Apple is one of the major fruits and fruits consumed in China, and it is also the main source of income for the majority of farmers in apple production areas. However, the problem of late spring and small size has severely hampered the development of the apple industry and brought huge losses to the majority of farmers. How to improve the apple tree's resistance to the cold and the ability to stabilize production has become an urgent problem to be solved.
Analysis of the Cause of Apple's Size Year
Malnutrition and nutritional deficiencies, poor root development. Because the production and distribution of organic nutrients produced by the leaves and the need for the construction of flowers, fruits, roots and flower buds, and the inconsistency between quantity and time, the phenomenon of annual size of fruit trees has been formed: In the years when there are many results, the nutrients Continually transported to the fruit, the nutrients of other organs of the tree, especially the top buds of the shoots, are greatly reduced, resulting in the inability to form flower buds in the year, so it is a small year after the big year; while there are few young flowers and nutrients are accumulated in the tree. The increase has created good conditions for flower bud differentiation. As a result, fruit production has risen sharply in the following year. This is repeated, forming a cycle. In addition, unreasonable cultivation techniques, extensive management, poorly-developed root systems, declining tree vigor, untimely pest control, improper trimming, and so on are the causes of years of age.
Hormones in plants are not balanced. Endogenous hormones such as ethephon, auxin, and abscisic acid in plants control the vegetative growth and reproductive growth of plants. The balance between them affects flower bud differentiation, fruit set, and fruit development. The role. As a result of more years, the total number of seeds in the tree increased accordingly, and a large amount of gibberellin was synthesized in the embryos, which could induce the production of amylase, hydrolyze the starch and promote the growth of new shoots, inhibit the formation of flower buds, and make the next year smaller. year. solution
Here, we recommend the use of a high-tech biotechnology product from Germany, “Biacareâ€, for the majority of farmers. A large number of production practices have proved that "Bia-Ying" can well regulate nutritional balance, enhance tree vigor, and promote the absorption of fertilizers by plants while promoting the growth of new roots. In addition, "Bau" can adjust the hormone balance in the plant, which can greatly reduce the size of the apple. The specific measures are as follows:
Focus on underground, promote new roots, balance hormones. The apple root system has three growth peaks every year. It is fertilized in the autumn (April to May) and autumn harvest (September to November). It is diluted with water 1 to 15 kg, combined with fertilization and irrigation. And foliar sprays, mainly to promote the root system and regulate hormone balance. Old trees and weak trees should be used in larger quantities, using "bi-guard" 2 to 3 grams.
Postharvest leaf protection, accumulation of nutrients, and prevention of cold winter. After the fruit is harvested, there are still 30 to 40 days of growth time for the shoots of the shoots. The differentiation of the flower buds continues and the shoots are gradually enriched. At this time, the nutrient produced by the leaves is accumulated in the tree body. After the fruit is harvested, use “Biao†1g watered 15kg plus foliar foliar for foliar spray, combined with autumn fertilization, “Biao†1g watered 15 to 20 kg to irrigate or ditch . "Biao" has the function of enhancing photosynthesis in leaves and preventing premature senescence of leaves. It can also enhance the concentration of cell liquid in fruit trees and increase the resistance of fruit trees to late spring.
In the year of the year, thinning and thinning fruits and small flowers are promoted. In apple management, it is necessary to spend thinning and fruit thinning. In particular, it is necessary to strengthen the management of fertility in the autumn of the next year and prevent it from becoming smaller in the coming year. Through pruning to control or adjust the amount of flowers, to achieve a reasonable percentage of leaf and fruit, so that the tree's nutrient accumulation and fruit consumption to achieve a relatively balanced, thus reducing the size of the phenomenon. The large number of flowers in the big year, the principle of pruning is to ensure the output of the year under the premise that the winter should be properly re-cut, so that the growth results reach a balance and improve the quality of flower buds. With less annual flowers, the main goal of management is to preserve the fruits and preserve the fruits, so that the small year is not small, and no excessive flower buds will be formed in the year. In the apple red period and after the Xiehua flower, using "Biao" 1g watered 15 kg foliar spray, can promote hormone balance, promote fruit enlargement, to achieve the balance of vegetative growth and reproductive growth, so that the size of the apple produced is uniform , Appearance looks good, taste and flavor are good.
