1 avoid surface application. Ammonium bicarbonate applied to surface soil fertility to the loss of 25% to 30%

1 avoid surface application. Ammonium bicarbonate applied to surface soil fertility to the loss of 25% to 30%. According to the determination, when the air temperature is 29 DEG C when applied to the soil surface of ammonium bicarbonate within 12 hours of nitrogen losses of 8.9% and 8 to 10 cm deep fertilizing soil cover, less than 1% loss within 12 hours. The general and deep application of ammonium bicarbonate soil, than the soil surface application improve fertilizer utilization rate of more than 20%.
2 avoid dry soil application. The soil is dry, even deep application coverage can not be dissolved and ammonium adsorbed by soil and crop absorption and utilization. Only in the soil with certain water content under the condition of application of ammonium bicarbonate to dissolved timely, reduce the loss.
3 avoid making a kind of fertilizer. The ammonia produced in the decomposition process has a strong killing effect on seed embryo and seed bud, which seriously affects the germination and emergence of seeds. Therefore. Not dressing seed.
4 avoid contact with crop stems and leaves. Using ammonium bicarbonate as top dressing, a little carelessness will hurt the crop stem leaf smoked, light foot leaves red, yellow, heavy like fire. For the best rice ball made of topdressing fertilizer, and deep application; if the applicator should mix 2 ~ 3 times of the dry fine soil, in cloudy or sunny after 4 p.m., Tian face of the need to maintain 3 ~ 5 cm layer, side edge scattering cultivator. For dry land crop fertilizer, should first open ditch, hole, and then add water pouring or mixed with soil applied ditch, hole in the side of the side cover soil fertilizer.

5 avoid and alkaline fertilizer mix. Ammonium bicarbonate and plant ash, lime kiln, ash, calcium magnesium phosphate and other alkaline substances mixed, will immediately produce a chemical reaction, ran out of large ammonia caused by nitrogen loss, reduce fertilizer, so it should be separated from the application, before and after every 2 to 3 days.
6 bogey and superphosphate mixed after overnight application. The mixed application of ammonium bicarbonate and calcium superphosphate, although separately has good effect, but should be immediately under application after mixing, should not be mixed after a long time, not overnight. This is because the hygroscopic superphosphate strong, will make compost into slurry or caking, unfavorable application, and ammonium bicarbonate is volatile, long easy loss.

This cheap nitrogen fertilizer is better than urea

Ammonium hydrogen carbonate or bicarbonate, is a commonly used nitrogen fertilizer. Many farmers believe that the urea fertilizer ratio of ammonium bicarbonate is high, so at the time of fertilization choice rather than urea ammonium bicarbonate, in fact, in the winter or early spring cold season, using methods, both for potato, rape, wheat, vegetables and fruit trees, basal manure fertilizer or fertilizer, application of ammonium bicarbonate is better than urea. But there are many taboos in the process need to pay attention to the use of ammonium bicarbonate, today will try to understand.

sulphamic acid

Application of ammonium bicarbonate, has many advantages in production.
Nitrogen loss is small. The speed was positively correlated with the temperature of the high temperature decomposition of ammonium bicarbonate, the decomposition is faster, the greater the loss. At temperatures below 20 DEG C, less volatile, applied into the soil in a certain range of depth, the ammonium nitrogen is relatively stable, and is not easy to be adsorbed by soil colloid, with water loss, good preservation of nutrients for crops in the whole growth period. Urea under low temperature conditions, applied in the soil after the molecule dissolved in the soil solution, can not be adsorbed to soil particles, easily by water leaching with water movement, with the water loss caused by nitrogen.

