Plum Tree How to Spare Thinning Fruits
Due to the large amount of plum trees and high seed-setting rate, appropriate amounts of thinning and thinning fruits can save tree nutrients, regulate the distribution of nutrients, increase the fruit setting rate, and ensure fruit quality. Sparse flowering is generally carried out in the flowering period. When specific flowering is carried out, the flowers at the base of the branches are removed, and the flowers in the middle and upper part are left. It is better to leave single flowers. The flowers on the preparation branches must be completely neglected, and the flowers in the middle and lower part of the crown should be sparsely populated. To stay longer, the outer and upper layers of flowers should be sparsely left; the auxiliary branches and strong branches should be left with more flowers; the branches and weak branches of flowers should be kept less; on a result branch, two heads should be sparse, leaving the middle to develop normally. Flowers; For the flowers on the bouquet fruit branch, to stay in the middle, sparsely peripheral. The sparse fruit can be carried out 1 to 2 weeks after the flowering period. The yield per plant is determined according to the species, tree age, tree vigor, and fruit size. The fruits, fruits, wounded fruits, deformed fruit, lush fruits and unclean fruits are removed. The fruit shrubs should be taken from the top to the bottom and from the inside to the outside.

â… Product Composition: polydadmac
â…¡ Product Properties
The appearance of this product is colorless to pale yellow viscous liquid. It is soluble in water. It has goodhydrolyticstability and high adaptability to PH value changes. It`s safe and non-toxic. Its freezing point is about -2.8℃, specific gravity is about 1.04/cm3 and decomposition temperature is 280-300℃. It`s polymeride AKD maturing agent of high charge density. Emulsion provides strong cationic component promotive and protective agent and promotes curing effect. This product is added directly into the synthesis process of intermediates or added a certain ratio in emulsion. This product can be added more in the papermaking system with heavier anionic trash, as the pulp potential equilibrium to play a dual role of sizing enhancement and forcing ripening.
III. Quality indicators;
Appearance: colorless to faint yellow thick liquid Solid content: 40±1%
PH value: 4.0~7.0 viscosity (mpa.s, 25℃): 7000-12000
IV. Application:
This product is applied in alkaline sizing system of AKD (Alkyl Ketene Dimer) to restrict largely the hydrolysis and migration aptitude of AKD. [The third generation" AKD is mainly used for the making of multipurpose duplicating paper filled by precipitated calcium carbonate. 60% cationic polymer can adhere to the fiber after the paper containing cationic polymer being reused, by which enhance hydrophobicity of the paper. Added to waste paper deinking agent, its cationic hydrophilic group adheres to ink particles easily, especially for hydrophobic aniline ink. After flotation, the whiteness of pulp increased. This product is also applied as cationic surfactant in pitch control agent for pulping.
