Wheat wants to do a good job of these things

Wheat from flowering and fertilization to grain maturation generally takes 30-40 days, which is the last critical period for the formation of wheat yield. It is the main period for accumulating storage nutrients. 80%-90% of carbohydrates in grains are photosynthesis after wheat flowering. The 90% of the nitrogen in the grains is transferred from the stems and leaves to the grains. Therefore, it is very important to protect roots and protect leaves, delay leaf senescence, promote grain filling, increase grain weight, increase yield, and achieve high and stable yields. necessary. Pay attention to the following tasks:

Water slurry, chase slurry fertilizer

Filling stage is the final stage of wheat grain yield and has an important impact on wheat yield. This period has more demand for water, which can be combined with irrigation, topdressing urea 3-5 kg ​​per mu. Whether irrigation and topdressing during grain filling should also be determined based on a variety of factors. If there is a rainfall with a rainfall of 20 mm or more during the grain filling period, no slurry can be poured. If the precipitation during the grain filling period is small, slurry can be poured. Groups that are large, overgrowth, and lands that are at risk of lodging do not pour slurry water and do not top-dress.

Spray fertilizer, anti-dry hot wind

In the late growth stage of wheat, the absorption capacity of the roots is weakened, and foliar dressing can prolong the functional period of wheat leaves, increase photosynthesis, prevent disease and lodging, and mitigate the damage of dry hot wind. Use 0.4% potassium dihydrogen phosphate plus 2%~3% urea mixture, or add other ecological active fertilizer for foliar spray. Interval sprayed once every 7 days to increase the grain weight and optimize the quality.

Pest control

The filling period of wheat is a peak period for the occurrence of various pests and diseases, and it is also a critical period for increasing the 1000-grain weight of wheat. In this period, the main control subjects were wheat stubble and wheat powdery mildew, rust, scab, and leaf blight. Grasp the key period of disease prevention and pest control in early April and early May. For wheat head blight, we must adhere to the “active attack” and unswervingly implement the prevention and control measures. For locusts, we must effectively implement the “moving at the gate and controlling the pressure”. After ", the following formulations can be used for pest control:

1. 70% imidacloprid wettable powder 3 ~ 5g + 4.5% beta-cypermethrin EC 80ml + 45% Benzochlor 25g +98% Potassium dihydrogen phosphate 100g + 0.01% Brassinolide 8ml .

2, with 50% nitenpyrazine wettable powder 8 ~ 10g + 4.5% beta-cypermethrin EC 80ml + 25% benziconazole EC 30mL +98% potassium dihydrogen phosphate 100g + 0.01% brassin Lactone 8 ml.

3. Use 2.5% bifenthrin water emulsion 80 ml + 48% cyanogen tebuconazole suspension 10 ml + 98% potassium dihydrogen phosphate 100 g.

The above formulas are mainly used to control aphids and powdery mildews, as well as to combat midge, scab, rust, leaf blight, and dry hot wind. In addition, grassy weeds should also be removed in a timely manner.
