Description

Paddy rice nonirrigated farmland direct-seeding planting method
Technical field
The invention belongs to agricultural technology field, particularly a kind of paddy rice nonirrigated farmland direct-seeding planting method.
Background technology
Paddy rice is the maximum cereal crops of China, is also the first rich and influential family with water, about has the agricultural water of 70% for Rice irrigation.Along with the growth of population, cities and towns and industrial expansion, the change of global climate and increasing the weight of of environmental pollution, the water resource for crop irrigation is more and more deficient, the development of serious threat crop particularly Rice Production.
Paddy rice nonirrigated farmland direct-seeding planting method develops from rice direct-seeding mode, is namely to select drought-enduring variety, live under the situation of nonirrigated farmland, seedling stage non-irrigated length, the middle and later periods utilizes rainwater and suitably irrigates to meet the kind rice method that rice strain needs water requirement.Some state farms, northern China rice fifties district are on the basis of direct sowing on dry paddy field, and for solving the problem of source of irrigation water deficiency, test " rice seedling drought length and middle and later periods pour water ", can be described as the blank of rice dry-farming.At the beginning of the seventies, northern area Continuous Drought, crop investigations institute of the Chinese Academy of Agricultural Sciences began one's study from 1973 and promotes rice dry-farming, and rice in north china dry farming once developed very fast in the eighties, and by 1985, the application area of 13 provinces and cities in the north reached 160,000 hectares.Rice dry-farming, not only saves irrigation water 25% ~ 40% than common paddy field rice, and can reduce the operation sequence (as seedling, transplanting etc.) in Rice Production, saves recruitment, is convenient to mechanization production.The difference of rice dry-farming compared with direct-sowing dry is: direct-sowing dry be drought whole, drought after planting, pour water immediately, thereafter water consumpation management the same with transplanting rice, maintenance water layer; Rice dry-farming is that dry land fertilizer spraying is emerged, and keeps one period non-irrigated long, does not pour water, and the middle and later periods according to circumstances takes shallow irrigation, shallow-wet intermission to irrigate or regular moistening irrigation.The difference of rice dry-farming compared with conventional transplanting rice: one be modify-water is the whole ground or no-tillage of drought wholely, saved a large amount of to plough, whole water; Two is change seedling to transplant as nonirrigated farmland is live, and simplify field operational sequence, production labor is reduced, labour intensity obviously reduces; Three are modify-water field kind rice is nonirrigated farmland kind rice, owing to not needing to keep water layer, can plant rice, thus widened kind rice scope on the nonirrigated farmland having irrigation conditions; Four is modify-water layer-managements is no water layer management, to meet the physiological water requirement of rice strain, the availability of water is significantly improved; Five is because rice dry-farming does not keep water layer, and only carry out moisture management, can not raise subterranean water level, seepage is less, does not have the threat of Secondary Saline, and soil physical and chemical property is also than good under the state of basining irrigation.Rice seedling grows under good gaseity, first take root, after emerge, branch root and Gen Maofada, rice strain is anti-fall, the ability of drought resisting and some sick worm anti-strengthens.Soil permeability is good, and growth intermediary and later stages soil redox potential is higher, and the rice root vigor retention time is long, is conducive to Grain Filling, and thousand kernel weight is higher.But also there is many problems in rice dry-farming in cultivation.Such as, drought compares wholely takes a lot of work, especially larger in whole ground, rich clay area difficulty; Cannot washing salinity by irrigation before sowing, dry farming should not be carried out in heavy saline; Rice dry-farming does not keep water layer, ground moistening, and weeds easily grow and weeds kind is many, and harm is heavy, and artificial weeding effect is poor.
Application number be 201010501579.1 China apply for a patent and disclose a kind of rice direct-seeding dry farming improving straw mulching high-yield cultivating method, specifically after rice direct-seeding with improving straw mulching; Carry out chemical weed control after planting, before improving straw mulching, control weeds and occur; Thereafter, man-made irrigation moisturizing is carried out according to soil moisture content.But there is following shortcoming in the method: one is that the breeding time of paddy rice postpones, and mostly postpones more than 10 days because drought in seedling stage is long-time long; Two is that emergence rate is low, and seedling rate of living is low, needs to strengthen seeding quantity; Three is that rice dry-farming does not keep water layer, ground moistening, and weeds easily grow and weeds kind is many, and harm is heavy, and artificial weeding effect is poor; Four is cause arid because needing different growing the index of artificial recharge indefinite and reduce output; Five is that artificial recharge increases labour intensity, and cost is higher.
Summary of the invention
