Strengthening wheat management to ensure safe winter

This year, the city's autumn sowing wheat area has reached more than 900,000 mu, a slight increase from last year. The quality of soil preparation in this year has improved, the phenomenon of dew-seeding wheat has decreased, the proportion of seedlings and ridges has declined, and the emergence of seedlings has been good. At present, the wheat population is reasonable and the individuals are robust. It is one of the better years in recent years and lays a good foundation for the cultivation of pre-winter strong seedlings.

At present, sufficient accumulated temperature provides guarantee for the growth of wheat; but in October, the sunshine duration was 164.3 hours, which was less than 30% of the annual average; only two obvious rainfall processes occurred from sowing to emergence. The total rainfall was only 9.3 millimeters, less than last year. 37.9 mm, less hours of sunshine and less rainfall, are detrimental to wheat growth. On October 25th, the Municipal Agricultural Technology Promotion Station investigated the soil moisture content at the monitoring sites in the city, and the land with insufficient soil moisture content (relative water content below 65%) accounted for 45%. According to 82 monitoring points, the average basic seedlings were 352,000/mu, the total stem number at the end of October was 509,000/mu, the main stem leaf age was 3.3, and the single-planting tiller was 0.7. With the postponement of the sowing date, the basic seedlings will increase accordingly. Except for some of the basic seedlings in the period from September 26 to September 30, the basic seedlings in other sowing periods will be more reasonable. The total number of stems at the end of October can basically meet the next year's succession. The request. And dark green leaves, there is no defermenting phenomenon. In general, this year's wheat population is reasonable and individuals are strong, which is conducive to the formation of pre-winter strong seedlings. Therefore, we must strengthen pre-winter management and pour well overwintering water.

First, some plots have poor lyrical condition, and they should seize the time to water the first seedling stage to ensure the normal growth and delivery of wheat. Second, the plots that are covered with headwaters should be artificially broken and placed in a timely manner. Seedlings; Third, the poor quality of field sowing, wheat seedlings serious overhead, there are plots of yellow seedlings of the plot, should be poured as soon as possible seedling water, in order to practise the soil, reduce the dramatic changes in ground temperature damage to seedlings; four is planted before the 25th, and The plots with large amount of the following species, slender leaves, missing pods and premature ridge closure can be suppressed once in recent days to control excessive growth. Fifthly, the heavy plots of golden worms or locusts should be timely. Take root and spray methods to prevent further development of pests.

It is estimated that the daily average temperature of this year will pass through the late days of late November when the day of 0°C (the date when winter wheat ceases to grow) is stable. Timely, adequate, and generally well-watered frozen water are the most important measures for keeping the seedlings safely in winter. Frozen water should be poured at a daily average temperature of 3°C-5°C (late November). All localities should reasonably arrange the watering time according to the rotation period. When the temperature drops to 0°C, irrigation should be stopped. Sprinkler irrigation can not be less than 8 hours, irrigation canal irrigation 50 acres per mu. To prevent the use of seedling water in place of frozen water, even in the late October to early November when the water poured over the seedling stage, but also poured enough cold water in late November. The frozen water time and amount of water are well-understood, and the surface will produce a clear freeze-thaw process. The tiller section will be overwintering in the frozen soil, and the surface soil will be finely crushed, free of waste, and free of cracks. Immediately after the pouring of frozen water, suppress it.

Dry Strength Agent

I. Introduction
Papermaking dry strengthen agent is our company`s new and self-developed products that using imported raw materials. Its mechanism of action is: dry strength agent use polymer mesh structure to increase hydrogen bonding number in the mutual area of fiber to fiber. Dry strength agents in the combination area of long-chain polymers can be deformed, thus increasing the bond toughness. It could improve paper strength by the bridging ability formed by chemical function to make fibers and fibers have "implicated"

II. Technical indicators

III. Function

The dry strength agent is not only a good enhancement, but it also has a higher enhancement effect in waste papers with more fine fiber filler. The use of our dry strength agent can improve paper quality, and it also significantly increase production efficiency, reduce costs and increase economic efficiency.

IV. Method of Application and Notes

1. When diluted with clean water, the dilution multiples of our product is generally about 15 to 30 times. After the product was stirred sufficiently, add uniformly to the slurry in an amount of 5 ~ 10 kg / ton.

2. Adding position that selected could have a full contact with the slurry. Generally choose ingredients pool, high box or import pump.

3. Use a plastic or stainless steel as the material for products storage, dilution tank, piping etc.. Iron-based material will produce corrosion and thickening phenomenon will occur.

4. Do not mix with Other Chemicals.

V. Packing

1000 kg barrels, or according to user requirements.
