Abstract

The invention discloses a corn planting method comprising the steps of seed selection, field preparation, planting, daily management, and harvesting. According to the invention, a variety of innovative approaches are adopted, and modern research results are utilized. A JT composite strain-type II is used, such that diseases can be effectively prevented during a planting process, and corn nutrient element absorption can be enhanced. In the aspect of fertilization, corn's requirements on nitrogen, phosphorus and potassium during the growth process are emphasized, and the requirements on trace elements such as boron, zinc, manganese, iron, copper, praseodymium, europium, ytterbium, lutetium and holmium are also taken into consideration. During fertilization, reasonable increase or decrease is made according to corn fertilizer uptake differences in different growth periods. Therefore, corn yield can be increased, and the environment can be protected. Also, during daily management, weed removal is emphasized, and a good growth environment for corn is ensured. In the aspect of harvesting, real-time late harvesting is adopted, such that yield can be improved.

Description

A kind of implantation methods of corn

Technical field

The present invention relates to field of agricultural cultivation, particularly relate to a kind of implantation methods of corn.

Background technology

Corn plants one of crops the most widely in world agriculture, as Three major grain crops, because of the product that it is abundant

Go out and higher use value and be described as " gold " industry.China has a large population, planting soil ground area is little per capita, this just requires that unit are corn yield increases, present maize high-yield culture technique, many employings enrich azophoska, research show blindly enrich the object that N P and K does not only have volume increase, can the underproduction be caused on the contrary, heavy dressing simultaneously, also very serious to environmental disruption.

Summary of the invention

The object of this invention is to provide a kind of implantation methods of effective raising corn yield.

The technical scheme taked in order to the present invention that solves the problem is:

An implantation methods for corn, comprises the following steps:

(1) choose seeds: select the corn variety that good quality and high output, yielding ability are strong, grand flat 206;

(2) whole field: subsoiling, deeply revolve, carefully harrow, suppress, subsoiling 30 centimetres to 45 centimetres, deeply revolve 25 centimetres, thin rake, suppression reach defincienct in the upper and excessive in the lower without clod, the Horizon ridge is straight without hollow hole, full dose is applied fertilizer, the composite fertilizer 80 kilograms of mu basal dressing nitrogen, phosphorus, potassium each 15%, farmyard manure 3 cubic nonlinearity boron, zinc, manganese, iron, the micro-fertilizer of copper and RE microbial fertilizer;

(3) plant: annual sowing in-15 days on the 10th June, during sowing, spacing 15-18cm between strain and strain, after seed germination, every mu is stayed able-bodied seedling 6500-6800 strain;

(4) daily management: after seed germination, executes JT composite bacteria-II type, chemical weed control during 7 leaves, adopts 40% atrazine colloidal suspending agent+72% all that missible oil, sprays the control of carrying out of chlormequat during 12 leaves; Shooting stage, execute urea 25kg, diammonium phosphate 50kg for every mu, potassium chloride 50kg; In the grouting later stage, every mu sprays potassium dihydrogen phosphate 50g and RE microbial fertilizer 1.3kg, accomplishes that drought fills with flood row;

(5) gather in the crops: the harvest season, if meet fine heat weather short of rain, can receive for 1 week evening in real time.

As the further scheme of the present invention: 1.4kg executed by the micro-fertilizer every mu of described boron, zinc, manganese, iron, copper.

As the further scheme of the present invention: described RE microbial fertilizer is praseodymium, europium, ytterbium, lutetium, holmium RE microbial fertilizer, and the every mu of amount of executing is 300g.

As the further scheme of the present invention: chemical weed control during described 7 leaves, every mu of 40% atrazine colloidal suspending agent executing 120ml and 180ml 72% all you missible oil tax water 50L spray.

Beneficial effect of the present invention: the present invention adopts multiple innovation gimmick, utilizes modern study result, uses JT composite bacteria-II type, effectively can prevent the generation of disease in planting process, can also increase the absorption of corn to nutritive element; In fertilising, not only focus on the demand to N P and K in corn growth, take into account the demand to trace elements such as boron, zinc, manganese, iron, copper, praseodymium, europium, ytterbium, lutetium, holmiums simultaneously, when applying fertilizer, according to each growth period of corn, the difference that fertilizer absorbs rationally is increased and decreased, namely reach increase corn yield, realize again the object of protection of the environment; Simultaneously when daily management, focus on the removal to weeds, ensure the growing environment that corn is good; In results, adopt receive evening in real time, to reach the object improving output.

Embodiment
