Abstract
The invention relates to the agricultural technique field, in particular to a culture method for mulching and culturing seedling of earthnuts. Corn straw is pretreated, seeds are upright sowed in thecavernous body of the corn straw, the sowing depth is 1cm, the corn straw is buried in the soil vertically, and the top part of the corn straw is covered with soil for culturing seedling. The corn straw is used for substituting a fiber container, thereby solving the problems existed in the traditional seedling culturing method that the root is broken, labor and time are wasted, the fiber containeris easy to crash, etc., realizing the non-damaged root seedling culturing and transplanting, eliminating the seedling reviving g stage, culturing the sound seedling, and improving the output.
Description
Technical field
The present invention relates to agricultural technology field, a kind of specifically root-protecting seedling raising cultivation method.
Background technology
When the tradition peanut is grown seedlings, be about a high 10cm diameter 4-5cm of paper, the paper web of one end back cover, paper web is filled up with the moderate fine earth of humidity, and seed is broadcast in paper web, 2 seeds of each paper web, seed level 1cm, dig a hole that the degree of depth is identical with the paper web height then on the limit, plot that will transplant, the paper web of broadcasting seed evenly is placed in the hole, the even moderate fine earth of cladding thickness 2cm humidity on the paper web, covered with plastic film above last keeps moisture.If summer high temperature, lid layer weeds or crops straw shade above film.When the soil of peanut seedling top, the paper web of being with seedling is moved on to the field transplant.But take this seedling raising manners to grow seedlings, the one, peanut seedling is completely cured seriously when transplanting, and the back seedling of transplanting seedlings needs the long time just can restore normal growth, and transplanting seedling time is long.The 2nd, paper web is made trouble, and is time-consuming, and paper web is easily broken in the process of transplanting seedlings.
Summary of the invention
At above-mentioned situation, the invention provides a kind of root-protecting seedling raising cultivation method, replace paper web with maize straw, solve that traditional seedling method exists be completely cured, problem such as time-consuming, the easy fragmentation of paper web, realize harmless root system seedling raising and transplanting, eliminate the seedling-slowing stage after transplanting, cultivate strong sprout, improve output.
Root-protecting seedling raising cultivation method of the present invention mainly may further comprise the steps:
With the corn stalk preliminary treatment, seed is uprightly broadcast in the cavernous body of corn stalk, and seed level 1cm vertically imbeds corn stalk in the soil, and corn stalk top earthing is grown seedlings.
Root-protecting seedling raising cultivation method of the present invention specifically may further comprise the steps:
The corn stalk preliminary treatment may further comprise the steps: (1), corn stalk is dried; (2), corn stalk segment; Described corn stalk segment is the corn stalk of drying to be left out the beginning and the end be cut into the long section of 17-22cm; The used maize straw of the present invention preferably picks up from the part of the middle 1.5m of whole corn stalk.Its optimum length is 20cm.
(3), described corn stalk is put in the soaking solution of urea of the potassium dihydrogen phosphate that contains 3-5% and 1-2% and soaked for 1 week; Also can add an amount of carbendazim in the above-mentioned soak, carry out sterilization.
(4), per 10 of the corn stalk after the segment is tied into a bundle, seed is uprightly broadcast in the cavernous body of corn stalk, and seed level 1cm pricks corn stalk more and evenly is placed in the hole identical with corn stalk length.
Dig a hole that the degree of depth is identical with corn stalk length on the limit, plot that will transplant, will tie into a bundle, prick corn stalk more and evenly be placed in the hole through per 10 of pretreated corn stalk.Uprightly broadcast 1 seed in the cavernous body of each corn stalk, seed level 1cm, the fine earth that the usefulness humidity of cavernous body deficiency is moderate in the corn stalk is filled.The even moderate fine earth of cladding thickness 2cm humidity above corn stalk afterwards.Covered with plastic film above last keeps moisture.If summer high temperature, lid layer weeds or crops straw shade above film.Grow seedlings, transplant during the soil of seedling top.When peanut seedling when soil top, according to predetermined line-spacing, open the ditch about dark 17-22cm in the field, corn stalk that will the band seedling, per 2 is 1 cave, stand upright in the ditch, then earthing, water.
Compare with traditional paper web seedling method, the advantage of technology of the present invention is: (1) peanut is excellent at the process of transplanting root system, eliminated slow seedling process. (2) saving of work and time, the body raw material of growing seedlings are maize straw, generally must additional investment. (3) are because maize straw is with the soaked with liquid mistake that has nutritive element, cavernous body in the corn stalk is nutritious in addition, for the growth of peanut seedling provides abundant nutrition, the growth of seedling stalwartness. can be the peanut plant growth after (5) corn stalk is rotted nutrition is provided. (6) are not owing to there is tangible seedling-slowing stage, peanut is bloomed early, the result early, the result is many, prolong breeding time, output obviously increases, fate to the beginning flower after calendar year 2001s two annual in 1999 is transplanted seedlings reduces 6.3 days, 12.7 of the individual plant amount of blooming increases; The per plant number increases by 1.75; Plumpness increases by 5.2%; Pod mu increases output 30.75kg, volume increase 11.4%.
Embodiment
Further specify the present invention below by embodiment.
Embodiment 1:
(1), corn stalk dries, and rounds the part about 1.5m in the middle of the corn stalk, is cut into the long section of 20cm, is put into then in the urea liquid of the potassium dihydrogen phosphate that contains 3-5% and 1-2% to soak for 1 week, add an amount of carbendazim in the soak and carry out sterilization.
(2), dig a hole about degree of depth 20cm on the limit, plot that will transplant, per 10 of corn stalk is tied into a bundle, evenly be placed in the hole, fill with the moderate fine earth of humidity when cavernous body is not enough in the corn stalk, then seed is uprightly broadcast in corn stalk, each corn stalk is broadcast 1 seed, seed level 1cm, the even moderate fine earth of cladding thickness 2cm humidity above corn stalk afterwards, covered with plastic film above last, keep moisture, if summer high temperature, lid layer weeds or crops straw shade above film.
(3), when peanut seedling when soil top, according to predetermined line-spacing, open the ditch about dark 20cm in the field, corn stalk that will the band seedling, per 2 is 1 cave, stand upright in the ditch, then earthing, water.
The method of the invention is to the influence of peanut seedling, by following data imbody.
