In recent years, as the price of grapes has risen steadily and the efficiency of planting grows steadily, the enthusiasm of farmers to grow grapes has gradually increased, and the investment in grape growing has also been relatively increased. The following are some of the unscientific methods that exist in fertilization. The fruit grower may wish to check it out to see if these problems exist.
First, the newly planted vines are fertilized early, causing dead seedlings to be planted in new vines. Generally, when the tendrils grow out, new roots grow. Excessive application of fertilizer before the new root grows on the one hand causes difficulty in the water absorption of the seedlings, on the other hand, it makes the new roots hard to grow. When it encounters high temperatures, the above-ground parts will die and die. Before the new root grows, it is only suitable for the foliage to supplement the nutrition. It can use urea water 500 times solution + Nonglaixin potassium dihydrogen phosphate 600 times foliar spray, spray once every 5 days, and even spray 3 times.
Second, after germination, it was found that the yellow leaves were heavily fertilized and watered. 65% of the nutrients from the germination to the flowering came from the storage of the tree in the previous year. At this time, the trees showed yellowing, mainly the accumulation of nutrients in the previous year. Insufficient, basically related to the weak and weak root system. In this case, on the one hand, it is necessary to loosen the soil and increase the ground temperature. At the same time, it is necessary to supplement the nutrition of the leaves. The above-mentioned foliar fertilizer application plan can be referred to.
Third, the yellowing of the treetops or the yellowing of the whole tree blindly supplements some of the vineyards, yellows the leaves of the treetops, and even the leaves of the whole tree are yellowish in color. The symptoms are very similar to iron deficiency, not necessarily iron deficiency in the soil. Most of them are cold and wet in the soil, poor in root respiration, weak in absorption capacity, and they are difficult to absorb iron and other elements. The first thing to be solved in this situation is the problem of soil permeability and root respiration, and soil loosening and dehumidification are effective measures. Physiological diseases are reduced, and production is increased.
Fourth, the more fertilization, the higher the yield. Many grape growers believe that the more fertilizer the grape grows, the better the yield will be. It is not true that vineyards that use high-concentration fertilizers have lower yields and worse quality than vineyards with medium and low-concentration fertilizers. When fertilizing near the trunk, it not only has low absorption and utilization, but also can easily cause burnout of rough roots, which has a great impact on tree growth. If a large number of rough roots died in the previous year, the spread of germs along the roots of death would result in the sudden death of the growing branches in the next year.
