Gold in early autumn, silver in late autumn, copper in fallen leaves, firewood in spring.
This year, due to the heavy rainfall experienced in September for more than 50 years, the rainfall was close to 900 mm, more than the 825 mm rainfall in 1956, which delayed the best time for the application of the base fertilizer in autumn, and the soil was too humid, the rain drove away the oxygen in the soil, a large number of capillaries died, the soil germs flooded, resulting in early fall of leaves, affecting the differentiation of flower buds, affecting the accumulation of more storage nutrients in the tree, so it is more important to apply the base fertilizer this autumn!
In the same plot, spend the same money, use the same fertilizer, due to the different time of autumn application of the base fertilizer, the fertilizer absorption and utilization rate varies greatly.
The frost has passed, with the decrease of temperature, the leaf function is also reduced, and it is more important to apply the base fertilizer in autumn!
Due to heavy rainfall, the early autumn application of gold has been delayed, but the effect of silver application in late autumn is more important.
Due to the special year of heavy rainfall this year, the application of base fertilizer this autumn should appropriately increase the amount of bio-organic bacterial fertilizer → the mu application of 100 million bacterial treasures, improve the soil, increase soil permeability, repair capillary roots, improve the absorption and utilization rate of fertilizer, increase the accumulation of stored nutrients, promote the differentiation and fullness of flower buds, and enhance the safe overwintering of the tree body.
For orchards with serious physiological diseases, it is necessary to pay attention to the amount of medium and trace element fertilizer → silicon calcium and magnesium fertilizer.
For the autumn application of base fertilizer in orchards, it is necessary to base on long-term sustained release, adhere to bio-organic, full nutrient balance fertilization. Fruit trees eat 17 kinds of elements, in addition to the hydrocarbons do not need to be deliberately supplemented, the remaining 14 kinds of elements, must be combined reasonably, so that the fruit trees are full of food and drink enough, and enhancing the tree potential is fundamental.
Scheme: Billion fungus treasure + long-acting fertilizer or slow-release fertilizer or gold quaternion + silicon calcium and magnesium + deep three feet of nourishment easy to apply.
All fruit farmers who rely on fruit trees to support their families should recommend that the autumn fertilization end and immediately do three tasks:
(1) Clear the garden in autumn, eliminate the overwintering diseases and insect pests, reduce the base of diseases and insect pests in the coming year, and add 2% petrochemical urea, and spray 3 to 5% petrochemical urea separately at 7 days intervals, supplement nitrogen nutrition, and increase tree storage nutrients.
Scheme: 5000x star + 1000x Longlile or 800x Chlorpyrifos + 6000x Silk + 2% petrochemical urea.
Above and below ground, washed in the garden. Autumn Qingyuan is more important than Spring Qingyuan!
(2) This year's preview is frozen, Mengli 28 + star label coating rod, prevention and control of rot and improve the storage of nutrients in the tree, to prevent frost damage and safe overwintering is particularly important.
Scheme: a bucket of Mengli 28 + a bucket of water + 2 bottles of star marks + 1 bottle of silk, with a brush to apply the main pole and the main branch branches or spray with a stick sprayer.
(3) Remove fallen leaves. Due to the serious defoliation of brown spot disease this year, the leaves are removed and buried deeply after the leaves are fallen, which reduces the overwintering base of brown spot disease and prevents the outbreak of brown spot disease again next year due to the excessive base of the previous year.
Fruit farmers who hope to sell out of fruit, seize the time to apply the base fertilizer in the autumn, no matter how late it is than the spring application!
After fertilizing, do three things conscientiously!
