Description

The implantation methods of Semen Maydis

Technical field

The present invention relates to proportion of crop planting technical field, the implantation methods of a kind of Semen Maydis.

Background technology

Semen Maydis is the first generalized grain crop of China, but corn yield in the market is the highest, it is impossible to meet user Demand.

Summary of the invention

The invention provides the implantation methods of a kind of Semen Maydis, including:

(1) wholely: after Soil tillage, every mu uses sufficient base manure with well-rotted farmyard manure 1000-1500kg, potassium chloride 7～9kg；

(2) sowing: elite seed before sowing, removes the seed of granule, infected seed, blighted grain, basks seeds 2～3 days；Seed is placed on 32～34 DEG C of water soak 8～10h, is then put under 26～28 DEG C of room temperature conditions infiltration accelerating germination；By row sowing, sowing Time the degree of depth be 12～14cm, 1 seed, spacing in the rows 15～25cm are broadcast in each hole, and Gansu Province is away from 20～25cm；

(3) topdressing: when Semen Maydis grows to 4～5 leaves, mu executes well-rotted farmyard manure 1600～1800kg；Long at Semen Maydis During to 7～9 leaves, mu potassium application 5～7kg；When Semen Maydis grows to 12～15 leaves, mu sealing fertilizer 16～ 18kg ；After topdressing, intertillage to be carried out is loosened the soil every time, ridging lid fertilizer；

(4) field management: weeds, with seeing with removing, should carry out the prevention and control of plant diseases, pest control in time, rationally water according to rain event then；

(5) gather: after Semen Maydis maturation, gather in time.

As a further improvement on the present invention: in described step (3) compound fertilizer the mass percent of nitrogen be 35%, phosphorus Mass percent is 5%, the mass percent of potassium is 5%.

The invention has the beneficial effects as follows: use the implantation methods of the present invention, it is possible to improve the quality of Semen Maydis greatly, thus Meet the demand of user.

Detailed description of the invention

The invention discloses the implantation methods of a kind of Semen Maydis, including:

(1) wholely: after Soil tillage, every mu uses sufficient base manure with well-rotted farmyard manure 1000-1500kg, potassium chloride 7～9kg；

(2) sowing: elite seed before sowing, removes the seed of granule, infected seed, blighted grain, basks seeds 2～3 days；Seed is placed on 32～34 DEG C of water soak 8～10h, is then put under 26～28 DEG C of room temperature conditions infiltration accelerating germination；By row sowing, sowing Time the degree of depth be 12～14cm, 1 seed, spacing in the rows 15～25cm are broadcast in each hole, and Gansu Province is away from 20～25cm；

(3) topdressing: when Semen Maydis grows to 4～5 leaves, mu executes well-rotted farmyard manure 1600～1800kg；Long at Semen Maydis During to 7～9 leaves, mu potassium application 5～7kg；When Semen Maydis grows to 12～15 leaves, mu sealing fertilizer 16～ 18kg ；After topdressing, intertillage to be carried out is loosened the soil every time, ridging lid fertilizer；

(4) field management: weeds, with seeing with removing, should carry out the prevention and control of plant diseases, pest control in time, rationally water according to rain event then；

(5) gather: after Semen Maydis maturation, gather in time.

In described step (3) compound fertilizer the mass percent of nitrogen be 35%, the mass percent of phosphorus be 5%, the quality of potassium Percent is 5%.

The invention has the beneficial effects as follows: use the implantation methods of the present invention, it is possible to improve the quality of Semen Maydis greatly, thus Meet the demand of user.

Above content is to combine concrete preferred implementation further description made for the present invention, it is impossible to assert Being embodied as of the present invention is confined to these explanations.For general technical staff of the technical field of the invention, On the premise of present inventive concept, it is also possible to make some simple deduction or replace, all should be considered as belonging to the present invention's Protection domain.
