, large grain, and high quality, but you must use facilities for cultivation (protecting rain or greenhouses) . Second, look at mastery of technology. Those who have already had better cultivation techniques can choose high-end varieties with high market prices and difficulty in cultivation; those who have not yet mastered cultivation techniques should choose easy-to-manage European and American hybrids, and at the same time introduce a few high-grade Eurasian species. Third, look at market positioning. If it is sold to big cities and supermarkets, we should choose high quality Eurasian species with good quality, storage and transportation, and we also need to have a certain scale of planting. If we sell at a nearby or rural market, we should choose high yield, manageability, and large grain. European and American hybrids. In addition, according to the market's consumption habits, select strawberry flavor or rose flavor, rock sugar or sweet and sweet varieties. Four to see the source of the variety. To figure out which species the selected species is, where it originated, came from hybrid or budding. At present, the market for nursery stocks in China is still very unregulated, and the phenomenon of cross-extension of the same thing is very prominent. Some seedling dealers use fake goods and shoddy goods to swindle customers and profiteers. Introducers must pay attention to screening. Fifth, look at the botanical features. Each species has its own special botany characteristics, and a species can be identified and judged based on the botany characteristics of the species. In general, the appearance of large populations varies greatly, while the difference in the appearance of the same population is small. Some domestic seedling merchants sell many similar and similar species of the same species as new varieties, which are hard to prevent. Six to see biological characteristics. When selecting a variety, it is necessary to understand its growth potential, disease resistance, high yield and budding, flowering, maturing and other biological characteristics. Some false advertisements say that high yield is poor and high yield; strong resistance is not resistant to disease; late varieties are said to be early maturing varieties, etc. Seven to see the fruit traits. When selecting a variety, it is necessary to know the average ear weight, grain weight, fruit setting rate, soft or brittle flesh, whether it is easy to color, whether it cracks fruit, threshing, whether it is resistant to storage and transportation and other fruit traits. Some advertisements or nursery stock merchants generally exaggerate their weight. When publicizing, they only talk about the merits of the variety, and do not speak about shortcomings. Many varieties have only one drawback, and even if other comprehensive traits are good, they will limit their development. Eight see Miao units. To go to the formal seedling production units to purchase seedlings, to understand whether the seedlings are registered and issued by relevant departments, business licenses, seedlings business licenses, seedlings quarantine permits, etc. are complete, whether there is a nursery, how large the scale, seedling purity can be Guaranteed and so on. Nine to see whether seedlings are grafted seedlings. Grafting seedlings generally use high-resistance rootstocks, while southern and northern grapevines have very different resistance requirements. The north requires cold and drought resistance, and the south requires moisture and disease resistance. If the red earth self-rooted seedlings are susceptible to root cancer, resulting in a large number of dead seedlings, such as the selection of resistant rootstocks, this disease can be avoided. Ten to see if there is a successful result park. When selecting a variety, it is best to choose a variety that has been successfully cultivated. Each species has its own unique traits, and good methods can improve the economic benefits. We cannot pursue the "new, extraordinary, special" variety. It takes about five years to truly grasp the characteristics of a breed. So far, there is not a perfect variety. Each breed has its own advantages and disadvantages, but some of its shortcomings are insurmountable and the key to successful cultivation. Only by understanding the characteristics of breeds, and then avoiding weaknesses, can we obtain good economic benefits.
