Top dressing high-yield soybean yields

The summer sowing period coincided with the “three summers” busy season. The under-employed households were planted under the condition of no fertilization, and the nutrients needed for soybeans depended on the residual nutrient in the soil of the former crop and during the growth of soybeans. top dressing. Therefore, top dressing plays an important role in increasing soybean yield. The top dressing techniques are as follows:
Early application of Miao soybean seedlings in the seedling stage is in the formation stage, there is no nitrogen-fixing ability, if the nitrogen nutrition can not keep up, it will affect strong seedlings early onset. Early recovery of Miaofei can promote root and leaf growth. Usually when the first compound leaf is unfolded, 4-6 kg of urea is recovered per mu. Appropriate amount of phosphate fertilizer at seedling stage is conducive to promoting the formation and development of soybean root nodules.
Qiao Shi Huafei soybean flowering period is to absorb the peak period of fertilizer, the early flowering period can be applied after the appropriate amount of nitrogen fertilizer, can reduce the loss of calyx, mu production increase 15-20%. Generally, 5-8 kilograms of urea are used per acre. A hole is applied at a distance of 5-7 cm from the root of soybean, and the soil is applied after the application. If the soil is fertile and the plants grow robust, either less or no nitrogen fertilizer. When phosphorus is insufficient in basal fertilizer, 7-10 kg of superphosphate can be supplemented per acre in this period.
After spraying granulated soybeans into the scab, the nitrogen fixation ability and root vigor of the rhizobia gradually declined, and the ability of sucking fertilizers was weakened. In this period, foliar spray fertilizer should be used to supplement the nutrients and reduce flowering and falling. In general, use 0.3% potassium dihydrogen phosphate solution per acre 50 kilograms, after 4 pm to evenly spray on the front and back of the blade, and even spray 2-3 times. If there is a phenomenon of denitrification, 0.5 kg of urea can be mixed and sprayed per acre.

With the constant improvement of economic level, people` requirements on the quality of paper are increasing high. A great number of paper products must have excellent resistance to fracture under moist state, in other words, must have a certain degree of wet strength. While the traditional papermaking wet strength agents are urea resin and melamino-formaldehyde, both belonging to formaldehyde resin with intense pungent smell and certain toxicity, and can be used in acid condition to acquire the wet strength. However the whiteness will descend a lot and the paper will be weak after the finished paper acquiring the wet strength. Polyamide polyamine epichlorohydrin resin (PAE) is water soluble, cationoid and thermosetting resin. This product is a non-formaldehyde polymer, non-toxic and tasteless, with a wide range of PH value and suitable for acid, neutral or slightly alkaline papermaking conditions, as well as the acid condition. Wet strength effect is better than the urea-formaldehyde resins and melamine formaldehyde resin. PAE resin, which is an excellent Wet Strength Agent, develops fast in recent years with China`s paper industry development.

The high performance papermaking wet strength agent (PAE) that we produced has been widely used in a great amount of domestic factories and the finished paper products` wet strength index has surpass the similar products in domestic and foreign counties.

1. Performance Indicators

2. Application

PAE active ingredient is polyamide epichlorohydrin thermosetting resins that can be used as below:

1. Paper products with the need for drying or wiping water, such as: napkins, wet tissue paper, facial tissue, paper napkins, kitchen towels, wiping window paper, industrial wipes, lens wiping paper, cosmetic paper etc.;

2. Outdoor paper: such as kraft paper, packing paper, outdoor poster paper, construction paper, sack paper, map paper, germinating paper, fruit bag paper;

3. Wet wrapping materials: such as paper cups paper, meat paper, wrapping paper and boxes for fruits and vegetables, frozen and refined food packaging paper, pressure sensitive copy paper, filter paper, leaching processing paper and tea bag paper;

4. Paper soaked in water: as photographic raw paper. Instead of disposable textile products, such as hospital bed sheets, toilet paper and other disposable hospital garb.

Other issues such as cigarette paper,  paper used for invoices.

PAE, as wet strength agent excellent efficiency (PAE), has been widely accepted by the papermaking industry

5. Storage Condition

Storage: Avoid direct sunlight, prohibiting contact with concentrated acids. Storage temperature is 0 ~ 35 ℃and the product can be stored for up to 3 months under 5 ~ 35 ℃.

4.Package and Transportation Safety

Package: 200 kg polyethylene barrels or 1000 kg IBC barrels.

Transportation: The product is non-flammable, non-explosive and low corrosive and non-dangerous. It can use plastic buckets as containers on railways, highways, aviation, marine to achieve the purpose of the safe transport, and if the leaking occurs during transportation, you can simply rinse on the spot.
