Abstract

The invention relates to a seed production method, in particular to a method for producing hybrid mulberry seeds, which belongs to the technical field of crop processing. Clean mulberry seeds without impurities are obtained by adopting the measures of selection of loose, fertile and sunny sand soil, soil preparation, seedling raising, field planting of parents, fertilizer application, disease and insect prevention and control, and the like, and are cultivated and popularized by farmers, so the method increases the yield of mulberries, and satisfies the needs of the market at the same time of increasing the economic incomes of the farmers.

Description

Hybridization mulberry seed producing method for seed

Technical field

The present invention relates to a kind of producing method for seed, be specifically related to a kind of hybridization mulberry seed producing method for seed, belong to the crops processing technique field.

Background technology

Mulberries are a kind of wild fruits, be grown in the country wild country, nobody shows any interest in for a long time, people pay attention to the development and use for wild fruit in recent years, find that after deliberation mulberries have very high nutritive value, pulp is rich in multivitamin and trace element, evident in efficacy for blood-supplementing blood-nourishing, often eat and can improve the human immunological competence, but its growing environment is relatively poor, output is very low, can't satisfy the demand in market.

Summary of the invention

The objective of the invention is for overcoming above-mentioned the deficiencies in the prior art part, a kind of hybridization mulberry seed producing method for seed is provided, select loose, fertile sun-drenched sandy soil earth by adopting, put in order ground, grow seedlings, measures such as field planting parent, fertilising, the extermination of disease and insect pest obtain clean pure mulberry seed, cultivation is promoted through peasant household, mulberries output is improved, when improving the household economy income, also satisfied the demand in market.

The present invention realizes with following technical scheme: a kind of hybridization mulberry seed producing method for seed is characterized in that: this method comprises whole ground, field planting parent, field planting method, fertilising, the extermination of disease and insect pest etc., specifically carries out as follows:

(1) wholely: soil is shone in the 30d deep ploughing before the plantation, by every strain 3kg, promptly every mu (1 mu=1/15ha) 1.5-2t pig manure or chicken manure, prepare enough base fertilizer, use after adding 5% (every mu of 150kg) fused calcium magnesium phosphate stack retting 7-10d, plant preceding 3-5d hack, press line-spacing 1.3m, dark 0.3m opens the plantation ditch;

(2) field planting parent: a) plantation density: spacing in the rows 85cm, line-spacing 1.3m plants 600 strains for every mu, male parent is 1 with the ratio of female parent: (10-15), neighbor distance is isosceles triangle and arranges in 5m between male parent and the male parent, male parent and maternal the 1st behavior female parent that is arranged as, the 1st, 2 strain kind female parents of the 2nd row, the 3rd strain kind male parent, 4-8 strain kind female parent, the 9th strain kind male parent, later on every the maternal 1 strain male parent of planting of 5 strains, by that analogy;

(3) field planting method: the 1-3d base fertilizer that stack retting is good evenly is sprinkled in the plantation ditch before the field planting, evenly be sprinkled into the plantation ditch by every mu of 50kg Russia nitrogenous (N: P: K=16: 16: 16) composite fertilizer again, with soil and base fertilizer, composite fertilizer is mixed, mulching soil then, the aligning method of pressing male parent and female parent is with the seedling field planting, the compacting root, set upright mobile jib, water sufficient normal root water, in order to keep moisture content, cover straw or thin soil again, decide bar at the above 7-10cm of grafting part place after the field planting, when the back branch length of germinateing arrives 10-12cm, stay 2-3 branch to make the 1st layer of branch, pinch when branch is grown to 20-30cm later on, the back branch that germinates stays 2 branches to do the 2nd when growing to 10cm, 3,4 layers of branch;

(4) fertilising: on the basis of following vola fertilizer, also need topdressing of growing period, growing period will keep soil moisture, around holding successfully with the drain ditch of centre, row with go between the drain ditch, in case rainy day ponding;

(5) extermination of disease and insect pest: note observing growing state every day, suction in general insect pest is used, stomach toxicity, killing insects by touching agent such as Rogor, cypermethrin, phoxim etc., when at every turn germinateing and the back of germinateing is every 1 insecticide of 15-20d spray, and pre-insect-pest takes place;

(6) receive mulberry seed: in time gather during sorosis blackening purple, sorosis is empocketed, firmly extruding then, mulberry seed is separated with pulp, pericarp, sorosis through extruding is placed in the sieve, immerses rinsing repeatedly in the water, obtain clean pure mulberry seed, after dehydration, dry and put into cloth bag, under 0-1 ℃ cryogenic conditions, deposit.

Advantage of the present invention is: this method is simple to operation, select loose, fertile sun-drenched sandy soil earth by adopting, grow seedlings wholely,, measures such as field planting parent, fertilising, the extermination of disease and insect pest, obtain clean pure mulberry seed, cultivation is promoted through peasant household, and mulberries output is improved, when improving the household economy income, also satisfied the demand in market.
