Abstract
The invention relates to the field of a facility agriculture production planting technology, and in particular relates to a soilless culture muskmelon segmented fertilization method. According to the method, the dosage of a fertilizer is calculated according to mmol/L; the fertilization period comprises tendril elongation period, fruit setting period, fruit expansion period and fruit ripening period. The method has the beneficial effects that segmented fertilization method is in accordance with the nutrient demand law of muskmelons, the yield of the muskmelons is effectively increased and the quality of the muskmelons is effectively improved, the utilization rate of the fertilizer is further improved, and production and income are both increased.
Description
Technical field
The present invention relates to industrialized agriculture production planting technology field, particularly a kind of soilless culture muskmelon segmented fertilizing method.
Background technology
Muskmelon is nitrophilous potassium crop, and to the demand of nitrogen potash fertilizer, much larger than phosphate fertilizer, muskmelon fertility is larger to the absorptive amount of nitrogen early stage, and the fertility middle and later periods is large to potassium element demand, and therefore the rational proportion of nitrogen potash fertilizer is supplied with particularly important.In the conventional production of muskmelon, understood and executed nitrogen potash fertilizer more at present, but amount of application and proportioning are not scientific and reasonable.In muskmelon soilless culture, problem is particularly outstanding, and nitrogen, potassic fertilizer consumption and fill a prescription unreasonablely will cause nutritional deficiency or excessive phenomenon, directly affect yield and quality, and cause fertilizer to waste the problems such as even environmental pollution.Especially in muskmelon Winter Cultivation process, breeding time is longer, according to the different vegetative stages of muskmelon, the demand rule of fertilizer is shown to best segmented fertilizing method is most important.
Summary of the invention
The present invention is directed to the problem of above-mentioned existence, a kind of soilless culture muskmelon segmented fertilizing method is provided.Fertilizing method, according to muskmelon growth characteristics, utilizes soilless culture substrate plantation muskmelon in green house.
The present invention for the technical scheme that its technical problem of solution adopts is:
Fertilizing method is by the segmentation realization of applying fertilizer, and concrete steps are as follows:
In the present invention, fertilizer amount calculates with mmol/L, and fertilizing time is divided into: stretch climing phase, the phase of bearing fruit, fruit expanding period, fructescence.
A kind of soilless culture muskmelon segmented fertilizing method, is characterized in that, carry out segmented fertilizing management according to the different times of facility muskmelon soilless culture, the step of above-mentioned fertilizing method is as follows:
(1) base manure is used: the cultivation matrix of having loaded applies fertilizer 26kg/m
3mix thoroughly;
(2) stretch the fertilising of climing phase: 7 days, start fertilising from muskmelon transplantation of seedlings, join fertile ratio and be: N:P:K=1:0.08:0.38; In mmol/L, join fertile amount and be: N+P+K=20.97 ~ 25.63mmol/L, frequency of administration is: 1 day 1 time;
(3) phase of bearing fruit applies fertilizer: at this moment muskmelon changes to reproductive growth from nourishing and growing, and for bearing fruit smoothly, need prune and prune in time, and reduce the fertile amount of application of N, bears fruit approximately 7 days from pollinating to, join during this time fertile ratio to be, and N:P:K=1:0.1:0.46; In mmol/L, fertile amount is: N+P+K=18.27 ~ 22.33mmol/L, and frequency of administration is: 1 day 1 time;
(4) fruit expanding period fertilising: start from melon fruit is beared fruit, join fertile ratio and be, N:P:K=1:0.1:0.69; In mmol/L, join fertile amount and be: N+P+K=20.97 ~ 25.63mmol/L, frequency of administration is: 1 day 2 times;
(5) fructescence: after expanding stage finishes, for improving the content of muskmelon soluble solid, joining fertile ratio be N:P:K=1:0.1:0.92; In mmol/L, join fertile amount and be: N+P+K=23.67 ~ 28.93mmol/L, frequency of administration is: 1 day 1 time.
In above-mentioned steps (1), fertilizer used is Chicken dung.
In above-mentioned steps (2), N fertilizer used is nitrate of lime, potassium nitrate, sodium nitrate; P fertilizer is ammonium dihydrogen phosphate (ADP); K fertilizer is potassium nitrate.
In above-mentioned steps (3), N fertilizer used is nitrate of lime, potassium nitrate; P fertilizer is ammonium dihydrogen phosphate (ADP); K fertilizer is potassium nitrate.
In above-mentioned steps (4), N fertilizer used is nitrate of lime, potassium nitrate; P fertilizer is ammonium dihydrogen phosphate (ADP); K fertilizer is potassium nitrate, potassium sulfate.
In above-mentioned steps (5), N fertilizer used is nitrate of lime, potassium nitrate; P fertilizer is ammonium dihydrogen phosphate (ADP); K fertilizer is potassium nitrate, potassium sulfate.
The required trace element of muskmelon is sprayed supplementary by foliage fertilizer.
The fertilizer ratio following (table 1) in concrete each period:
Table 1: the concrete fertilizing amount of different times (mmol/L)

The invention has the beneficial effects as follows:
1, after above-mentioned processing, muskmelon is all good than untreated in each period of growing, and can promote nourishing and growing of muskmelon, makes tendril can more early reach the joint position of pinching.Can balanced nutrients growth and reproduction the relation of growth, fruit-setting rate is increased.Can improve muskmelon single fruit weight, further improve the per mu yield of muskmelon, can also increase the soluble solid content of muskmelon.
2, fertilizing method is analyzed according to the data that obtain in test, has drawn the optimum fertilizing amount growing period in muskmelon difference, has grasped the nutrient uptake feature of muskmelon, accomplishes accurate applying fertilizer, improves utilization rate of fertilizer, reduces the wasting of resources and environmental pollution.
Above-mentioned segmented fertilizing method meets muskmelon nutrient demand rule, effectively improves output and the quality of muskmelon, further improves the availability of fertilizer, realizes increasing both production and income.
