Abstract
A method for cultivating corn in order to fight against drought and preserving the fertilizer in soil includes such steps as preparing soil in the autumn for collecting the rain in the soil, sowing in the spring in the furrow mode for decreasing the loss of water and soil, topdressing, and changing the furrows to bed for preserving water and fertilizer.
Description
Technical field
The invention belongs to farming operation management, be specially adapted to that northeast is half moistening, the dry farming rainfed farming of semiarid region, be a kind of drought resisting, keep a full stand of seedings, protect the novel corn methods of cultivation fertile, that prevent wind erosion, weed eradication, high yield.
Technical background
Temperate zone, northeast half moistening, semi-arid climate type, annual precipitation 300-500mm, average out to 419.8mm, 60-70% concentrate on 6-8 month.Year evaporation discharge 1600mm is about 3.5 times of precipitation.Spring, arid was short of rain, much wind weather, and annual mean wind speed 4.8m/s, maximum mean wind speed appears at April, and minimum windspeed appears at August.The zonal soil type is chernozem and chestnut soil, and azonal soil is aeolian sandy soil and saline soil.
Many reclamation of wasteland grassland, this zone is the farmland, and the conventional tillage mode is whole ground in spring, ridge platform kind plant.Spring precipitation is few, and some areas are to hit by drought 9 years out of 10, and again on the occasion of the strong wind phase in spring, early spring, the evaporation of soil moisture certainly will be accelerated in whole ground, and the soil loss of moisture is serious, and is totally unfavorable to sowing in spring; Because the farmland topsoil is loose, has increased the weight of the soil erosion; Arable land topsoil, particularly plasma are swept by strong wind, make it to become the dirt source; Fertile topsoil is eroded, and soil fertility is descended greatly; At ridge platform upper seeding wheel, running into the strong wind weather seed can be scraped, and occurs being short of seedling, shoot-breaking phenomenon.Corn is that this distinguishes main raise crop, and flowering stage and milk ripe stage are critical period of water requirement, and water requirement is big, but local area precipitation in summer abundance can guarantee growth needs substantially.Though corn water requirement in seedling stage is little, this phase precipitation is the key period of moisture seldom.Therefore how to increase the soil moisture content in early spring, reduce moisture loss, increasing emergence rate is the key that solves the spring sowing problem.
Make full use of natural rainfall, improving water use efficiency is one of key issue of rainfed farming research.China to evaporating as increasing soil water storage, reducing by cultivation step, enriches fertilizer in the arid and semi-arid area at present, and agronomic measures such as water-saving irrigation improve the water use efficiency aspect and carried out a large amount of research.Concrete measure can be built terraced fields by leveling land, and utilizes kiln cellar for storing things afflux rainwater etc., fully saves limited precipitation; Utilize suppression soil, soverlay techniques such as mulch film, stalk reduce the invalid of soil moisture to greatest extent and scatter and disappear; By enriching fertilizer, spray various growth regulators, improve crop water utilization ratio and output.But these methods all need the peasant that corresponding economic the input arranged, and have increased production cost, have increased the pollution to the soil.
Summary of the invention
The object of the invention provides a kind of half moistening, semiarid dry farming rain-fed agriculture region northeastward and carries out whole ground in autumn, furrow sowing in spring, and after the typhon mouth phase topdressed, ridging became furrow the novel methods of cultivation of ridge platform.
Put in order the more autumn and winter sleet of farmland receivability on ground autumn, and soil moisture content is increased, and make upper soll layer that the process of consolidation gradually be arranged, thereby more weather-proof than the chesson behind the whole ground of spring.Show that according to the field experiment result autumn whole ground soil moisture content is significantly higher than whole ground of spring, spring and autumn, whole ground furrow soil moisture content all was higher than the ridge platform.Collect fine sand in the furrow on whole ground of autumn, make the furrow face of land, 5cm ground temperature be close to or higher than the temperature of ridge platform.This microenvironment of furrow provides hydrothermal condition preferably for emergence of corn, and the plantation protection effect is good in furrow, the emergence rate height.
In corn typhon mouth phase ditch, apply fertilizer, break former ridge platform then, make furrow become the ridge platform, make corn root and fertilizer all cover thicker soil horizon like this, the wheel number of corn nodose root is increased, underground stipes elongation, increase suction, fertile ability, improved water use efficiency; The fertilizer volatilization is slowed down, reduced the fertilizer waste, protect fertile effective.The corn late growing stage has improved ground temperature owing to furrow becomes the ridge platform, and prevents the effect of heavy rain waterlogging in summer stain.The corn that makes furrow plantation in early stage later stage ridge platform way to manage than simple ridge platform maize planting have that leaf is dark green, the greenery area longer duration, stem is thick, nodose root is many, the subterranean stem joint joint characteristics that spacing is long, output is high.
Patent of the present invention comprises following process:
Autumn whole ground: October 20 was implemented stubble-cleaning, ridging and suppression before freeze-up after the annual autumn harvest.
Furrow sowing in spring: sowing before and after the May 1 in every year.In the serious time of spring drought, sit water in the furrow, apply fertilizer, sow, earthing 5cm once finishes.As in the more time of spring precipitation, but apply fertilizer in the furrow, sow, earthing 5cm once finishes.
The intertillage management: the typhon mouth phase imposes chemical fertilizer between the furrow milpa, break original ridge platform then, gives the furrow earthing, makes original furrow become the ridge platform.
Field management: early stage, seedling management, whole growth phase weeds management, later stage stalk were identical with the conventional tillage mode with grain harvest.
If happen much wind weather in sowing time, and precipitation is few, can suitably postpone sowing date is on May-20 on the 10th.If a precipitation process reaches 10mm before and after May 1, sowing at once can be sat water.In the plot that does not have shelter forest, whole ground of autumn is stubble-cleaning not, toothing 10-15cm, and dark time furrow, control ridge height is 18-20cm.
The present invention mainly produces following beneficial effect:
(1) the more autumn and winter precipitation of autumn whole ground furrow receivability increases soil moisture content; It is less to break ground when sow for spring, has reduced water and soil loss.
When (2) the typhon mouth phase topdressed, ridging became the ridge platform with furrow, the thickness of earth-fill cover of thickening fertilizer and corn root, and the fertilizer efficiency fruit is protected in raising, has increased the number of plies of nodose root, improves the ability of plant suction, fertilizer, thereby has improved output.
(3) during middle term management, break the ridge platform and can play for the furrow earthing to turn over the purpose of pressing weeds.
(4) method is simple, easily promotes, and can obtain better economic, ecological benefits.
