How does peach apply bio-organic fertilizer? The roots of peach trees are shallow, and the absorption roots are mainly distributed in 10-30 cm, but the root system is more developed, with more lateral roots and fibrous roots, and the ability to absorb nutrients is stronger. Peach tree fertilization should be applied properly, or combined with deep application and shallow application. Peach's fertilization period is: base fertilizer, promote flower fertilization, sit fruit fertilizer, fruit enlargement fertilizer. The fertilizer application amount of peach trees should be determined flexibly according to the soil fertility, age, variety, yield, and climate factors. In the orchards with low soil fertility, high tree age, and high yield, the amount of fertilization is higher; the fertilization of orchards with high soil fertility, low age, and low yield is appropriately reduced. The best time for peach basal is to be applied after the fruit is harvested. If it cannot be applied timely, it can also be applied about one month before the peach defoliation. Plant Shennong Brand Bio-organic Fertilizer 5~8kg. Do not rely too much on the tree when fertilizing. Combine it with soil when fertilizing. Peach trees with many soil moisture content, heavy soil texture, large tree age, and weak tree vigor can increase the amount of fertilizer when applied; otherwise, the amount should be reduced. The peach top dressing is applied three times. The first time was to promote flowering before flowering in early spring. The application of Shennong brand bio-organic fertilizer was 2 to 3 kg and 100 g of urea was applied. If the growth of the tree is stronger and there is no shortage of fertilizer, the fertilizer may not be applied or reduced. The second time was the fruit-fertilizer after flowering until the fruit nucleus sclerosis. The Shennong brand organic bio-fertilizer was 3 to 5 kilograms and 150 grams of urea was applied to improve the fruit setting rate, improve the nutrition of the tree, and promote the rapid growth of the fruit. . The third time is fruit enlargement and fertilizer. Applying 3~5 kg of bio-organic fertilizer and 200 g of urea to promote rapid fruit growth and promote flower bud differentiation will be of great significance for the next year's production.
Imported Premium White Carbon Black
Silica black is the general name of white powder X-ray amorphous silica and silicate products, mainly refers to precipitated silicon dioxide, gas phase silicon dioxide and ultra-fine silicon dioxide gel, including powder synthesis of aluminum silicate and calcium silicate, etc. Silica is porous and its composition can be expressed as SiO2·nH2O, where nH2O is in the form of surface hydroxyl groups. Soluble in caustic soda and hydrofluoric acid, insoluble in water, solvents and acids (except hydrofluoric acid). High temperature resistance, non-combustion, tasteless, odorless, with good electrical insulation.
