Description
Technical field
The invention belongs to agricultural plantation technology field, the mating system of more particularly to a kind of pawpaw seed and pawpaw seedling are special
Use fertilizer.
Background technology
Pawpaw, rose family Chaenomeles, shrub or dungarunga, fruit oblong, dark yellow are wooden, taste fragrance, carpopodium
It is short, there is deeper fold after cause and effect reality dry processing, be commonly called as wrinkled papaya, be mainly distributed on Jiangsu, Henan, Shandong, Anhui, Zhejiang
River, Hebei, the ground such as Guizhou.Wrinkled papaya is《Chinese Pharmacopoeia》The medicinal Chaenomeles Cultivars that version one in 2010 is recorded, main pharmacological
The composition of effect such as flavones, organic acid, terpenoid etc..Pharmacological experiment study shows, the fruit extract of pawpaw platymiscium
With the effect such as antitumor, anti-oxidant, anti-inflammatory and antalgic, antibacterial, hypoglycemic, reducing blood lipid, pawpaw is also national health State Family Planning Commission batch
Accurate medicine-food two-purpose kind.
Pawpaw is often seed seedling-raising method, cuttage, planting of layer etc. with propagation method, though the method for inserting, the planting of layer are conventional numerous
Method is grown, production is mainly thought based on seed seedling-raising method, the need for seed seedling-raising method can meet large-scale plantation.The kind of pawpaw
Sub- seedling method breeding is often after air-drying storage after fruit maturation, Second Year takes kind of a sowing, or seed sand storage is passed the winter, and Second Year takes
Go out to sow in spring.The germination percentage of conventional seed seedling-raising method seed is not high, and pawpaw seedling preference temperature is fast to be grown at 16~30 DEG C, low temperature
Under it is slow-growing, cultivation period is longer, and Guizhou province spring day and night temperature is big, 2 4~11 DEG C of monthly mean temperatures, 3 monthly average gas
8~16 DEG C of temperature, less than 5 DEG C or to run into the tender wooden seedling of freezing temperature children easily dead.
Pawpaw seedling is more sensitive to fertilizer, and sufficient nitrogenous fertilizer can promote tender shoots pumping, seedling fast-growth, stalk thick
Strong, well developed root system etc..Traditional sulfur-bearing composite fertilizer is difficult to the demand for meeting pawpaw seedling development, not only needs repeatedly to apply root
Portion applies fertilizer, and tender shoots and blade face are also required to spray the fertilizer such as trace element, causes the cost for planting pawpaw very high, the use of fertilizer
Directly influence growing for pawpaw seedling, and the cost and yield planted.
The content of the invention
The invention provides a kind of mating system of pawpaw seed and a kind of pawpaw seedling dedicated fertilizer, to solve background skill
The problem of being proposed in art.
The present invention is achieved through the following technical solutions：
A kind of mating system of pawpaw seed, comprises the following steps：
(1) annual December, the seed that the bud embryo that Tibetan no disease and pests harm is done then is full is scalded with 45~55 DEG C of water
Kind, after natural cooling, sterilized with 10~20h of medicining liquid dipping；
(2) thin river sand or plant ash etc. and one piece of the seed crossed with medicining liquid dipping are rubbed, and seed is placed in clear water and washed
Decontamination liquid；
(3) by weight 1：After 4 ratio and thin river sand are puddled uniformly, uniformly it is deposited in room ventilation and gives shade place, and cover
Upper stalk layer, sand storage is passed the winter；
(4) 2~March of spring is treated, is had after 65%~75% seed breach shows money or valuables one carries unintentionally, you can sowing；
(5) 22~25cm of line-spacing is pressed on the seedbed of sowing, opens the ditch that depth is 5~10cm, seed is pressed 3~5cm strain
Away from being spread in ditch, earthing is watered, and 15~30 DEG C of insulation is emerged；
(6) every mu with 5~7kg is planted, and can be emerged within 12~15 days or so after broadcasting, be loosened the soil after emerging, weeding, waters and apply
Fertilizer, 1~2cm of height of seedling applies fertilizer once, and 5~6cm of height of seedling refertilizes once, and every mu of fertilising consumption is that 4~6kg is applied for every mu every time every time
4~6kg of fertilizer, promotes seedling growth, can be transplanted seedlings during height of seedling 10cm.
It is preferred that, the thimerosal described in step (1) is：3%~8% white aqueous slkali；
It is preferred that, step (5) the heat and moisture preserving condition is to cover film either greenhouse closed environment, thin temperature in the shed
15~25 DEG C of scope, canopy temperature is at 16~30 DEG C.
Pawpaw seedling dedicated fertilizer, is made up of the raw material of following parts by weight：173~183 parts of bran chaff, MAP 161~
171 parts, 133~143 parts of potassium sulfate, 491~501 parts of urea, 1.9~2.1 parts of compound sodium nitrophenolate, calcium, magnesium, iron, manganese, zinc, copper and
18~22 parts of the ethylenediamine tetra-acetic acid chelate of molybdenum.
It is preferred that, the pawpaw seedling dedicated fertilizer is made up of the raw material of following parts by weight：178 parts of bran chaff, MAP

DEG C hot water is 1 according to mass ratio:100~1:150 ratio is diluted；
(3) pawpaw seedling dedicated fertilizer is obtained through drying, screening and cooling.
Beneficial effect：The mating system of the pawpaw seed, is incubated using film and greenhouse, shortens the germination of pawpaw
In the cycle, the germination percentage of pawpaw seed is improved, the germination percentage of seed is high, breed that the time is short, seedling growth is healthy and strong, and survival rate is high, can
The need for meeting large-scale plantation.The pawpaw seedling dedicated fertilizer, is root fertilizer, is not required to blade face and applies spray fertilizer material, its nitrogen
Rich content, mainly exists in the form of urea state nitrogen, and this is with can quickly meet the pawpaw seedling development phase to fertilizer especially
It is the demand to nitrogen, the trace element contained exists with EDTA Chelating states, and stability is high, it is to avoid produce antagonism effect with P elements
Should, it can effectively be absorbed by plant, reduce the generation of physiological disease, the compound sodium nitrophenolate contained, which has, accelerates pawpaw growth of seedling hair
Educate, effect of promoting root growth strong sprout, pawpaw seedling dedicated fertilizer of the present invention can effectively reduce cost, improve the matter of pawpaw seedling
Amount.
