Abstract
The invention discloses an alfalfa fertilizing method. The method comprises the following steps: performing first round of fertilization on alfalfa when alfalfa turns green and grows to reach a height of 15-30 centimeters; performing second round of fertilization on the alfalfa when the alfalfa is mown for the first time and grows to reach the height of 15-30 centimeters; performing third round of fertilization on the alfalfa when the alfalfa is mown for the second time and grows to reach the height of 15-30 centimeters, wherein in the first, second and third rounds of fertilization, applied fertilizers are all yeast-source organic fertilizers and growth-period inorganic fertilizers, the fertilization amounts of the yeast-source organic fertilizers are all 5-20kg/mu, and the fertilization amounts of the growth-period inorganic fertilizers are all 5-20kg/mu; and performing fourth round of fertilization on the alfalfa after alfalfa is mown for the third time under the conditions that the applied fertilizers are the yeast-source organic fertilizer and an overwintering formula inorganic fertilizer, wherein the fertilization amount of the yeast-source organic fertilizer is 5-10kg/mu, and the fertilization amount of the overwintering formula inorganic fertilizer is 3.33-10kg/mu. By performing the fertilization by using the alfalfa fertilizing method disclosed by the invention, planted alfalfa is low in fertilization cost input, and can also be used for increasing the yield.
Description
Technical field
The present invention relates to fertilizing method, particularly relate to a kind of fertilizing method of alfalfa.
Background technology
Current vast Alfalfa Growing enterprise chemical fertilizer usage amount is large, and drop into more, fertilizer ratio is unreasonable, fertilization mode is science not, and the fertilizer amount material of input is large, and every mu of fertilising average input is 260 ~ 350 yuan, but alfalfa output is lower, every mu of average yield is 450 ~ 750kg.
Summary of the invention
The present invention aims to provide a kind of fertilizing method of alfalfa, to improve the output of alfalfa.
Alfalfa fertilizing method of the present invention is as follows:
When clover turns green and grows into 15 ~ 30 centimeters, carry out first round fertilising;
Clover first time cradle after and grow into when 15 ~ 30 centimeters, carry out second and take turns fertilising;
Clover second time cradle after and grow into when 15 ~ 30 centimeters, carry out third round fertilising;
What described first round fertilising, second took turns that fertilising and third round fertilising apply include yeast source organic fertilizer and vegetative period inorganic fertilizer, yeast source organic fertilizer is often taken turns and is used 5 ~ 20kg/ mu, and generation inorganic fertilizer is often taken turns and used 5 ~ 20kg/ mu;
After third time cradles, carry out fourth round fertilising, the fertilizer of applying comprises yeast source organic fertilizer and formula inorganic fertilizer of surviving the winter, and yeast source organic fertilizer uses 5 ~ 10kg/ mu, and formula inorganic fertilizer of surviving the winter uses 3.33 ~ 10kg/ mu.
Preferably, in order to fertilizer can be made better to be absorbed by alfalfa, fertilising is taken turns in described first round fertilising, second, third round fertilising is carried out respectively at twice, and twice fertilising is respectively 7 ~ 10 days interval time.
Preferably, in order to provide more rational proportion and nutriment fully, described yeast source organic fertilizer N P and K total content 10wt% (wt% to the growth of alfalfa, mass percentage, lower with) more than, more than content of organic matter 60wt%, effective total viable count 0.2 hundred million/gram more than.
Preferably, in order to the inorganic fertilizer providing more rational proportion to the growth of alfalfa, when more can generate with applicable alfalfa, required element adapts, described vegetative period inorganic fertilizer by mass N-P-K content proportioning be N:P
2o
5: K
2o=(8 ~ 14): (18 ~ 22): (19 ~ 26).
Preferably, in order to the inorganic fertilizer providing rational proportion to the growth of alfalfa, and be more conducive to the safe overwintering of alfalfa in winter, described in survive the winter formula inorganic fertilizer by mass N-P-K content proportioning be N:P
2o
5: K
2o=(5 ~ 6): (19 ~ 22): (22 ~ 26).
Preferably, in order to obtain higher input-output ratio, fertilising and third round fertilising are taken turns in described first round fertilising, second, and in the fertilizer of applying, yeast source organic fertilizer uses 6 ~ 15kg/ mu for every wheel, and inorganic fertilizer total amount was often wheel and used 6 ~ 15kg/ mu vegetative period.
Preferably, in order to obtain higher input-output ratio, described fourth round fertilising, in the fertilizer of applying, yeast source organic fertilizer uses 6 ~ 10kg/ mu, and formula inorganic fertilizer of surviving the winter uses 6 ~ 10kg/ mu.
Preferably, in order to make alfalfa absorb more fully fertilizer, be more conducive to the growth of alfalfa, twice fertilizing amount that fertilising and third round fertilising are taken turns in described first round fertilising, second is identical.
Alfalfa fertilizing method of the present invention, by conservative control Fertilizer Type, fertilizing amount, fertilizer application frequency and fertilization time, compared with adopting the alfalfa of traditional fertilization mode, makes the output of alfalfa add 15 ~ 30%.In addition, compared with the fertilization mode of traditional alfalfa, the input of every mu also reduces, and improves input-output ratio.
