One, Before Maize Seedling Before Seedling
(1) The plots where there are no weeds in the field can be treated in a closed manner, commonly used pharmaceuticals: 40% isopropyl straw 250-300 g/mu; 40% Baba 200-250 g/mu; 40% Dingyuan 200- 250 g/mu; 52% isopropylgrass 200-250 g/mu; 60% isopropylgrass 180-230 g/mu; 40% methyl bismuth 200-250 g/mu.
(2) After the wheat is harvested, the fields with more annual weeds in the field are mixed and used as a “killerâ€: 40% isopropylate 200-250 g + 20% paraquat 150-200 g/mu ; 52% Propofol 150-200g + 20% paraquat 150-200g/mu.
(3) After wheat is harvested, the fields with more perennial weeds in the field are mixed and used to carry out “one killâ€: 40% isopropylate 200-250 g +41% glyphosate isopropylamine salt 250- 300 g/mu; 52% isopropylate 150-200 g +41% glyphosate isopropylamine salt 250-300 g/mu.
Second, the corn growth period
(1) Corn 1-3 leaf stage weeds before unearthing to weeds at the 1-2 leaf stage, commonly used pharmaceuticals: 40% yufeng (isopropanol) 250-300 ml/mu; 40% glutinous Grasshoppers) 250-300 ml/mu; 52% of Xiyangyang (Isoprocatel) 200-250 ml/mu; 60% of Yujia (isopropanol) 180-230 ml/mu.
(2) Maize 3-5 leaf stage is an important period for controlling weeds in corn field. If weeds are not controlled timely, it will directly affect the growth and yield of corn. Corn 3-5 leaf stage, grass weeds 2-5 leaves, broadleaf weeds 3-5 cm high. Common medicaments: 4% Nicosulfuron Suspension 100-120ml/Mu; 40% Jinyufeng (Nicosulfuron) Suspension 100-120ml/Mu; 53% Jade Sweet (Nicotine-Takijin) 90- 105 g/mu. (3) In the 3-4 leaf stage of maize, there are more plots in the field. Commonly-used pharmaceuticals: 40% happy event and more (smoke sore to Tianjin) 80-100 ml +56% 50g/mu mutric tetrachlorate; 4% Nicosulfuron 100ml/mu +56% methyl tetrachlorine 50-60 g/mu; 56% dimethyl sodium tetrachlorate 60-80 g/mu; 48% eucalyptus pine 150-200 ml/mu; 4% Nicosulfuron 120-150 ml/mu.
(4) There are more plots of weeds in the 5-6 leaf stage of corn, and 40% of the happy events can be selected (120 to 150 ml/mu for haze and desflurence); 120 to 150 ml/kg for 40% Jinyufeng (Nicosulfuron). Mu; 40% fate (Sulfomito-Tazin) 250-300 ml/mu; 40% Happiness (halogenated torazine) 80-100 ml + 56% dimethyl tetrachlorosulphate 50-60 g/mu; 40% Fate (sulfamitazine) 100-150 ml + 40% happy event more than 80-100 ml / mu.
(5) Maize 5-7 leaf stage, with lots of weeds such as Cyperus rotundus, field bindweed, peony, and grey vegetable, can be applied with 56% dimethyltetrachloro-sodium salt soluble powder 80-100 g/mu; 48 % Prunella 200-250 ml/mu; 40% Happiness (halogenated torazine) 80-100 ml + 56% dimethyl tetrachloro sodium 50-60 g/mu. (6) After the 8-10 leaves (80 cm in height) of the corn, more weeds will be plotted, and 20% paraquat aqueous solution 150-200 ml/mu will be sprayed between the rows. If the field weeds are sparse, add a close herbicide, such as 40% isopropylate 150-200 ml + 20% paraquat 200 ml/mu. Http://
Specifications
These urine reagent strips are available for manual reading or for use with analyzers. The manual urine reagent strips ensure easy visual reading and give a complete solution for urinalysis. There are various configurations available to suit different needs. New parameters are under development. The urine reagent strips for use with analyzers have a unique check block on every strip and have a much higher reliability with an ascorbic acid parameter.
