Technical field
The present invention relates to do not carry out preseeding irrigation cotton field under a kind of under-film drip irrigation precision drilling planting environment to keep a full stand of seedings method.
Background technology
In agricultural production, it is widely believed that the mulching planting technique of one of agricultural technology revolution has turned out to be peasant's increasing
One of important measures are produced, in the multinational example for having successful application in the worlds such as China, Japan, South Korea, the U.S., France, Canada,
The technology Yield in Cold, shortage of heat and need wrong season plantation area not only act as Meteorological effect, increasing both production and income effect
Fruit, can also effectively control weeds, inhibit the earth's surface accumulation of salt in the surface soil, prevent the fertilizer being manured into soil because wind, solarization, drench with rain due to lose, together
When promote soil microbial activity, accelerate the decomposition of organic substance, improve soil physical chemistry structure, created more for crop growth
Suitable ecological environment.All kinds of crops in China up to now(Containing vegetables)The long-term area of mulching planting technique is up to 5000
More ten thousand mu or more, wherein chief crop is cotton.
Drip irrigation technique is widely used, in China as a kind of advanced water-saving irrigation technique in developed country's agricultural production
The nervous area of water resource, particularly arid oasis farming region promote and apply larger, and up to 30,000,000 mu or so, production practices are demonstrate,proved
Its bright volume increase, water-saving benefit are very notable.
Sowing seeds technology is the light simplification technology of a mature and reliable, promotes the technology and not only eliminates final singling link,
Seed is saved, strong sprout is not influenced and early sends out, and be remarkably improved and plant cotton benefit, the technology is considered as that most effective cotton is light at present
One of simple cultivation technique.
Cotton cultivation with film mulched drip irrigation sowing seeds technology is that mulching planting technique, drip irrigation technique and sowing seeds technology are organic
With reference to and formed modern cotton Cultivate administration new technology, at present China promote and apply area at 18,000,000 mu or so, usually
In the case of, method of keeping a full stand of seedings is one of key link under under-film drip irrigation precision drilling planting environment, to meet cotton " emergence water "
Demand, in addition to suitable moisture in the soil site preparation, selection improved seeds, science investment fertilizer, it is necessary to 1-2 irrigation is carried out before sowing cotton seed,
General water consumption is in 200 m3/ mu or so after cotton irrigation before seeding, treats soil moisture content between 13.0-16.7%, and most
Good sowing season has arrived, and starts fertilising, site preparation, sowing, although this seeding technique is more ripe, due to by growing area nature
Ecological condition limitation, weather disaster take place frequently and the influence of the other factors such as unordered water resources development, along with irrigation before seeding
Water consumption is larger, causes cotton field preseeding irrigation under under-film drip irrigation precision drilling planting environment that cannot ensure throughout the year.
By taking Xinjiang, China cotton region as an example, under the smaller background of past planting scale, cotton method of keeping a full stand of seedings is included in cotton
Irrigation before seeding is completed by a big yield quota winter irrigation or spring irrigation before flower sowing, some cotton fields even winter irrigation and spring irrigation respectively carry out
Once, single winter irrigation and spring irrigation water requirement are generally 150-230 m3/ mu, but since Xinjiang winter irrigation or spring irrigation water source mainly come
From high water snow water, winter irrigation or spring irrigation corresponding period substantially respectively the prior year by the end of October to by the end of December with mid-February current year to 3
The middle ten days and the last ten days moon, time period weather temperature is relatively low, and high water snow water melts difficult, it is difficult to form sufficient water source, and with agriculture raw
Production scale and industry and the quick increase of urbanite water consumption, further resulting in irrigation before seeding water can not ensure.It is endless according to inventor
Complete to count, at least 13,000,000 mu of under-film drip irrigation precision drilling cotton fields cannot carry out preseeding irrigation in reality, particularly possess ten million
The Northern Xinjiang cotton region almost all in mu cotton field cannot carry out preseeding irrigation.
Research shows that:Preseeding irrigation cotton field is not carried out under cotton cultivation with film mulched drip irrigation precision drilling planting environment such as by normal sowing
Method disposably completes kind of a bed shaping, trench digging, is laid with drip irrigation zone, plastic film mulch, press mold, punching, precise-amount seed dibbing, sowing when sowing
The operation procedures such as row earthing and suppression, soil pressing on membrane, due to current precision drilling, the amount of sowing is small, and the single cave amount of sowing majority is only 1
Grain seed pushes up native strength more non-precision drilling cotton field much weaker when cotton emerges, cotton seedling top soil difficulty increases, and when emergence such as meets
Cotton seedling soil moisture content is not good enough, the more low poor environment of temperature, and cotton field will appear Some seeds surely cannot normally germinate the native phenomenon in top, separately
Outside, as Xinjiang cotton spring rain calamity in recent years endangers the increase of frequency, seedling stage rain calamity has become the major casualty of Xinjiang cotton
One of, when sowing cotton seed uses above-mentioned conventional method, the cotton seeding stage encounters the rainy day or after planting emerges water droplet irrigation method not
When strip " soil cursting " or " steel helmet " will be formed in the soil that covers of plantation row, and such as not broken " soil cursting ", cotton can not normally push up soil and go out
Seedling manually abolishes " soil cursting " even if emergence, also shows as that emergence rate is low, seedling is weak, and growing way is extremely irregular.
Researcher further investigates discovery:Kind cave center 0-10 cm temperature and soil moisture content are significantly compared with its kind of cave
It is low with the mulching film edge soil moisture of mulch junction, soil moisture content is poor, due to become light warm nature, the hydrotaxis of plant itself, cause cotton
The phenomenon that cotton seedling occurs to deviate kind cave center to some extent when flower pushes up soil emergence, cotton seedling top soil position is just in film when serious
Under, such situation such as nobody put seedling in time and cause high temperature burn seedlings under film and dead;Consider that cotton field puts seedling, abolishes " soil cursting ", even
It fills the gaps with seedlings, substantially increases cotton management recruitment, planting cost is caused to increase, along with big with yield caused by the above problem
Width reduce, finally cause plant cotton benefit significantly decline, therefore, as early as possible research and develop under-film drip irrigation precision drilling planting environment under not into
Row preseeding irrigation cotton field is kept a full stand of seedings method, very necessary.
