Description
Technical field
The invention belongs to the technical field of agriculture breeding, be specifically related to the seed selection and the cultivation method of a kind of colory paddy rice " precious farming 34 ".
Background technology
The seed selection of agricultural breeding is to improve crop yield, improves the Basic Ways of crop quality.The seed selection and the natural conditions such as cultivation and geography and climate of agricultural breeding are closely related.Carry out the variety of crops improvement with suiting measures to local conditions, become the important topic of developing agricultural, each country, each area is all dropped into suitable human and material resources and is carried out related science research.
Paddy rice is the topmost cereal crops of China.Vast territory and abundant resources in China, vast in territory, the natural conditions of various places differ greatly.In Shanghai, East China such as Jiangsu, Zhejiang, Anhui, weather is moderate, is the major production areas of China paddy rice.Its rice varieties is various.Especially in Soviet Union, Zhejiang, area, Shanghai, the rice varieties of main plantation respectively has characteristics at present, and its deficiency is also arranged.The rice varieties production ratio that has is higher, but the quality of rice is not ideal enough, and the rice quality that has is good, and mouthfeel perfume (or spice) is glutinous when eating, but output is not high, and the ability then resistant to lodging, disease and insect resistance that has is relatively poor, influences output, and so on.Along with the raising of people's living standard, people are to the quality requirements of grain, comprise the quality requirements of rice more and more highlyer, and the new varieties that people expect to have the high-quality that is fit to local natural conditions, high yield, stable yields occur.
Summary of the invention
The objective of the invention is to cultivate a kind of suitable local natural conditions, produce high new rice variety of fine quality, and the cultivation method of this rice varieties is proposed.
The new rice variety selection that the present invention proposes, be the parental combination that adopts the fragrant glutinous rice of short bar high quality japonica " Han Feng " and characteristic " mouthful perfume is red ", through too much generation screening, the new varieties that acquired character is stable, through the Shanghai City crop varietal approval committee, naming is " precious agricultural 34 ".The concrete steps of seed selection are as follows:
1, select the pollen development time: the sword-like leave pulvinus is apart from 5-10cm, and thin fringe grain husk shell is light green, and it is yellow that the flower pesticide outward appearance is not changeed, and the pollen microspore is in the monokaryon, late period;
2, low temperature treatment: spike of rice put 5 ℃ refrigerator 60-84 hour;
3, disinfect: before the inoculation spike of rice is carried out disinfection.When adopting fringe, fine as weather, available 75% alcohol disinfecting.If overcast and rainy, need supernatant soaking disinfection with saturated liquor natrii hypochloritis;
4, healing rate is trained in raising altogether: microscopy is in the flower pesticide of growing optimum period and is inoculated into N
sOr M
sMedium adds 2,4-D 2PPM, KT 2PPM go out more medium, the flower pesticide middle part has little water droplet to form after 20-25 days, produces callus again after 5-10 days;
5, improve seedling greening-rate:, when callus reaches 1-2mm, in time change M over to through 5-10 days
sMedium adds KT 2PPM, the differential medium of IBA 0.5PPM, and green bud point produces after 7-10 days, and the callus base pitch constantly increases, and extracts green seedling again after 7-10 days out.Wherein, the green seedling of the part 3-4cm that sprouts earlier, long again root, the green seedling of this class have vascular bundle to form the survival rate height.When growing to the 8-10 leaf, 5-10cm can move to the nutritive cube hardening outward during height.
6, two sections are moved outward: (1) nutritive cube matrix is peat: rice chaff ash=2.5: 1-3.5: 1; (2) shelter from heat or light; (3) preserve moisture.Treat promptly to change grown in field over to after green seedling is taken root, survives, turned green.Wherein a part doubles as the zygoid plant naturally.
