Jointing stage is the critical period for the differentiation of florets, stamens and stamens, formation of drug septum, internode elongation and bipolarization. Spike differentiation requires more nutrients, adequate nutrients, short and thick internodes, long internode extensions, multiple spikelets and florets, and corresponding increase in kernels. Therefore, timely application of joint fertilizer is very important.
The topdressing method of wheat jointing fertilizer: after the basic fixed length (5-7 cm) in the first base of wheat, the urea urea 7.5-10 kilograms will be applied, which will neither promote the elongation of the end of the third quarter nor increase the invalidity. Spike can also reduce the deterioration of spikelets and florets, achieve large grains, increase grain weight, and increase yield.
Second, the booting phase can not be top dressing, how to top dressing?
The booting period is the most vigorous growth period in wheat. The area of ​​the leaf increased rapidly, the stalk swiftly elongated, the young panicle differentiated and grew, and the accumulation of dry matter was fastest. Therefore, the response to fertilizer and water at this period is very sensitive. Soil drought or nutrient deficiency will seriously affect the leaf area expansion and ear and flower development; however, if the fertilizer is too much water, the stems and leaves will be covered and the light between the plants will be poor and even occur. Lodging.
Fertility nutrition at the booting stage not only has a direct impact on the number of spikes and grains, but also has an indirect effect on grain filling and grain weight at the later stage. The differentiation of young panicles to the palliative period, especially the meiosis period, is the critical period for fertilizer, water, and nutrition. If the leaf color of the flag leaflets fades, there is a premature aging phenomenon, and urea should be supplemented with 4-5 kg ​​per mu. In order to give full play to the advantages of wheat more solid.
Cable seal is a kind of security seal with a metal locking body and a piece of cable.
