Abstract

The invention relates to a planting method for improving the yield and quality of waxy corn. The method comprises the steps of applying a base fertilizer, sowing, field planting, a first time dressing, disease and pest control, a second time dressing, harvesting, etc., and is characterized a sandy land with rich soil, convenient irrigation and drainage and good ventilation and application of the base fertilizer. 20 kilograms of nitrogenous fertilizer, 9 kilometers of phosphate fertilizer, 4.5 kilograms of potash fertilizer and 0.3 kilogram of potassium sulfate are applied for each acre. The sowing is carried out at a temperature more than 16 to 17 DEG C, and 1.5 to 2 kilograms of seeds are sown in each acre. A preferred planting density is 4,000 strains per acre. The first time dressing is carried out during a period from a seedling period to a small bell mouth period with the same kind and amount of base fertilizer. Drug is spread at a proper time. The second time dressing is carried out during the earing period of the waxy corn with the same kind and amount of fertilizer used in the first time dressing. Corn cobs can be picked 20 to 28 days after pollination. The method solves the problems of yellow and poor-quality corn due to once dressing during the planting process, low corn yield, low market price and low benefits and is suitable for planting various waxy corn.

Description

A kind of kind method for planting that improves waxy corn output and quality

Technical field

The present invention relates to the crop planting field, specifically a kind of kind method for planting that improves waxy corn output and 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 waxy corn, and the fertilizer that once topdresses grows up to back corncob peel jaundice poor quality, corn yield is low, the market price is low, of poor benefits problem and a kind of kind method for planting that improves waxy corn output, quality, benefit of inventing.

The present invention is for addressing the above problem, and the technical scheme that is adopted is, a kind of kind method for planting that improves waxy corn output and quality comprises basal dressing, sowing, field planting, once topdresses, diseases prevention worm, secondary such as topdress, gather at 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, broadcast the back suitably suppression sprout 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;

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

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

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

Technique effect

Technique effect of the present invention is, adopts technique scheme, and the strong fringe of stalk is big in the time of can realizing that waxy corn is gathered, and fringe skin pastiness is best in quality, can improve output 20-30%, the kind method for planting of 40% the Good Quality Glutinous Corn of increasing economic efficiency.

Specific 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, 3 centimetres of sowing depth, dressing or spread poison grain powder insect-pest, broadcast the back suitably suppression sprout 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, cure mainly corn borer with 812 mispickel.Beat the first half of corn before and after August 1 front and back and September 1 with chrysanthemum lipid medicine respectively, mainly prevent cotton bollworm;

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

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