Abstract
The invention relates to a method for planting sweet corn, and belongs to the technical field of crop planting. The method is characterized in that spatial isolation planting is adopted, that is, the sweet corn is 300 meters to 400 meters spatially isolated from normal corn and waxy corn, so as to prevent quality reduction caused by cross pollination, and maintain the flavor of the sweet corn; the content of starch in seeds of the sweet corn is small, and the sprouting capacity and the soil pushing capacity are relatively poor, therefore, land blocks being loose in soil, good in fertility and soil moisture content, and convenient for irrigation and drainage are selected during planting. Experiments show that the quality of the sweet corn planted with the method is not reduced.
Description
Technical field
The present invention relates to the implantation methods of a kind of sweet corn, belong to proportion of crop planting technical field.
Background technology
Sweet corn, also known as vegetable corn.Because of its have abundant nutrition, sweet, fresh, crisp, tender characteristic and deeply by each stratum consumers.Cooking is eaten raw, sweet with its food flavor, and digestibility is high, is loved by the people.Sweet corn is extensively planted due to sugar content height, suitable collection period length.Because planting the better economic benefit of sweet corn, popularizing area is increasing.But the easy mutation of method of plantation at present.
Summary of the invention
For overcoming current implantation methods Problems existing, the present invention provides the implantation methods of a kind of sweet corn.
The present invention realizes with following technical scheme: the implantation methods of a kind of sweet corn, specific as follows "
One, selection of land
Employing spatial separation is planted, and namely the quality that the spatial separation of 300-400 rice causes to prevent string powder should be had to decline with conventional corn, Glutinous Semen Maydis, keep the local flavor of sweet corn；Owing in sweet corn seed, content of starch is few, germinate and arch soil ability is more weak, therefore, to select that the soil is porous, fertility good when plantation, convenient plot is arranged in good conditions for soil moisture, filling；
Two, finely wholely, using sufficient base manure, upper seeding is carefully broadcast
Use sufficient base manure during whole ground, execute high-quality decomposed dung 1000～1500kg for every mu, separately add calcium superphosphate 15kg be sufficiently mixed macerate ripe after, apply prior to seeding；Sowing wants fine, and 3～4, every cave, depth of planting is slightly more shallow than conventional corn, general earthing about 4cm.
Three, rational close planting
Planting density is determined according to breediness, soil fertility, morning and evening date of seeding, planting patterns, notes the commodity performance of fruit ear simultaneously；At general medium fertility soil, being advisable with 4000 plants/acre, early-maturing variety can be closeer, and late variety can be rarer.
Four, field management
1) look into Seedling to fill the gaps with seedlings, thinning final singling
After emerging, Seedling should be looked in time and fill the gaps with seedlings；The thinning when seedling has 3～4 leaves, final singling during 4～5 leaves；The principle of thinning be except big, except little, stay centre, to ensure full field seedling uniformity；
2) pay attention to topdressing, intertill in time
General mu imposes fertilizer or farmyard manure about 1000kg, carbamide 30kg, potassium chloride 5～7kg；Potash fertilizer and fertilizer or farmyard manure disposable imposed in seedling stage；Topdress deep placement of as far as possible spreading manuer in holes, timely earthing after executing.
3) meet drought to water
Pour water in time in seedling stage, typhon mouth phase and pustulation period；
4) prevention and control of plant diseases, pest control
To subterranean pest-insect, add fine sand 25～30kg seedling stage every mu with phoxim 0.5kg and spread fertilizer over the fields；Pyrausta nubilalis (Hubern). Furadan granule was spread fertilizer over the fields latter stage in lobus cardiacus phase or lobus cardiacus；
Five, fringe period management
Bud fertilizer, every mu of sealing fertilizer 50-60 jin+15 jin of potash fertilizer are attacked in the phase heavy dressing of weaving silk.Broadcast application in face, ridge, in conjunction with pouring water or rainwater allows fertile absorption.Fruit ear is promoted to grow and solid full top.Within 10 days, it is the moisture-sensitive phase before and after heading pollination, can not be arid, keep the water-holding capacity 70%-80% in soil field；After sweet corn fruit ear is formed, can not cut off the water supply too early, cause plant senilism, it should keep the field water yield.
1 strain Semen Maydis only stays 1 fringe in principle.Only stay main spike length to become when weaving silk, the small ear below main fringe is divested in time, in order to the main fringe of nutrition centralizedly supply.Extract as the second luxuriant and following little bud filigree discharge 2-3cm, can sell as sweet corn Radix Crotalariae szemoensis；Extracing after small ear, visual Seedling gesture executes a granulated fertilizer, can spray potassium dihydrogen phosphate, foliage fertilizer, or executes+5 jin of potash fertilizer of 15 jin of carbamide and combine and pour water or rainwater；
Six, timely collecting
Its marketing quality and nutritional quality are affected greatly by the harvest time of sweet corn.Crossing early harvest, seed inclusions is less；Results are late, then peel is hardening, slag is many, loses the distinctive local flavor of sweet corn；In general, suitable harvest time is within 20～23 days, to be advisable after pollinating with fruit ear；Namely sweet corn must be gathered in the crops in milk stage；Results standard: sweet corn fruit ear bract is dark green, parcel is relatively tight, and filigree is withered goes to dark brown, and seed enlarged volume is to maximum, bright in colour, and extruding seed has serum to flow out.
Collecting time should carry out before at 9 in the morning or after at 4 in afternoon, stacks easily heating and goes bad, be suitable for spreading at shady and cool ventilation place, apply refrigerator car or means of transportation on the rocks summer, to keep fresh fringe quality after fruit ear harvesting.
