Description
(1) technical field
The present invention relates to saline land wheat cultivation technology, belong to agricultural technology field.
(2) background technology
The saline land area is about 400,000,000 hectares in the world.And just there is more than 2,340 ten thousand hectares in saline land in China.China's saline land major part is in uncultivated state at present, and the saline and alkaline arable land of small part output is also very low.Making full use of the salt tolerant crop salt resistant gene, to cultivate the anti-salt new variety of wheat of high yield (being) make new advances be that improvement utilizes the most basic, the most economical and effective method in saline land, also is a problem with great social effect and economic implications.In the world, the wheat salt tolerance breeding mainly is distant hybridization and the salt tolerant breed breeding that the PBI of international wheat and corn research center (CIMMY. Mexico) and Britain unites wild species such as carrying out wheat and goatweed, they have selected and can finish the hybrid wheat of the history of life in 200mM NaCl nutrient solutions, but because yield poorly, poor quality can't apply in agricultural production.Domestic, mainly be that Dezhou institute of agricultural sciences, the Chinese Academy of Agricultural Sciences, academy of agricultural sciences, Shandong Province and Shandong University etc. carry out the wheat salt tolerance breeding work.Successively bring out: salt tolerant winter wheat such as Shandong wheat 10, wheel anti-6 and wheel anti-7 and 0065.These kinds have certain salt resistance ability, and have certain scale to promote in saline and alkaline area.But the variety and quality that has is poor, as takes turns anti-series, plants skin depth and is kermesinus, not welcome by the peasant, and commodity value is low.Dezhou institute of agricultural sciences in 1997 and Shandong Normal University's scientific research cooperative that adversity plant is signed agreement on the physiological basis of the anti-salt of long-term breeding salt tolerant kind and crop, are carried out the seed selection of high yield salt tolerant New Winter Wheat Variety and the research of corresponding cultivation techniques in the past.The mode that seminar utilizes tissue culture technique and conventional breeding to combine, the principle of and minor-polygene reorganization complementary according to proterties selects for use the R-045-1 of anti-salt one-level to make female parent, and moral is selected No. 1 to hybridize as male parent.Get F
1The seville orange flower powder carries out tissue culture and obtains pollen plant, pollen plant is carried out chromosome doubling, hardening, transplanting, obtain seed at last, seed is bred with salt resistance and is identified, authorization in calendar year 2001 by Shandong Province variety of crops validation board, naming is that moral resists 961.
Though saline land wheat cultivation technology was also carried out experiment, cover wheat straw and draw hoe etc. before soaking seed, turn green as chemicals, adopt sweet native wheat conventional cultivation technology basically.Saline land wheat per mu yield at present is always about 100 kilograms.
(3) summary of the invention
The present invention is directed to the deficiencies in the prior art, a kind of saline land improving yield of wheat culture technique is provided.
Saline land of the present invention improving yield of wheat culture technique comprises that wheat seed selects the salt tolerant winter wheat variety for use, fresh water pressure salt is made moisture in the soil before broadcasting, with fertilizer is major-minor with saline land crop composite fertilizer, mulch bunch planting and spring chemical control, timely results, making salt content is that the saline land per mu yield of 0.3%-0.6% (percentage by weight) reaches about 400 kilograms.
Specify as follows to saline land of the present invention improving yield of wheat culture technique below:
1, selects the salt tolerant winter wheat variety for use
Selecting strong, the colory wheat breed of salt resistance for use is the germplasm basis that guarantees saline land winter wheat high yield.The first-selected moral of the present invention is anti-961, and the Shandong kind is examined word the [2001] No. 036, Ministry of Agriculture's cereal and quality of item supervision and inspection center 2001-520 number, but be not limited thereto, the close or Bhide of salt tolerant and moral anti-961 resist 961 more the high-quality wheat variety of salt tolerant also can select for use.
2, fertilising
Mix composite fertilizer when using sufficient base manure.Execute on the high-quality farmyard manure 2000-3000 kilogram basis at mu, together ploughing under in the soil behind 45～55 kilograms of composite fertilizers (N, P, each 15% percentage by weight of the K) mixing, be the soil moisture conservation feelings, rake drag soil moisture conservation is immediately begun sowing in good time after ploughing.
When applying above-mentioned base manure and composite fertilizer, can also apply Wheat Production compound trace element fertilizer commonly used, with microelement-supplementing Mn, Fe, Cu etc.
When can or pressing salt to make moisture in the soil before pressing salt to make moisture in the soil, fertilising carries out.
The alkaline land soil main feature is that the content of organic matter is low, the poor phosphorus of nitrogen stress, and the mineral nutrient is unbalanced, micro-wretched insufficiency.According to factor such as being difficult to topdress behind above characteristics and the overlay film, disposablely using sufficient base manure and sneak into composite fertilizer and little fertilizer just becomes the another important step of saline land winter wheat high-yield cultivation technique.
3, broadcast preceding fresh water pressure salt and make moisture in the soil
Adopt flooding irrigation method to water hydraulic pressure salt on October prior to seeding 10～20 and make moisture in the soil, plough deeply whole ground after 3～5 days, finish and plough deeply mulch bunch planting in the whole ground 1～3 day.
