Abstract

A planting method for improving maize yield comprises the steps of applying base fertilizer, seeding, planting, primary topdressing, preventing pests and diseases, secondary topdressing, harvesting and the like. The method is characterized in that a sandy loam land which is fertile in soil, convenient to irrigate and drain and good in ventilation is selected to be sufficiently applied with the base fertilizer. Generally, an acre is applied with 20 kilograms of nitrogenous fertilizer, 9 kilograms of phosphate fertilizer, 4.5 kilograms of potash fertilizer and 0.3 grams of potassium sulfate; seeding is carried out when the air temperature is stabilized above 16-17 DEG C, 1.5-2 kilograms of seeds are seeded in each acre, and the planting density is preferably 4000 plants; the primary topdressing is carried out from a seedling stage to a trumpet stage, and the fertilizer type and fertilizing amount are the same as those of the base fertilizer; medicine is applied timely; when maizes just sprout, the secondary topdressing is carried out, and the fertilizer type and fertilizing amount are the same with those of the primary topdressing; and generally, harvesting can be carried out for 20-28 days after the pollination. The method is used for solving the problems of yellow grow corn cob skins, poor maize quality, low market price and poor benefit of waxy corn planting with once fertilizing, and is suitable for planting various maizes.

Description

A kind of implantation methods that improves corn yield

Technical field

The present invention relates to the field of planting of crops, specifically a kind of implantation methods that improves the corn yield quality.

Background technology

At present people are to adopt traditional basal dressing in the plantation of waxy corn, and the method for once topdressing, its shortcoming be, when harvest corn, corncob peel jaundice poor quality, corn yield is low, the market price is low, of poor benefits.

Summary of the invention

The present invention is in the plantation that solves corn, and the fertilizer that once topdresses grows up to rear corncob peel jaundice poor quality, corn yield is low, the market price is low, of poor benefits problem and a kind of implantation methods that improves waxy corn output, quality, benefit of inventing.

The present invention is for addressing the above problem, and the technical scheme that adopts is, a kind of implantation methods that improves corn yield and quality comprises basal dressing, sowing, field planting, once topdresses, diseases prevention worm, secondary such as topdress, gather at the link, and its special character is:

Basal dressing: select fertile soil, irrigation and drainage are convenient, and the good sandy loam soil of ventilating uses sufficient base manure.General 20 kilograms of nitrogen fertilizer applications of mu, 9 kilograms in phosphate fertilizer, 4.5 kilograms in potash fertilizer, 0.3 kilogram of potassium sulphate;

Sowing: 1-10 cm layer of soil ground temperature is stabilized in more than 10 degrees centigrade in the field, temperature is stabilized in more than 16-17 degree centigrade and can sows, and every mu with kind of a 1.5-2 kilogram, sowing depth 2.5-4 centimetre, dressing or spread poison grain powder insect-pest is broadcast rear suitable suppression and is sprouted in order to the seed suction.

Field planting: density field planting 0.4 ten thousand strains are advisable, line-spacing 2 chis, spacing in the rows 0.7-0.8 chi;

Once topdress: 20 kilograms of seedling stage to toy trumpet phase mu nitrogen dressings, 9 kilograms in phosphate fertilizer, 4.5 kilograms in potash fertilizer, 0.3 kilogram of potassium sulphate;

The diseases prevention worm: when corn grows to horn mouth, be filled in the horn mouth with 812 mispickel, cure mainly before and after corn borer August 1 and September 1 front and back beat respectively the first half of corn with chrysanthemum lipid medicine, mainly prevent cotton bollworm;

Secondary topdresses: when corn is just eared, again topdress apart from corn root 5 centimeters, fertile kind, fertilizing amount are with topdressing for the first time;

Gather: 20-28 days main fringes of can gathering after the general pollination.

Embodiment

Basal dressing: select fertile soil, irrigation and drainage are convenient, 1 mu in the good sandy loam soil of ventilating, 20 kilograms of nitrogen fertilizer applications, 9 kilograms in phosphate fertilizer, 4.5 kilograms in potash fertilizer, 0.3 kilogram of potassium sulphate;

Sowing: 1-10 cm layer of soil ground temperature is stabilized in more than 10 degrees centigrade in the field, and temperature is stabilized in 16--17 degree centigrade with upper seeding wheel, with kinds 2 kilograms, and 3 centimetres of sowing depth, dressing or spread poison grain powder insect-pest is broadcast rear suitable suppression and is sprouted in order to the seed suction.

Field planting: density field planting 0.4 ten thousand strains are advisable, line-spacing 2 chis, spacing in the rows 0.8 chi;

Once topdress: 20 kilograms of seedling stage to toy trumpet phase nitrogen dressings, 9 kilograms in phosphate fertilizer, 4.5 kilograms in potash fertilizer, 0.3 kilogram of potassium sulphate;

Diseases prevention worm: when corn grows to horn mouth, be filled in the horn mouth with 812 mispickel, cure mainly corn borer.Beat respectively the first half of corn before and after August 1 front and back and September 1 with chrysanthemum lipid medicine, mainly prevent cotton bollworm;

Secondary topdresses: when corn is just eared, again topdress apart from corn root 5 centimeters, fertile kind, fertilizing amount are with topdressing for the first time;

Gather: 20-28 days main fringes of can gathering after the general pollination.
