Problems solved by technology

[0012] The present invention aims at problems such as excessive and wasteful input of chemical fertilizers and increased labor costs caused by frequent fertilization during the vegetative growth period of wheat, and the one-time fertilization technology using slow-controlled release fertilizers has unstable effects and high fertilizer prices due to mismatch with the law of fertilizer demand of wheat, and provides a Wheat basal fertilizer and application method without topdressing tillering and turning green fertilizer, to stabilize fertilizer effect, improve fertilizer efficiency and planting benefit while reducing fertilization frequency and chemical fertilizer input, saving labor cost

Embodiment 1

[0030] Embodiment 1 avoids topdressing tillering, the preparation of the wheat basal manure of turning green manure

[0031] Prepare a kind of nitrogenous fertilizer, phosphorus fertilizer, potash fertilizer mass fraction and be 28-12-8, 2 parts of zinc fertilizers, 2 parts of nitrogen fertilizer synergist free from topdressing tillering, the wheat base fertilizer of turning green fertilizer, its specific steps comprise: first obtain from the market Purchase the following fertilizer raw materials, each raw material component is weighed by the following mass parts: 514kg of medium granular urea, 241kg of granular diammonium phosphate, 31kg of granular superphosphate, 133kg of granular potassium chloride, 61kg of granular zinc sulfate containing 33.0% zinc, Dicyandiamide 20kg. The so-called fertilizer raw materials are put together in a mixer and stirred at a speed of 10 rpm for 8 minutes, fully mixed and then sent to a metered package, which is N-P 2 o 5 -K 2O mass parts are...

Embodiment 2

[0032] The stable yield effect of the wheat basal fertilizer of embodiment 2 exempt from topdressing tillering and turning green manure

[0033] From 2016 to 2018, the present invention was tested and demonstrated on three different types of soil in Taizhou City. The three soils were hard soil, small silt soil and high sandy soil, and the soil fertility was in high, medium and low grades respectively. For the target yield, the recommended nitrogen application rates for wheat planting on the three soils are 180kgN / ha, 210kgN / ha and 240kgN / ha, respectively, and the proportions of basal nitrogen (pure nitrogen mass) are 70%, 65% and 60% respectively. For specific implementation, select the contiguous farmlands operated by cooperatives or farms to select wheat fields with basically the same soil fertility, irrigation and drainage conditions, and yields over the years to carry out experiments and demonstrations. The three demonstration sites all took farmers' customary fertilizatio...

Embodiment 3

[0037] Example 3 The wheat basal fertilizer that avoids topdressing until tillers and turns green manure significantly improves the efficiency of nitrogen fertilizer

[0038] Implementation steps are the same as in Example 2. Visible in table 2, use broad-spectrum compound fertilizer (15-15-15) comparison with farmer's customary fertilization, under the condition that chemical fertilizer consumption reduces 24.3%~31.2%, use wheat base fertilizer of the present invention on three kinds of soils and avoid topdressing tillering, Green manure, wheat nitrogen recovery rate, agronomic efficiency and nitrogen partial productivity increased significantly by 16.4%-45.9%, 15.5%-48.1% and 36.1%-39.5%, respectively.

Abstract

The invention discloses a wheat base fertilizer without topdressing of tillers and striking root fertilizers and an application method thereof. The wheat base fertilizer is prepared from the followingcomponents in parts by mass: 24-30 parts of nitrogen fertilizer, 8-12 parts of phosphorus fertilizer, 6-10 parts of potassium fertilizer, 2-4 parts of zinc fertilizer and 1-2 parts of a nitrogen fertilizer synergist, wherein the total mass fraction of nitrogen, phosphorus, potassium is not less than 48 parts. By applying the base fertilizer, wheat can be exempted from the tillers and the strikingroot fertilizers, and one-time topdressing is only carried out in a jointing stage. The wheat base fertilizer is designed to meet the requirements of wheat nutrient requirements. Under the premise ofno topdressing of the tillers and the striking root fertilizers, the base fertilizer can meet the nutrient requirements of the critical period (tiller period) of wheat nutrients and promote pre-winter tiller, a jointing fertilizer can meet the nutrient requirements of the maximum efficiency stage (jointing and booting stage) of the wheat nutrients, and fertilizer removal and premature senescenceare avoided; and thus a stable fertilizer effect is achieved. The problem of excessive fertilizer application caused by too frequent fertilization during the wheat nutrient growth period of wheat is effectively solved, a slight increase in yield can be maintained under the condition that the amount of the fertilizers is reduced by 24.3-31.2%, and the nitrogen fertilizer recovery rate, agronomic efficiency, partial factor productivity and planting benefits are significantly improved.

Description

technical field [0001] The invention relates to the technical field of fertilizers and fertilization, in particular to a wheat base fertilizer free from topdressing tillering and regreening and its application method. Background technique [0002] Wheat is an important food crop in my country. The whole growth period includes three periods, in which the vegetative growth period is from sowing to jointing, the vegetative growth and reproductive growth are parallel periods from jointing to heading, and the reproductive growth period is from heading to maturity. The vegetative growth period of wheat lasts for about three months (generally from late November to the middle and late February of the following year), but the overwintering period (about 2 months) when the growth is basically stagnant is removed, and the vegetative growth period meets the growth conditions of wheat It takes only about 1 month for the fertilizer to work. During this period, in addition to applying bas...