Beach saline land waters hydraulic pressure salt and makes moisture in the soil and plough deeply whole and the sowing time need shift to an earlier date 3～5 days.
Do not have enough rainfalls before broadcasting, the topsoil salt content is higher than under 0.25% the condition, fresh water pressure salt before broadcasting, and making the moisture in the soil sowing just becomes the key link that saline land winter wheat seedling is complete, seedling is neat.Especially under the mulch bunch planting situation, fresh water pressure salt not only plays the pressure salt action before broadcasting, and to increasing soil moisture, the higher soil moisture of wheat whole growing and all playing an important role than low saline salinity.
4, mulch bunch planting
Sow with Mulching and hill-drop sowing machine.8～18 seeds in every cave.
Because Mulching and hill-drop sowing machine may cause displacement at seeding time, therefore, the back of emerging is pulled out seedling from respective aperture, use the soil pressure film simultaneously, in case winter, strong wind lifted away film.
Because overlay film ground temperature is than not the high 1.5-2.0 of overlay film ℃.Prosperous length before the winter can suitably be postponed about a week than general wheat and being sowed.
5, spring chemical control
After turning green spring, grow the 1st young leaves and the 2nd young leaves when just having occurred foliage-spray wheat industry rich, i.e. 20% chlormequat chloride paclobutrazol microemulsion.Every mu of one bottle of 50ml converts 30 kilograms in water.
The wheat shooting stage ground temperature of standing up gos up soon behind the overlay film, and soil salt content is relatively low, and water content is higher, easily causes the growth of plant base portion 1-2 joint too fast, and supporting tissue is undeveloped relatively, causes the later stage to meet the wind and rain lodging underproduction.At this time foliage-spray wheat industry is rich, and lodging-prevention behind the overlay film and volume increase are had remarkable result.
In time results, should in time be gathered in the crops because natural calamities such as hail, strong wind and wet weather cause the underproduction for fear of wheat harvest.
Excellent results of the present invention is as follows:
1, the whole growth puberty does not water, and has significant ecology and economic benefit and adopts mulch bunch planting to suppress the salt affected soil accumulation of salt in the surface soil effectively, improves ground temperature simultaneously, keeps soil moisture content, and the wheat whole growing need not be watered, and has saved a large amount of freshwater resources.Only save and turn green and ear that water for twice just can every mu of saving water rate 40-50 unit.On the other hand, the area, saline land is the deficientest area of freshwater resources often, and wheat fertility in spring needs the water minimum phase of peak period rainfall.In the case, technology of the present invention has reduced the consumption of freshwater resources, because wheat seedling and mulch film greatly reduce surface evaporation, is of great significance to improving the saline land area ecological environment.
2, save the labour, increase economic efficiency adopt mulch bunch planting after, make the wheat whole growing need not cut weeds, water, topdress and field management link such as hoe, saved a large amount of heavy manual labors.10 workdays can be saved in the about every mu of ground of wheat whole growing.Each workday can be saved 150 yuan by 15 yuan.
3, reduce production costs, every mu about 60 yuan of the used mulch films of remarkable in economical benefits present technique, and save about 200 yuan of water rate and labour, also surplus about 140 yuan.About 3000 yuan of Mulching and hill-drop sowing machine (four-wheel or hand tractor carry) is sowed 30-40 mu every day, can buy one in tens families, uses for many years.Used 10 years by every, every mu of sowing takes 5-10 unit.But, because this choice of technology salt tolerant new variety of wheat moral resists 961, has guaranteed that by above saline land improving yield of wheat culture technique the seedling full stand is neat, reduce dead seedling of accumulation of salt in the surface soil phase in spring, help individuality and population growth and grow, making salt content is that per mu yield reaches about 400 kilograms on the 0.3-0.6% saline land.And the wheat per mu yield of conventional cultivation has only about 100 kilograms or total crop failure.Every mu is increased production 300 kilograms at least.By 1 yuan of per kilogram wheat, every mu can increase by 300 yuan at least, adds 130 yuan that water with labour's saving, and every mu can increase by 430 yuan altogether.As seen its economic benefit is very significant.
4, have wide promotion prospect China that more than 3.5 hundred million mu of saline land is arranged, wherein 25% for ploughing.Except that coastal region, mainly be distributed in landlocked arid and semi-arid lands.Saline-alkali wasteland mainly is distributed in strand and the Northwest, and saline and alkaline arable land then mainly is distributed in the Yellow River and Huai He River sea and Northeast plain area, and these areas are China wheat main producing regions.Only just there are more than 2,100 ten thousand mu of saline lands the Shandong Province.Along with sharply reduce in fast development arable lands such as urbanization and industrialization.On the other hand, because using chemical fertilizer etc., bad irrigation and excess produce a large amount of new saline lands again.Therefore, development and use China several hundred million mu of saline lands just become me with very urgent and difficult task in the agricultural production.This cover saline land winter wheat high-yield cultivation technique has water saving, labor savings, low cost and high production and simple and easy to do characteristics, and more than one hundred million mu of saline lands of development and use China are had very broad application prospects.
