Abstract
The invention discloses a sweet corn lodging-resistance seedling raising and culturing method including steps of (1) applying fertilizer and preparing soil trays, (2) sowing seeds in the trays directly, (3) performing root excision after seedlings grow neatly, (4) performing ventilative acclimatization to the seedlings before transplanting, (5) planting green manure of vetch, (6) plowing the vetch into fields, and (7) transplanting, watering roots, ridging and then covering mulches. The method has the advantages of simplifying seedling raising and culturing processes, saving time and labor and the like, further, enabling roots of sweet corn to grow strongly, increasing growth speed of aerial roots, improving effective fertility of plant soil and soil permeability, reducing field weed effectively, improving quality of sweet corn effectively and increasing output by 15-20% as compared with that of the conventional culture method. By means of seedling root excision, soil humidity at roots is reduced, growth of lateral roots and aerial roots is accelerated, the root system total is increased by 10-25%, and thus, lodging resistance capacity of sweet corn is improved.
Description
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, belong to field of plant growing technology.
Background technology
Sweet corn, claim again vegetable corn, is the saccharoid type subspecies of corn.Sweet corn is because it has abundant nutrition, sweet, bright, crisp, tender and glutinous characteristic is favored by the consumer of each stratum deeply, and edibility is high, the nutriment that is widely used as keeping healthy.
Sweet corn lodging is the stem stalk that causes due to extraneous factor from erectility to falling the phenomenon of folding, and lodging is the key factor that affect corn yield and quality, according to statistics, lodges and causes the corn underproduction 15%～25%.Cause nearly 1,000,000 tons of the production loss of corn in China every year because of lodging.At present along with the improving constantly of maize culture level, the contradiction of dense planting and lodging, and, due to a lot of uncertain natural causes generations, cause corn lodging to cause that production loss presents the trend of aggravation.
Summary of the invention
The objective of the invention is to overcome the defect that existing sweet corn culture technique resistant to lodging exists, propose that a kind of sweet corn is resistant to lodging grows seedlings and cultivation method, adopt this method, the sweet corn plant strain growth is good, the root system development stalwartness, strengthen the sweet corn lodging tolerance, improved output and the quality of sweet corn.
The present invention is achieved by the following technical programs:
A kind of sweet corn is resistant to lodging grows seedlings and cultivation method, comprises the following steps:
1) select the loosing soil fertility preferably sandy loam add decomposed manure and mix at 5: 2 in proportion, with the Baijunling sterilization, places after 10 days the 128 Huo72Xue caves, cave of packing into and coils standby;
2) ground paving thin film, put the cave dish after dress soil on film according to the order of sequence, before broadcasting, basked seeds 1 day, and is by Pan Jiao vola, ready cave water, live by 1/cave dry seeds, the thick fine earth of lid 1～1.5cm, then cover thin film or sunshade net;
3) after seedling all sprouts, control temperature at 17～24 ℃, humidity is 62%～68%; When seedling grows to 2 leaf 1 heart, the cave dish to be mentioned, the corn seedling main root has grown approximately 2～10cm of cave tray bottom leaking hole, along the cave tray bottom, all cuts off all main roots; Seedling grows to 3 leaf 1 hearts, and the new root system in bottom stretches out cave tray bottom leaking hole approximately during 0.5～2cm again, the transplanting of going to the field;
4) transplant and start the experienced seedling that progressively ventilates the last week, transplanted first 3 days, whole day is placed in canopy by the cave dish and practices seedling outward, strengthens the resistance of seedling;
5) select the glutinous loam of crop rotation, the plot of middle fertility, nothing plantation conventional corn within 200m around land used; 7～August before cultivation, the sowing one season the green manure sweet potato;
6) 2～March of Second Year, the 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 is transplanted after 4 o'clock in the afternoon, after cultivation, waters normal root water; Adopt the plantation of duplicate rows district, after field planting, control measures are identical with conventional corn.After weaving silk, female fringe can gather in 21～24 days.
Purpose of the present invention can also further realize by following technical measures.
Aforesaid sweet corn is resistant to lodging grows seedlings and cultivation method, the high 22～28cm in ridge in wherein said step 5), row spacing 75～85cm, wide 2535cm between ridge.
Aforesaid sweet corn is resistant to lodging grows seedlings and cultivation method, spacing in the rows 33～38cm in wherein said step 7), and line-spacing 50～60cm, planting density is every mu of 3000～3500 strains.
With existing sweet corn cultivation method resistant to lodging, compare, the present invention has and grows seedlings and the advantages such as the cultivation program is easy, saving of work and time.Sweet corn root growth stalwartness, aerial root occur early, to have improved plant soil effective fertility, the penetrating ability of soil increases, and the soil weeds in field significantly reduces, and weeds fresh weight amount reduces by 80%, the sweet corn product quality obviously improves, and output improves 15～20% than traditional cultivation.The method that the present invention adopts seedling to be completely cured, reduce root soil humidity, promote the premature eruption that reaches of lateral root and aerial root, improve root system total amount 10～25%, the root system development stalwartness, the plant base portion rugosity cultivation plant base portion rugosity of more not being completely cured increases thick approximately 0.5～2.0cm, has strengthened the lodging tolerance of sweet corn.The present invention has adopted sowing sweet potato green manure, turns over into field, in conjunction with the method for plastic mulching, makes Soil Available potassium recruitment reach 80. 8 of green manure burst size～88. 5%, has improved recycling of potassium, promotes the stalwartness growth of sweet corn root system and plant.The sweet potato salt tolerance effects is fairly obvious, and its effect reaches 80% left and right, promotes the equilibrium utilization of soil nutrient, for new way has been opened up in sweet corn cultivation resistant to lodging.
Advantage and disadvantage of the present invention, will make an explanation by the non-limitative illustration of following preferred embodiment, and these embodiment only provide as an example.
Embodiment
The invention will be further described below in conjunction with the embodiment of " Hua Zhen " sweet corn.
The present embodiment comprises the following steps:
1) select the loosing soil fertility preferably sandy loam add decomposed manure and mix at 5: 2 in proportion, with the Baijunling sterilization, places after 10 days 128 caves, cave of packing into and coils standby.
2) ground paving thin film, put the cave dish after dress soil on film according to the order of sequence, before broadcasting, basked seeds 1 day, and is by Pan Jiao vola, ready cave water, live by 1/cave dry seeds, the thick fine earth of lid 1～1.5cm, then cover thin film or sunshade net.
