First, choose a good variety
The use of high-quality, high-yield, and strong-resistant hybrid corn seeds: Fodan 7, Yao 8818, Wuguyu 68, Shangdan 2012, Zhaoyang 6, Yunrui 21 and other varieties. Use 1.5-2 kg per acre.
Second, preparation before broadcast
1, fine soil preparation: in the pre-rainy rain as required by the entire model of the land, so that a plough a plow, flat land fine.
2, standardize the theory: According to the requirements of the standard management of the surface and groove out of sowing ditch.
3, planting specifications and density: the use of wide and narrow rows of planting, 1.8 meters composite belt, that is, a wide line of 1.2 meters, a narrow line of 0.6 meters, 0.4 meters from the pond, leaving 2 per pond, density 4000-4200 per acre. Two rows of soybeans were planted in the middle of the width and the spacing was 30 cm.
4, sowing technology: directly after the rain on demand, combined with soil testing formula fertilization, per acre Shi farmyard manure 1000-1500 kg, 15-20 kg of urea, 50 kg of calcium, potassium sulfate 5-8 kg base fertilizer, pull Planting lines, 3-4 grains per pond, consistent in depth and depth, cover soil immediately after sowing, cover fine soil 2-3cm, use phoxim and chlorpyrifos granules to control underground pests, cover with thin film after spraying, and sprinkle rat poison on them. Or use the first cover film after sowing.
三ã€Cultivation management
1, check the missing patch: After emergence, timely view of seedlings, reseeding seedlings.
2, timely rupture of membranes, seedlings: In 2-3 pieces of corn leaves, when the top film timely rupture membrane, membrane rupture and time seedlings, leaving 2 per pond.
3, Qiao Miao Fei
In the 5-7 corn leaves, combined with the management of the tillage, wolfberry, 20 kg per acre ammonium nitrate, when applied from the seedlings 5-10 cm, see seedlings fertilization, seedlings less applied, weak seedlings and more.
4, re-attack panicle fat
During the big corn flare, this period is the end of the vegetative growth stage and it is transferred to the reproductive growth stage. Consumed nutrients account for about 50% of the nutrients in the entire growth period. Combined with large earth, 40 kg of ammonium nitrate per acre is applied to the two ponds. Distance to the middle. Panicle fertilizer ensured that the late growth of the plant was not defertilized and the disease resistance in the middle and late stages of growth was improved, which laid the foundation for high yield.
5, pest control
In the seedling stage, small tigers were used, and 50% phoxim EC was sprayed on the roots of the corn at the watering roots or in the evening (at 6 pm); maize corn borers occurred at the big corn horns, and the distillers' leaves were used (the dosage was 1 kg/mu. Prevention and control; aphids occur during tasseling, and are treated with water sprays against aphid (for various doses of pesticides see instructions)
6. Interlaced
When the corn is just drawn, it can be removed by row or septum to remove the tassels. The whole field is emasculated by half, which is conducive to ventilation and light in the field, saving nutrients and reducing pests, and can increase production by 5-8%. The method of detasseling is: When the tassel is pulled out from the parietal lobe by 1/3 or 1/2. Prior to loose powder, the apices were removed in a row or septum in time. It is best to take the first male or weak plant. The male flower of the insect strain is removed, but the field side line should not be emasculated so as not to affect the pollination. When emasculating, it is not allowed to damage the top leaf, and it is better not to cut off the stems and leaves above the ear, otherwise it will reduce the yield.
7. Artificially assisted pollination
In the event of strong winds during the flowering season of corn, or when the weather is cloudy for more than 2 days, or when the rain is high, artificial pollination may be carried out. Pollination should be carried out on sunny days after morning dew (9-11 o'clock). The collected fresh pollen is removed from the glume and then given to the filaments of the female ear.
Fourth, timely harvest
The black layer of the grain can be harvested, and the leaves hanged to prevent the damage of the ear.
[CARRY BAG DESIGN]The unique folding design rollaot walker with seat allows you to adjust the width. It permits you to navigate narrow spaces. Detachable front wheels and rear wheels,it comes with a carry bag allowing you put your rollator in the travel case, a car trunk or cabinet.
[HUGE WHEELS] The 10 inch front wheels walker provides better stability and security when you rolling on the rollator uneven surfaces. Compared with rollators with 8 inch wheels, our roller can better accommodate rough or soft ground such as: lawn, sand, forest, etc. The two-size wheel system is much easier to push over any surface, including floors and carpets.
[FAST BRAKING] Tntiskid tread pattern on wheels increase a stronger grip to prevent the slipping between wheels and road.The gears control the braking more effectively.Also the ergonomic handles are part of an easy-to-use braking system that can be locked when you do not want the walker to roll. [1-Click Button" allows you easily to adjust the height of handles.
[ADJUSTABLE HEIGHT]Allows you to customize your suitable height to avoid hunching over a walker and won`t feel pains if you walk for a long time.
