Abstract

The invention discloses a fruit corn planting technology, belongs to the technical field of agricultural planting, and in particular relates to a fruit corn planting method. The fruit corn planting technology has the advantages that fruit corns are full in particle, small in size difference and strong in disease resistance. The fruit corn planting technology comprises the following steps: 1, choosing seeds, i.e., choosing an excellent variety suitable for local planting; 2, performing insulated planting, i.e., strictly insulating from common corn varieties in soil choosing and planting to avoid quality reduction caused by mutual pollination; 3, finely preparing soil, and finely growing seedlings, , i.e., preparing the soil finely in planting and choosing plots which are loose in soil texture, fertile in soil and convenient in irrigation and drainage; 4, performing field management, comprising main technical measures of checking fields and filling the gaps with seedlings; when the fruit corns grow to a 3 to 4 leaf stage, thinning and transplanting seedlings to fill a vacancy, wherein the soil must be brought in seedling transplantation; 5, scientifically applying fertilizer, i.e., applying sufficient base fertilizer as the harvest time of the sweet corns is earlier than that of common corns.

Description

Fruit corn planting technology

Technical field

The invention belongs to agricultural plantation technology field, especially relate to a kind of implantation methods method of fruit corn.

Background technology

Fruit corn, also known as sweet corn or vegetable corn, grass family, Zea, the saccharoid type subspecies of Semen Maydis.Fruit corn is a kind of super-sweet corn being suitable for eating something rare, and stage skin is thin, juice is many, matter is crisp and sweet for blue or green rod, can directly eat something rare; very thin epidermis is once stinging brokenly, and the juice of delicate fragrance overflows tooth cheek, eat something rare ripe eat the sweetest, the most crisp; as fruit, be therefore referred to as " fruit corn ".Fruit corn seed is yellowish or milky, and embryo is relatively big, and milk stage is real tender, the most delicious, rich in water soluble polysaccharide, vitamin A, vitamin C, fat and protein etc..At present, fruit corn has a large amount in variety, and all has the highest nutritive value.But fruit corn easily occurs pathological changes, the problem that fruit size differs, granule is the fullest in planting process.

Summary of the invention

The present invention is aiming at the problems referred to above, it is provided that a kind of full grains, a kind of fruit corn planting technology that size difference is less and resistance against diseases is strong.

To achieve these goals, the present invention adopts the following technical scheme that.

Fruit corn planting technology, it is characterised in that comprise the following steps.

One. initial point selection, first initial point selection is intended to select the kind of excellent applicable local plantation.Fruit corn kind should select kind of a source to fix, purchase kind for kind of a reliable unit, should first carry out little area and plant experimentally when introducing a fine variety, establishing in large scale again after acquirement experience.Additionally choosing seeds also should be according to producing purpose, selection type.As listed based on young tender fruit ear as fruit and vegetable, super-sweet corn kind should be selected；To do tin product, then should select common Sweet corn variety.

Two. isolation implant, when selection of land is planted, strictly to isolate with other conventional corn kind, to avoid reducing quality because mutually going here and there powder.Partition method produces upper employing spatial separation and time isolation.Preferably spatial separation.Spatial separation, it is desirable to do not plant other corn variety in the range of growing area peripheral 300～400m, if any the natural cover for defense such as forest, hummock, can suitably shorten isolation spacing.Time isolates, if spatial separation can not be carried out, then the method for time isolation (staggering sowing time) should be taked to avoid the flower synchronization with other kind, and the interval time in sowing time of 2 different cultivars is generally 20～25 days.Plant sweet corn such as large area in flakes, can suitably reduce isolation standard.

Three. the most wholely, due to the general seed of fruit corn seed compared with flat, grain is little, germinate, encircle soil, ratio conventional corn seed difficulty of emerging, so wanting fine nursery, will be the most whole when plantation, select that the soil is porous, fertile soil, the convenient plot of irrigation and drainage.Ploughing 30～35cm in time after preceding crop results, use sufficient base manure in conjunction with ploughing, general every 667m2 organic fertilizer 1200～1500kg, zinc sulfate 1～1.50kg or corn fertilizer 20kg makees base manure.

Four. field management, the technical measures of field management has: one is to look into field to fill the gaps with seedlings.When fruit corn grows to 3-4 leaf phase, thinning and transplanting seedlings is filled a vacancy, when transplanting seedlings will band soil, i.e. water after cultivation, the most between the lights or the cloudy day is carried out.Two is the final singling of leaf phase, and 1 strain is stayed in every cave, and combines the middle weeding that topdresses.Earthed up before jointing stage to typhon mouth phase.Three is reasonable irrigation and drainage, and seedling stage, soil moisture was when the 60%-70% of water-holding capacity, can not pour water.

Five, apply fertilizers scientifically, owing to sweet corn wants Zao than conventional corn collection period, it is therefore necessary to accomplish to use sufficient base fertilizer, rationally fertilizer ratio, on the basis of executing decomposed manure 2000 kilograms at every mu, it is proposed that mu applies NPK 15～20 kilograms of base fertilizer, to ensure the sweet corn demand to nutrient.The fertilising of Semen Maydis, should determine according to indexs such as fertilizer requirement, soil nutrient quantity delivered, utilization rate of fertilizer and scheduled productions.The most once topdress with the pustulation period at jointing stage, heading flowering period.

As a kind of preferred version, prevention and control of plant diseases, pest control fruit corn plant is sweeter than conventional corn, easily causes the insects such as Pyrausta nubilalis (Hubern)., chafer, aphid, therefore, it is necessary to do a good job of it insect in seedling stage and the preventing and treating of middle and late stage Pyrausta nubilalis (Hubern)..In order to prevent alimentary toxicosis, at middle and late stage pesticide to be cautious use of, Biological control insect pest to be used after pollination, less with chemical pesticide, must not be with the hypertoxic high-toxic pesticide of longevity of residure length.Preventing and treating subterranean pest-insect, every mu of use 3% meter Le Er granule 5 kilograms, mixed fine sand spreads fertilizer over the fields at seed furrow；Preventing and treating Pyrausta nubilalis (Hubern). can inoculate trichogramma pieces of an egg in the typhon mouth phase, fills lobus cardiacus with bacillus thuringensis, Beauveria Bassiana Powder etc..Chemical control before taking out hero, floral leaf rate for preventing and treating the suitable phase when reaching 10%, available 80% DDT EC 2500～3500 times of liquid, every strain 12-17ml fills the heart, and prevention effect reaches more than 85%, and double can control Semen Maydis thrips.

Beneficial effect of the present invention.

The present invention processes the artificial supplementary pollination of loose powder phase in good time, can make full seed, if the artificial supplementary pollination to be strengthened when the loose powder phase runs into the most overcast and rainy.For reducing nutrient consumption, after pollination terminates, tassel all can be cut off.Corn particle so can be made full, and size difference is little, and resistance against diseases is greatly increased.
