Physiological physiological fruiting peach trees, the first fall is mostly poor pollination and fertilization, the latter is the result of tree nutrient reserve has been exhausted, while the new hair is insufficient, in a young condition, lack of photosynthetic products, organic nutrition, for Not on the demand for young fruit development, resulting in a large number of fruit drop.
Peach trees have many causes of fruit drop. The daytime temperature is higher than 33°C, and the nighttime temperature is lower than 10°C; the trees are left with too much light and the light deteriorates; the adjacent fruits collide with each other; the water and fertilizer management is disordered and the growth of new shoots is taken away. The nutrients needed for fruit growth can cause fruit drop. The effective ways to prevent peach fruit falling are:
First, from the high ridge, cover film
When cultivating peach trees, the mulch can increase the moisture content of the soil, increase the early emergence of new roots of the peach tree, increase the activity and absorption capacity of the root system, and significantly reduce the fruit drop.
Second, fertilizer and water management
Spring base fertilizer should not be too late to avoid large-scale application of nitrogen alone, should be combined with phosphorus and potash fertilizer; and should focus on the supply of fertilizer before the hard core amount of water, hard core should not be poured after the beginning of flooding.
Third, spraying during the expansion
To improve the low temperature resistance of peach trees and increase hair roots can effectively reduce the occurrence of fruit drop.
Fourth, science pruning
Pruning can not be too heavy for Wang Chang peach tree, reasonable sparse canopy, thinning off the dense branches, timely cutting control of leggy branches, improve the ventilation and light conditions of the crown, increase light, increase the blade assimilation function, appropriate early fruit thinning, Adjust nutrition distribution.
