Abstract

The invention provides a carrot seed germination accelerating method. The carrot seed germination accelerating method comprises the following steps of selecting seeds; soaking the seeds by using a seed soaking agent; soaking the seeds by using microwave nutrient solution; storing the seeds in a refrigerator at variable temperatures; mixing rare earth in the seeds; and performing seed germination acceleration. By the carrot seed germination accelerating method, a period of dormancy of the seeds is broken, the germination speed is high, heights of germinated seedlings are in order, the seedlings are strong, the content of trace elements is high, carbosulfan, maleic hydrazide, thiamethoxam, kinetin (KT) and the like are added in the seed soaking agent, a seed germination accelerating effect is achieved while a sterilizing effect is achieved, and pest and disease damage of a field is little after the seedlings are transplanted.

Description

A kind of Carrot Seed germination accelerating method

Technical field

The present invention relates to field of vegetable, be specifically related to a kind of Carrot Seed germination accelerating method.

Background technology

A lot of vegetable seeds needs vernalization, and the general seed of vernalization that needs can be divided into two classes: a class is that fruit vegetables seed sprouting is slow, needs to urge kind, as tomato, capsicum, eggplant, cucumber; An other class is that summer temp is high, causes germination rate of vegetable seeds low, so also need to urge kind, as asparagus lettuce, carrot, carrot, garlic.Different vegetables, respective vernalization mode is different.Hang well method, refrigeration, mix micromicrofarad etc.Different vernalization modes, corresponding different vegetable seeds.Before general vernalization, first through seed selection, sterilization, seed soaking, finally to be only vernalization.Conventional germination accelerating method can improve percentage of seedgermination, shortens germination time, alleviates Field diseases, and seedling seedling is neat, Miao Zhuan.But existing germination accelerating method does not all have the nutrient component that can improve vegetables, improve the quality of vegetables further.

Summary of the invention

The invention provides a kind of Carrot Seed germination accelerating method, this germination accelerating method can not only improve percentage of seedgermination, alleviates Field diseases, seedling seedling is neat, Miao Zhuan, improve output, add the nutrient composition content of carrot simultaneously, further increase the quality of carrot.

The technical solution used in the present invention is:

A kind of Carrot Seed germination accelerating method, is characterized in that, comprise the following steps:

(2) seed soaked is put into the container filling nutrient solution again to soak, container is put into 600w microwave equipment, the firepower microwave treatment with 60% 10 seconds-20 seconds, then stops microwave treatment, soaks 5-6 hour again under taking out normal temperature;

(3) clean with clear water again;

(4) bound up with gauze by above-mentioned soaked seed, squeeze and remove portion of water, put into refrigerator at 4-5 DEG C of refrigeration 10-12 hour, then pull out to enclose with gauze and put into presprouting of seeds case, at 20-25 DEG C, constant temperature vernalization 24-36 hour, takes out;

(5) seed after constant temperature vernalization is being mixed thoroughly with rare earth, concrete grammar is for after joining 3-4g rare earth and stirring in 40-50g water, add 2.5-3.5kg seed, fully mix thoroughly, then seed and fine earth are mixed thoroughly by the weight ratio of 1:3, are seeded in seedbed according to a conventional method, mulching straw, spray permeable again, within general 3-4 days, can germinate.

Described Carrot Seed germination accelerating method, is characterized in that:

Nutrient liquid described in step (2) is formulated by following component; often liter of nutrient solution comprises the component of following weight: borax 0.3-0.5g, ammonium molybdate 0.2-0.3g, ZnSO47H2O 0.2-0.5g, cupric sulfate pentahydrate 0.2 ~ 0.4g, vitamin B1 0.02-0.03g, vitamin c 1-2g, taurine 0.3-0.5g, vitamin D 2-5mg, vitamin E 0.4-0.7g, ferrous gluconate 2-4g, surplus is water.

In seed soaking agent of the present invention and nutrient liquid, water insoluble active ingredient can adopt water soluble preparation to be added to the water dissolving again.

Beneficial effect

Germination accelerating method of the present invention, break the resting stage of seed, germinate fast, the height of seedling degree of germination is neat, Miao Zhuan, micronutrient levels is high, carbosulfan, maleic hydrazide, Diacloden, kinetin KT is added in seed soaking agent, etc., while playing sterilization, urge into seed sprouting, after seedling replanting, field damage by disease and insect is few.Germination rate can improve 6-12%, and germinating to seedling rate reaches more than 95%.Germination period can shift to an earlier date 1-2 days.
