Abstract
The invention provides a pregermination method of potato in early winter, comprising the steps of processing potato, pregerminating, and slicing. The pregermination method is characterized by comprising the following steps: (a) potato seed processing: putting a potato seed into mixed liquor of 700-900 times of liquid of 58% of metalaxyl and gibberellin with concentration of 1-2 ppm at the volume ratio of 1:1, and dipping for 2-5 minutes; (2) pregermination: carrying out circumcision on processed potato seed by 3/4 near the terminal bud, putting on a wet straw, stacking 3-4 layers according to the principle that straw and potato are alternately arranged, covering by a film or a sack, and stopping pregermination when the length of the bud is 2-3 cm; and (3) slicing: slicing the pregerminated potato seed by a sterilized tool according to the specification of 30-40g of rhombic bisphenoid, wherein each rhombic bisphenoid has one bud; sterilizing the tool again after used for 10 minutes or when the tool cuts diseased and rotten potatoes; and naturally drying the sliced potato blocks until wound surface is suberized, and sowing. The invention can effectively lower potato consumption amount, prevent cross infection of germs (virus), lower rotten potato rate and improve rate of emergence.
Description
Technical field:
The present invention relates to a kind of winter germination accelerating method of potato early.
Background technology:
Vernalization is the winter key link of potato planting early before the potato sowing, and the winter vernalization of potato early at present mainly contains two kinds of whole potato vernalization and stripping and slicing vernalization.Whole potato vernalization mashed potato in the vernalization process is few, field emergence rate height, and protection effect is obvious, but sowing quantity is big.Stripping and slicing vernalization can be saved potato seed, and helps breaking apical dominance, and it is fast to sprout, but existing stripping and slicing technology mostly is and cuts back vernalization and plant, and the cross-infection of germ (poison) easily, potato piece moisture content run off, and cause part potato piece can not germinate even mashed potato.
Summary of the invention:
Purpose of the present invention overcomes above-mentioned deficiency, a kind of effective reduction potato seed consumption is provided, prevent germ (poison) cross-infection, reduce mashed potato rate, winter of improving emergence rate germination accelerating method of potato early.
This invention is achieved in that and comprises potato seed processing, vernalization, stripping and slicing, it is characterized in that:
1. potato seed is handled
Place 700～900 times of liquid of 58% metalaxyl and 1～2ppm concentration gibberellin to soak 2～5 minutes seed potato by the mixed liquor of 1: 1 volume ratio.
2. vernalization
The seed potato of handling is used cutter ring cutting 3/4 near terminal bud, be placed on the straw that soaked, press one deck straw one deck potato and stack 3～4 layers, cover with film or gunnysack at last, stop vernalization when bud grows to 2～3cm.
3. stripping and slicing
Press the specification stripping and slicing of 30～40g rhombic bisphenoid with the cutter of sterilizing through the seed potato of vernalization, a bud is with in every assurance, the every use of cutter is maybe sterilized when switching to disease, mashed potato after 10 minutes again, and the potato piece natural air drying that cuts is to hindering sowing in time after the face suberification.
The present invention is the potato seed vernalization technology of stripping and slicing after a kind of first vernalization, reduced 50～60% with the potato amount than whole potato vernalization sowing, vernalization process potato piece cut wound face is little, effectively prevented germ (poison) cross-infection, reduced mashed potato rate, the seed potato of handling is used cutter ring cutting 3/4 near terminal bud, shunting potato piece nutrition and growth hormone are carried to lateral bud, prevent terminal bud excessive growth, thereby promote the sprouting and the growth of lateral bud, whole potato piece is sprouted evenly.
Embodiment
1. potato seed is handled
Under the condition of about 20 ℃ of temperature, place 800 times of liquid of 58% metalaxyl and 1～2ppm concentration gibberellin to soak 2～5 minutes potato seed by the mixed liquor of 1: 1 volume ratio.
2. vernalization
The seed potato of handling is used cutter ring cutting 3/4 near terminal bud, shunting potato piece nutrition and growth hormone are carried to lateral bud, prevent terminal bud excessive growth, thereby promote the sprouting and the growth of lateral bud, and whole potato piece is sprouted evenly.The seed potato of ring cutting is placed on the straw that soaked, and presses one deck straw one deck potato and stacks 3～4 layers, covers with film at last and preserves moisture to heat, and stops vernalization when bud grows to 2～3cm.
3. stripping and slicing
Press the specification stripping and slicing of 30～40g rhombic bisphenoid with the cutter of sterilizing through the seed potato of vernalization, a bud is with in every assurance, the every use of cutter is maybe sterilized when switching to disease, mashed potato after 10 minutes again, and the potato piece natural air drying that cuts is to hindering sowing in time after the face suberification.
Claims (1)
