In order to increase the use of phosphate fertilizer for fruit trees in June
First, the growth characteristics of June: 1. It is the second peak of fruit tree root growth. The root growth of this fruit tree is mainly to supply fruit growth on the tree and lay the foundation for promoting the second enlargement of the fruit. Roots are underdeveloped and have poor absorptive capacity. Combined with the effect of phosphorus, application of high-phosphorus planting hormone can promote the rapid growth and development of the root system. 2. It is the peak of flower bud differentiation in fruit trees. Flower bud differentiation is divided into three periods, namely physiological differentiation, morphological differentiation and sexual organ formation. The 5th and 6th are the peaks of physiological differentiation of flower buds. This period is a transformation process from vegetative growth to reproductive growth of fruit trees, and it is also a process from quantitative change to qualitative change, which will determine the quality of flower buds. 3. It is the nutritional critical period of fruit trees throughout the year. In this period, although the consumption is not large, it is very urgently needed. It is precisely because the green and the yellow are not connected. Therefore, scientists call this period the nutrition "critical period" of fruit trees. In the early period, budding, long rooting, branching, leaf spreading, flowering and fruit setting of fruit trees have exhausted the storage nutrients of the fruit trees. The leaves began to use the photosynthetic source to continuously produce nutrients, and then the fruit trees will soon enter the fruit's rapid expansion. In this period, nutritional supplements to fruit trees must be timely and sufficient. 4. It is the transfer period of endogenous hormones in fruit trees. In this period, the first enlargement of the fruit is completed. The growth of the tree grows and transfers to the underside of the tree. The growth of the branches and leaves is transferred to the root. The sugar content of the fruit is transferred to the flower bud and the vegetative growth shifts to the reproductive growth. In this period, the nutrients of the fruit tree determine the size of the fullness of the fruit seed kernels, and the kernels are not hard and full, and no matter what measures are taken in the later period, the fruits will not be large. 5. It is the critical period for fruit trees to prevent pests and diseases. During this period, the climate in the Eucalyptus area of ​​fruit trees is fickle, changing, with hail, strong winds, drought, thunderstorms, worms and birds emerging, malnutrition, and fruit trees with debilitating trees are most prone to various rot diseases. During this time, the fruitful work of the fruit grower is over, and the fruit is over. It is followed by twisting, pulling, watering, fertilizing, spraying medicine, bagging, and cutting grass. Second, the role of phosphorus Phosphorus controls the metabolism of carbohydrates and the outward transport of sugar in fruit trees. It can improve the ability of drought resistance, cold resistance, disease resistance, stress resistance and lodging resistance of fruit trees, in particular, it can promote the development of roots and flower bud differentiation of fruit trees, and thus phosphorus. It is called the "energy element of plants." In early May and early June, it is the critical period for determining the size of the fruits of the year, establishing the fruit quality of the next year, eradicating the size of the year, and protecting the leaves and roots. It is also the prevention of rot diseases and various pests and diseases. Very period.