Thiourea

The two is of high efficiency and fast. Ammonium bicarbonate large solubility even at 5 DEG C, fertilizer can also be absorbed by crops, so in the winter cold season, the application of ammonium bicarbonate can quickly be absorbed by crops. When the soil temperature is at 10 DEG C, after applying urea transformation requires 7 to 10 days, with the temperature decrease, urea transformation needs more time, so the low temperature season effect is far less than urea ammonium bicarbonate.
Three is the use of security. Does not contain ammonium bicarbonate ingredients, no adverse effects on soil after application. The release of carbon dioxide and ammonium bicarbonate decomposition also improve crop photosynthesis intensity, improve crop yield level.
Application of ammonium bicarbonate, to give full play to the effect, there are 6 points need to pay attention to taboo.

Pesticide residue limits in China have reached 4140

The reporter learned from the Ministry of agriculture, the day before, the national food safety standards of food “pesticide MRLs” formally promulgated and implemented 2016 edition. The new national standard of pesticide residues in the standard, quantity and coverage of all have a great breakthrough, provides 433 kinds of pesticides in the 13 categories of agricultural products in 4140 residues, than the 2014 version 490, covering the major agricultural products in China has approved the use of pesticides and the daily consumption of residents.

Magnesium sulphate

The new version of the release of the pesticide residue limits has three main characteristics: one is made of fenamiphos and other 24 kinds of banned and severely restricted pesticides 184 pesticide maximum residue limits for the illegal use of the restriction of pesticide regulation provides decision basis. Two is in accordance with international practice, there is no dietary risk of the 33 pesticides, the exemption of the maximum residue limits in food standards, and enhance the scientific standards of pesticide residues in food. Three is in addition to the standards involved in the limited recommended matching detection methods, but also simultaneously released 106 pesticide residue detection methods national standards.

Sulfamic acid

It is reported that China is now released in food pesticide residue limits are based on field test data, dietary consumption data, pesticide toxicology of domestic agricultural market data and monitoring data of China pesticide residues, through the risk assessment after the development of the.

In December 22nd, Guangxi Shintede anhydrous alcohol device to maintain production

In December 22nd, Guangxi Shintede anhydrous alcohol device to maintain production, Nissan 100 tons level. The ethanol factory price 5850 yuan / ton tax, you can talk about. Guangxi Siyuan molasses ethanol production Nongken device stability, load increased, Nissan about 290 tons nearby. At the 95% general level of molasses alcohol factory price 5150 yuan / ton tax, a firm can talk. Four alcohol plant in Henan Huixian area maintained production. At present, 95% ordinary alcohol valuation of 4800 yuan / ton tax, high-end price 4850 yuan / ton excluding tax. The alcohol factory recently to go smoothly, basically no inventory. Shandong floating spring biotechnology to produce anhydrous alcohol device is stable, the factory retail price 5750 yuan / ton tax, you can talk about the recent go smoothly. Shandong floating to the spring biotechnology production of cassava ethanol device stability, new plant also maintains the total production, Nissan thousand tons. 95% ordinary retail alcohol factory price including tax 5150 yuan / ton, high alcohol retail price 5300 yuan / ton tax, alcohol retail price 5750 yuan / ton tax.

Overall, in late December, East China wine enterprises to take the goods, inventory is still low, Shandong wine enterprises to go smoothly, the downstream receiving ethyl trading market is stable, good, Jilin area inside the purchase and sale of a good atmosphere, the downstream demand procurement, Southern China area may temporarily take the goods market, stable operation. Is expected in the short term domestic ethanol market will be strong stability.

A recent ethanol market steady potential in the short term will be strong dimensional stability

stability is recent ethanol market trend. The ethanol market trading atmosphere is acceptable, but the factory operating rate is not high, the limited supply of goods on the market, many manufacturers no inventory status. Downstream demand procurement, purchasing enthusiasm.

In December 21st the commodity index was 77.33 ethanol, and the same day, the highest point in period 100.85 (2012-05-24) fell by 23.32%, compared to 07 in 2016 25, the lowest point of 71.20 months rose 8.61%. (Note: the cycle refers to 2012-03-01 so far)
