Embodiment 1

[0012] Embodiment 1: Within 10 days (October 20-October 30) before the ground was frozen in the previous year or after the plow layer melted in the early spring of the year (late April), use a seven-share plow to form a ridge in combination with a soil preparation machine. Apply nitrogen, phosphorus and potassium formula fertilizer deeply. Before fertilization for site preparation, prepare formula fertilizer according to the ratio of urea: diammonium: potassium sulfate = 2.8:1:2.3, mix urea, diammonium, and potassium sulfate, mix them well, and put them in bags for later use (the amount of fertilizer configured should not exceed before the soil preparation machine goes into the ground, put a small amount of compound fertilizer into the fertilizer box, and test the amount of fertilizer applied on the side of the road or on the ground to make the amount of fertilizer applied meet the requirements of the planting plan; Adjust the depth to 15-20cm below the top of the ridge after ...

Embodiment 2

[0013] Embodiment 2: When plowing in the spring of that year, combine the seeding once with the precision demand seeder and deeply apply nitrogen, phosphorus and potassium formula fertilizer. Before sowing, prepare nitrogen, phosphorus and potassium formula fertilizer according to the ratio of urea: diammonium: potassium sulfate = 2.8: 1: 2.3, mix the three fertilizers of urea, diammonium and potassium sulfate, mix well, and pack them in bags for later use (the configured fertilizer before the planter goes to the ground, put a small amount of formula fertilizer into the fertilizer box, and test the amount of fertilizer applied on the side of the road or on the ground, so that the amount of fertilizer applied meets the requirements of the planting plan; after the planter enters the ground, put the fertilizer Fill the tank with formula fertilizer, adjust the fertilization ditch opener to make it 10-15cm lower than the sowing ditch opener; in the process of sowing and fertilizing,...

Abstract

The invention discloses a waxy corn formulated fertilizer and a single-dose mechanized deep fertilization method thereof. The waxy corn formulated fertilizer solves the problems that the manual top dressing in seedling stage wastes time and the chemical fertilizer utilization ratio is low. Concretely, nitrogen, phosphorus and potassium in the waxy corn formulated fertilizer have the weight part ratio that N: P2O5: K2O equals 1.9 to 3.2: 1: 0.5 to 2.5, and the fertilizer has the proportioning by weight that carbamide: diammonium: lemery equals 1.5 to 2.8: 1: 0.5 to 2.3. The invention provides the fertilization method that the formulated fertilizer is put in a fertilizer box of a seeding fertilizer applicator, a fertilizer hole on the lower part of the fertilizer box is adjusted, the applied amount of fertilizer is measured according to the requirement of the planting scheme, the soil tillage and the ridge forming are combined in autumn and spring or the formulated fertilizer is fertilized to ridge bodies when in spring sowing, and the fertilizer application depth is 15 to 20cm under ridges or 10 to 15cm under seeds. The waxy corn formulated fertilizer and the single-dose mechanized deep fertilization method thereof satisfy the nutrient requirements at each stage during the growth and development process of the waxy corn, save man-day/hm<2> for the top dressing, raise the nitrogen utilization efficiency by 10 percent, raise the fresh ear yield by 8 percent, and reach 15280 kg/hm<2>.

Description

technical field [0001] The invention relates to a formula fertilizer for waxy corn and its one-time mechanical deep application method. Background technique [0002] Waxy corn is a sunrise industry whose production target is green food. With the improvement of people's living standards and food culture, the market for glutinous corn fresh food products is in short supply. The rapid development of the quick-frozen fresh product processing industry has led to the rapid expansion of the waxy corn planting area. However, according to the conventional planting method, the growers use phosphorus and potassium fertilizers as base fertilizers in combination with sowing, and nitrogen fertilizer (urea) is artificially topdressed at the seedling stage, that is, combined with intertillage in the early stage of seedlings, and urea is sprinkled on the seedling eyes after shoveling and before shoveling. , Cover with soil, wait for the rain to melt and sink into the soil; use a hoe to dig...