Through said method to parental combination after, screened through 92 years to 98 years more than 17 generations, of fine quality, anti-ly fall, the fine individual plant of high yield, progressively enlarged through 99 years to 2003 again and plant experimentally, stable yield is at 550kg/ mu--and 600kg/ mu shows the characteristics of high-quality, stable yields, moderate, the suitable multiple cultivation of ripe phase.The feature of this kind is as follows:
1, breeding time: about the 155 days time of infertility (about 152-160 days), ripe late round-grained rice type in the genus, comparison was according to elegant water 110 precocious 2-3 days.Conventional cultivation late May sowing, neat fringe at the beginning of 9 months, after ripening before October 25; Light cultivation by the end of May, at the beginning of 6 months the sowing, early September neat fringe, late October maturation.
2, quality: entrust national Ministry of Agriculture rice and quality of item supervision and inspection center check by Shanghai City seed management master station in March, 2002, and its every index reaches superior rice standard promulgated by the ministries or commissions of the Central Government as a result.Wherein, eight indexs such as brown rice rate 85.2%, polished rice rate 76.5%, head rice rate 72.9%, amylose content 16.3%, protein content reach the superior rice primary standard; Chalkiness degree, transparency, three indexs of glue denseness reach the superior rice secondary standard; Index of the white rate of chalk reaches the superior rice grade III Standard.Grain of rice good appearance, rising property of boiling is poor, rice is soft and glossy, hard after cold, palatability is splendid.
3, resistance: lodging resistance is strong.Through multiple planting type, the lodging phenomenon do not occur in medium-to-high grade fertilising over nearly 3 years, especially all kinds of fields piece does not have the large tracts of land lodging under the Direct-seeding Rice high density.Disease and insect resistance is general, and banded sclerotial blight is light.
4, agronomy: plant height 95-100 centimetre.Plant type is collecting and distributing moderate, and the leaf look dark green, and blade is slightly long, and sword-like leave is endured, and it is delicate and pretty to grow, and tillering ability is on the weak side.It is stable to plant property, and heading is neat.Mu is fringe 20-25 ten thousand effectively, and every total grain panicle is counted the 120-135 grain, real grain number 110-120 grain, thousand kernel weight 27 grams.The grain yellow, slightly oval, bran point lavender, threshing is medium.Blue or green stalk of later stage is lived ripe, the suitable for mechanization harvesting.
The cultivation method of " precious farming 34 " that the present invention proposes is as follows:
1, early sowing in good time.Do conventional cultivation sowing in-25 days on the 15th May in this area, the seedling transfer can be-30 days on the 25th May, and Direct-seeding Rice should be in 1-June 5 June.Sowing date for early sowing can satisfy vegetative growth phase, stem number of blade abundance, and fringe shape is big, favourable high yield.
2, rational close planting.According to this kind tillering ability a little less than, the characteristic that the percentage of earbearing tiller is higher is made the basic seedling of general planting and is controlled at about 8-10 ten thousand/mu, peak seedling is controlled at 30-35 ten thousand/mu, number of productive ear 20-23 ten thousand/mu.The basic seedling of light cultivation can be brought up to 10-12 ten thousand/mu, and peak seedling can be brought up to 36-38 ten thousand/mu, and the mu spike number can be loosened to 25-28 ten thousand/mu.Planting Patterns is capable better with width, and the photosynthetic nutrient accumulation of favourable increase helps increasing grain husk and spends number, enriches seed, improves thousand kernel weight, reaches the strong big fringe of stalk, the ripe high yield of living.
3, rationally rich water is planned strategies for.Honda the time of infertility approximately need pure N15-20kg.Fertilizing method: " preceding heavy, in steady, back mend ".Cooperate and enrich phosphorus, potash fertilizer.See that growth of cereal crop seedlings growing way and Ye Se change, surely execute ear manuer, promote the strong big fringe of stalk; Later stage fertilizer is too much unsuitable.Want sufficient water to do tripe on the water starch management, need water sensitive after the heading, keep dried wet, the later stage should prevent cutting off the water supply too early, guarantees three leaf vigor, raising ripening rate and thousand kernel weight.
