Description
Technical field
The present invention relates to technical field of agricultural cultivation, it is specifically a kind of improve Flemingia philippinensis seed-setting rate and grain weight
Method.
Background technology
Seed is the material base of Chinese medicine Flemingia philippinensis production, and it is to increase seed production to improve seed-setting rate and grain again
One of effective way of amount and high-quality introduces a collection stablize the important leverage of supply.In its large area seed production at present, mainly exist
The flower pod phase prevents different types of pest to organ of multiplication harm using different agents are periodically sprayed；Increase harvesting number, to carry
Its high setting percentage and seed production.But it since the flower pod phase of its Flemingia philippinensis is longer, sprays often, leads to spray harvesting work amount
Greatly, seed production cost is high；Also Site environment is caused centainly to pollute simultaneously；Since this method mainly passes through chemical prevention means
Increase seed production with picking time is extended, solves the influence that external biotic factor produces seed to a certain extent, but
It is not directed to the reproductive characteristic of plant itself, colored pod phase seed maturity is improved with the ancillary techniques such as chemical regulation and measure
Regularity, setting percentage and grain weight further increase its seed unit yield.
Invention content
Flemingia philippinensis generative growth phase is several due to being influenced to set seeds with itself fruit pod by its flower pod phase pod bearing habit
Limitation, causes Grain Ripening degree inconsistent, the maturity period is long, and harvesting standard differs；In addition seed maturity day temperature is higher, kind
Son is easy to nature and bursts, and falls off, while there is also fruiting period Pests Damage is serious, causes setting percentage relatively low and seed production is horizontal
Decline.The problem of present invention gives birth to feature and be primarily present for the Flemingia philippinensis flower pod phase, targetedly uses cultivation technique
Measure and agronomy means improve its setting percentage and grain weight, further increase its yield, and method is as follows：
A method of Flemingia philippinensis seed-setting rate and grain weight being improved, field planting management to Flemingia philippinensis enters
The flower pod phase, which is characterized in that include the following steps：(1) flower pod initial stage sprays paclobutrazol, a concentration of 50~150mg/l, and fine day connects
Continuous spray 3 times；(2) flower pod mid-term, each fruit pod set seeds number when being 1~2, spray blade face Water soluble fertilizer；(3) flower pod later stage topping.
Further, it is that fine day continuously sprays 3 times afternoon that the step (1), which spends pod initial stage to spray the paclobutrazol time,.
Further, step (1) the flower pod initial stage sprays a concentration of 50mg/l of paclobutrazol, due to tendril pod phase nutrition
Growth is synchronous with reproductive growth, causes fruit pod maturity to differ, the length of the internode for the section that bears pods is controlled using paclobutrazol；Suppression
Nutrient growth processed promotes photosynthate to be converted to reproductive growth center, at initial stage beginning, sprays low concentration paclobutrazol
(50mg/L), fine day continuously spray 3 times, can inhibit its nutrient growth, ensure the fruit pod maturity of same inflorescence development afternoons,
Be conducive to improve maturity period photosynthate to the reproductive organs rate of transform, the weight of seed can be dramatically increased to a certain extent
And maturity；Fruit pod is also allowed for simultaneously concentrates harvesting, less harvesting number.
Further step (2) flower pod mid-term, sprays the Water soluble fertilizer a concentration of 0.15% on blade face, is continuously sprayed afternoon in fine day
It applies 3 times, for the Flemingia philippinensis flower pod phase up to 2-3 months, it is 1-2 that each fruit pod, which is set seeds and counted, with the easy aging of late growth
The characteristics of with easily bursting naturally after seed maturity, using the growth for spraying the Foliar Spraying regulation and control flower pod phase in the flower pod phase, anti-morning
It declines and is burst with seed, improve seed-setting rate and yield, the outer fertilizing type of plant roots not only contributes to improve its later stage photosynthetic work
With promotion grows and prevent anaphase blade early ageing；The setting percentage of seed can be significantly improved simultaneously and increases the degree of saturation of seed.
Further, step (2) the flower pod mid-term, the Water soluble fertilizer for spraying blade face are that boron fertilizer, potash fertilizer, boron fertilizer and potash fertilizer are mixed
Close liquid.
Further, the boron fertilizer is potassium dihydrogen phosphate (purity >=96%)；The potash fertilizer be polymerization Boratex (purity >=
99%).
Further, the step (3) flower pod later stage Topping Time is its number of blade up to 18~22 or the section number that bears pods
When reaching 5~6, since Flemingia philippinensis picking time is long, harvesting is secondary more；The flower pod later stage is influenced by low temperature overcast and rainy day weather, fruit
Pod maturity differs, and setting percentage significantly reduces, to reduce influence of the flower pod later stage adverse environmental factors to seed-setting, after guarantee
The abundant sexal maturity of seed that phase bears pods, less harvesting number and raising prometaphase improve seed quality.The pod later stage is being spent,
The number of blade is up to 20 or when the section number that bears pods reaches 5-6, is made a return journey apical dominance by this agronomic measures of pinching, promotes the later stage
The development of inflorescence and the effective fruit pod number of raising, maturity, ensure that seed is fully ripe, are conducive to later stage disposably harvesting and harvesting
The amount of labour used is reduced, and is significantly improved setting percentage and grain weight, is further increased yield.
Further, singling covers nylon net bag afterwards for the step (1), (2), (3).
Further, field planting line-spacing 25cm, spacing in the rows 10cm, the kind per cave 2-3, per 2 plants of cave.
Compared with prior art, the beneficial effects of the present invention are：Present invention combination Flemingia philippinensis spends the pod phase main
Problem and fruit pod Mature property, it is comprehensive using " exoroot nutrition "+" chemistry in conjunction with " preceding control, middle benefit are beaten afterwards " seed production model
The regulation and control "+method of " agronomic measures ", overcome the influence of extraneous adverse environment and cause kernel maturing and degree of saturation it is inconsistent and
The limitation of itself fruit pod Grain-Filling Characteristics further increases seed production to improve the seed-setting rate and grain weight of Flemingia philippinensis
It is horizontal.This method has the advantages that following aobvious：(1) setting percentage can be significantly improved, seed-setting rate is improved to 77,5% using method,
Setting percentage than control (CK) can improve 7-8 percentage points；(2) grain weight is dramatically increased, with the method, Flemingia philippinensis thousand
It can increase by 7.32% than control again；(3) be conducive to the raising of fruit pod maturity, the later stage concentrates disposable harvesting, shortens harvesting week
Phase；(4) be conducive to, to increase seed production, reduce harvesting number, save seed production cost, reduce to the unfavorable of ecological environment
It influences, further affects the yield and quality of seed.
Specific implementation mode
