Abstract

The invention discloses the nursery resistant to lodging of a kind of sweet corn and cultivation method, comprise the following steps: the whole soil pit dish that 1) applies fertilizer is for subsequent use; 2) seed sowing cave dish; 3) seedling is completely cured after all sprouting; 4) ventilate before transplanting and practice seedling; 5) green manure sweet potato is sowed; 6) sweet potato is turned over into field; 7) transplant, after cultivation, water normal root water ridging covering with plastic film.The advantages such as the present invention has nursery and breeding program is easy, saving of work and time, sweet corn root growth is healthy and strong, aerial root occurs early, improve plant soil effective fertility, soil transparency increases, soil weeds in field significantly reduces, and sweet corn product quality significantly improves, and output comparatively traditional cultivation improves 15 ~ 20%.The method that the present invention adopts seedling to be completely cured, reduces root soil humidity, promote side root and aerial root and premature eruption, improves root system total amount 10 ~ 25%, enhances the lodging tolerance of sweet corn.

Description

Sweet corn nursery resistant to lodging and cultivation method
Technical field
The present invention relates to a kind of continuous cropping no-tillage cultivation method of melon and fruit, especially a kind of muskmelon continuous cropping no-tillage cultivation method, belongs to field of plant growing technology.
Background technology
Sweet corn, also known as vegetable corn, is the saccharoid type subspecies of corn.Sweet corn has abundant nutrition, sweet, fresh, crisp, tender and glutinous characteristic and dark in each stratum consumers because of it, and edibility is high, is widely used as the nutriment kept healthy.
Sweet corn lodging is that lodging is the key factor affecting corn yield and quality, and according to statistics, lodging causes the corn underproduction 15% ~ 25% because the stem stalk of extraneous factor initiation is from erectility to the phenomenon of falling to roll over.China is every year because lodging causes nearly 1,000,000 tons of the production loss of corn.Improving constantly along with maize culture level at present, the contradiction of dense planting and lodging, and due to a lot of uncertain natural cause generation, cause corn lodging to cause production loss to present the trend of aggravation.
Summary of the invention
The object of the invention is the defect overcoming the culture technique existence resistant to lodging of existing sweet corn, the nursery resistant to lodging of a kind of sweet corn and cultivation method are proposed, adopt in this way, sweet corn plant strain growth is good, root system development is healthy and strong, enhance sweet corn lodging tolerance, improve the Yield and qualities of sweet corn.
The present invention is achieved by the following technical programs:
A kind of sweet corn nursery resistant to lodging and cultivation method, comprise the following steps:
1) select the good sandy loam of loosing soil fertility to add decomposed manure 5: 2 mixings in proportion, with Baijunling sterilization, places and to load 128 caves or 72 caves, cave after 10 days and coil for subsequent use;
2) ground paving thin film, puts the cave dish after dress soil according to the order of sequence on film, basks seeds 1 day before broadcasting, by Pan Jiao vola, ready cave water, live by 1/cave dry seeds, the thick fine earth of lid 1 ~ 1.5cm, then covers thin film or sunshade net;
3) after seedling all sprouts, control temperature is at 17 ~ 24 DEG C, and humidity is 62% ~ 68%; When seedling grows to 2 leaf 1 heart, mentioned by cave dish, corn seedling main root has grown cave tray bottom leaking hole about 2 ~ 10cm, all cuts off all main roots along cave tray bottom; Seedling grows to 3 leaf 1 hearts, when the new root of hair system in bottom stretches out cave tray bottom leaking hole about 0.5 ~ 2cm again, and transplanting of going to the field;
4) transplant and start the experienced seedling that progressively ventilates the last week, transplant first 3 days, cave dish is placed in canopy and practices seedling outward by whole day, strengthens the resistance of seedling;
5) the glutinous loam of crop rotation is selected, the plot of middle fertility, nothing plantation conventional corn within 200m around land used; 7 ~ August before cultivation, sow one season green manure sweet potato;
6) 2 ~ March of Second Year, green manure sweet potato is turned over into field, applies base fertilizer composite fertilizer 20kg/667m 2, fertilizer 1000kg/667m 2, cultivate first 20 days ridging covering with plastic film;
7) fine day in the afternoon 4 time after transplant, water normal root water after cultivation; Adopt the plantation of duplicate rows district, after field planting, control measures are identical with conventional corn.Within 21 ~ 24 days after female fringe is weaved silk, can gather.
Object of the present invention can also be realized further by following technical measures.
The nursery resistant to lodging of aforesaid sweet corn and cultivation method, the high 22 ~ 28cm in ridge, row spacing 75 ~ 85cm in wherein said step 5), wide 2535cm between ridge.
The nursery resistant to lodging of aforesaid sweet corn and cultivation method, spacing in the rows 33 ~ 38cm in wherein said step 7), line-spacing 50 ~ 60cm, planting density is every mu of 3000 ~ 3500 strains.
Compared with existing sweet corn cultivation method resistant to lodging, the advantages such as the present invention has nursery and breeding program is easy, saving of work and time.Sweet corn root growth is healthy and strong, and aerial root occurs early, to improve plant soil effective fertility, soil transparency increases, and soil weeds in field significantly reduces, and weeds fresh weight amount reduces by 80%, sweet corn product quality significantly improves, and output comparatively traditional cultivation improves 15 ~ 20%.The method that the present invention adopts seedling to be completely cured, reduce root soil humidity, promote side root and aerial root and premature eruption, improve root system total amount 10 ~ 25%, root system development is healthy and strong, plant base portion rugosity cultivating plants base portion rugosity of not more being completely cured increases thick about 0.5 ~ 2.0cm, enhances the lodging tolerance of sweet corn.Present invention employs sowing sweet potato green manure, turn over into field, in conjunction with the method for plastic mulching, make soil available nitrogen recruitment reach 80. 8 ~ 88. 5% of green manure burst size, improve recycling of potassium, promote the robust growth of sweet corn root system and plant.Sweet potato salt tolerance effects is fairly obvious, and its effect reaches about 80%, promotes that the equilibrium of soil nutrient utilizes, for new way has been opened up in sweet corn cultivation resistant to lodging.
Advantage and disadvantage of the present invention, the non-limitative illustration by preferred embodiment below made an explanation, these embodiments only provide as an example.
Embodiment
Below in conjunction with the embodiment of " Hua Zhen " sweet corn, the invention will be further described.
The present embodiment comprises the following steps:
1) select the good sandy loam of loosing soil fertility to add decomposed manure 5: 2 mixings in proportion, with Baijunling sterilization, places and to load 128 caves, cave after 10 days and coil for subsequent use.
2) ground paving thin film, puts the cave dish after dress soil according to the order of sequence on film, basks seeds 1 day before broadcasting, by Pan Jiao vola, ready cave water, live by 1/cave dry seeds, the thick fine earth of lid 1 ~ 1.5cm, then covers thin film or sunshade net.
3) after seedling all sprouts, control temperature is at 17 ~ 24 DEG C, and humidity is 62 ~ 68%; When seedling grows to 2 leaf 1 heart, mentioned by cave dish, corn seedling main root has grown cave tray bottom leaking hole about 2 ~ 10cm, all cuts off all main roots along cave tray bottom; Seedling grows to 3 leaf 1 hearts, when the new root of hair system in bottom stretches out cave tray bottom leaking hole about 0.5 ~ 2cm again, and transplanting of going to the field.
