Spring came, the ground was open, wheat awakened from hibernation, and the green color in the wheat field increased. At this time, many peasant friends would ask: My wheat needs no fertilization, what kind of fertilizer is good, how much fertilizer is appropriate, and my answer is: It depends on seedling fertilization.
From the perspective of wheat physiology, from the stage of turning green to getting up, wheat plants continue to give birth, leaves and hair roots, and begin to differentiate into young spikes. This is to consolidate pre-winter strong seedlings, strive for weak seedlings, strong seedlings, and suppression of vigorous seedling growth. The most favorable period. Therefore, according to different types of wheat fields, it is necessary to adopt different fertilizer measures. See seedling fertilization can be summed up in three words: insurance, promotion, control.
During the past winter, when they had passed the winter, they had already reached the “6-leaf-one-heart†four-to-five-year-old wheat field with a total acre of 800,000 kilos, a robust plant, normal leaf color, and no yellowing. Fertilize and water to prevent overgrowth and consume too much nutrients, which is not conducive to later high yield. In such wheat fields, measures such as ploughing, weeding, and pest control should be adopted to ensure effective tillering and safe growth for the past years, which will help increase the rate of spikes in wheat and lay a good foundation for the high yield of wheat in the later period. This kind of wheat field is mainly based on "preservation". Wait until the jointing period of wheat, and then fertilize and water, this is called N-backward fertilization method, which is beneficial to the high yield of wheat.
Promote late years of planting late, poor fertility conditions, lack of base fertilizer wheat; short winter wheat seedlings, little tiller; turn green, weak plants, leaves yellow, total wheat stems less than 400,000 in three types of wheat fields; or Straw returned to the field without pouring over the winter water, the soil is loose and breathable, the water evaporates strongly, the soil is arid, and the wheat seedlings appear hanging and rooting phenomenon. In a similar manner to the above, it is necessary to pour the green water in time and apply the green manure.
It is very important to choose fertilizers for roads for this type of seedlings. First, do not use organic fertilizers. As the saying goes: ring fertilizer land, chemical fertilizer prompt seedlings. Due to the low temperature in early spring, the farmyard manure is slowly decomposed and cannot meet the needs of wheat for nutrients. Second, it is necessary to apply quick-acting chemical fertilizers with rapid fertilizer efficiency and timely supply of wheat for growth and development. Each mus of urea can be used with 10-15 kilograms of urea and poured back to Qingshui. On this basis, Lu Hui's rejuvenated dew-side fertilizer (30 ml/bag) can be used again to promote new roots, cold resistance, drought resistance, and disease resistance, which will help turn weak seedlings into strong seedlings. Third, when fertilizing, we should also pay attention to the weak seedlings in some high-yield fields, and we must provide some eccentric fertilizer to make their growth consistent, which is beneficial to increase wheat yield.
The planting was too early and the planting capacity was too large. The flourishing wheat of the previous year had emerged. Due to the premature closure of the ridges, the leaves were scattered and the leaves were too thin and too thin. After returning green, they were mainly controlled by Measure, multi-stroke, try not to water, look at seedlings, but also pay close attention to whether there is frost damage, if there is frost damage, should take appropriate measures.
As the saying goes: “There is no gluten in wheatâ€. If a flourishing wheat seedling needs to be repressed, squatted, or chemically controlled prior to jointing, it can be done with 200 ppm Paclobutrazol or 0.15% to 0.3% Chlorothorax , 30 ~ 40Kg per acre of water spray, control wheat prosperous, to prevent post-fermentation of wheat, this type of wheat field should be mastered in the initial period of fertilization, watering.
