preparation example Construction

[0027] The embodiment of the present invention also provides a method for preparing foliar fertilizer, which includes the following steps:

[0028] In parts by weight, mix 5-10 parts of melatonin, 20-36 parts of borax, 15-20 parts of sodium selenate, and 0.5-1.0 parts of graphene oxide to obtain selenium-rich auxin;

[0029] Hoagland nutrient solution and selenium-enriched auxin are mixed uniformly in a mass ratio of 1 to 2:1 to obtain foliar fertilizer.

[0030] Among them, the preparation method of the selenium-enriched auxin is: borax is prepared into a 0.1-1mol / L aqueous solution, graphene oxide is added to the aqueous solution and stirred for 15-25min to obtain a first mixed solution, and sodium selenate is added to the first mixed solution And stir for 20-35 minutes to obtain a second mixed liquid, and mix the second mixed liquid evenly with melatonin after drying; the stirring speed is 150-250 r / min, and the drying temperature is 45-55°C.

[0031] This embodiment provides a sel...

Embodiment 1

[0046] This embodiment provides a method for planting selenium-enriched rape, which includes the following steps:

[0047] S101. Sowing: Select 5 acres of field in the outskirts of Xiaogan City, Hubei Province for experiment; after harvesting the middle rice, plow the field, apply 35kg of compound fertilizer, 60 daltons of soil and manure, 0.2kg of holding force boron on the surface of the box as base fertilizer and base fertilizer per mu Immediately after spreading, rake and rake thin, open the "three ditch", in which the ditch is 1.2 meters wide and the ditch depth is 0.4 meters; then use drill sowing, sowing four rows per box, and the seeding amount is 0.5kg / mu.

[0048] S102. Weeding: After sowing and covering the soil, use 50mL of Henes per mu with 50kg of water to spray evenly on the surface of the compartment.

[0049] S103. Thinning and fixing seedlings: After the true leaves are present, the seedlings are thinned twice, and the seedlings are fixed at the three-leaf stage, so...

Embodiment 2

[0057] This embodiment provides a method for planting selenium-enriched rape, which includes the following steps:

[0058] S201. Sowing: 5 acres of field were selected in the suburbs of Xiaogan City, Hubei Province for experiment; after the middle rice was harvested, the field was plowed, 40kg of compound fertilizer, 65 daltons of soil manure, 0.5kg of borax were applied per acre as the bottom fertilizer, and the bottom fertilizer was applied Immediately raked and rake thin, opened the "three ditch", of which the ditch width is 1.4 meters, the ditch depth is 0.3 meters; afterwards, the hole planting is used for sowing four rows per box, and the seeding amount is 0.4kg / mu.

[0059] S202. Weeding: After sowing and covering the soil, use 100g of acetochlor per acre with 50kg of water to spray evenly on the surface of the compartment.

[0060] S203. Thinning and fixing seedlings: After real leaves are present, the seedlings are thinned twice, and the seedlings are fixed at the three-leaf...

Abstract

The invention discloses a selenium-rich auxin, a foliar fertilizer, a method for preparing the same and a method for planting selenium-rich oilseed rape, and belongs to the technical field of fertilizers. The selenium-rich auxin comprises, by weight, 5-10 parts of melatonin, 20-36 parts of borax, 15-20 parts of sodium selenate and 0.5-1.0 part of graphene oxide. The foliar fertilizer contains the selenium-rich auxin. The selenium-rich auxin, the foliar fertilizer and the methods have the advantages that the shortcoming of antagonistic conflict of oilseed rape during boron and selenium absorption can be overcome by the aid of the selenium-rich auxin, and the fertilizer absorption and utilization rates of the oilseed rape can be increased.

Description

Technical field [0001] The invention belongs to the technical field of fertilizers, and particularly relates to a selenium-enriched auxin, a foliar fertilizer and a preparation method thereof, and a selenium-enriched rapeseed planting method. Background technique [0002] Brassica napus L. (Brassica napus L.), also known as European rape, is commonly known as oilseed rape, which belongs to the Brassica family and Brassica family. Rapeseed is one of the most important oil crops in my country. The annual planting area is up to 110 million mu and the annual output is more than 12 million tons. The rapeseed oil prepared from rapeseed accounts for 60% of the domestic vegetable edible oil. Planting occupies a very important position, which plays an important role in ensuring the safety of my country's oil supply and promoting farmers' income. In addition to oil extraction, rape has a wide range of uses. It can be used as animal green feed, green manure, flower landscapes and vegetables...
