Abstract
The invention belongs to Rice Cropping technical fields, and in particular to management method by 3-9 pounds/acre of application instant nitrogenousfertilizer, and sprinkles profoundly water 2-3 days before transplanting before a kind of paddy drought seedling is transplanted, and no longer carries out other operations until transplanting is preceding.The present invention has the advantage that method was managed by 2-3 days before transplanting in the present invention compared with prior art, province prevents or cure a disease, worm prevents and treats process, instant nitrogenousfertilizer can act on rapidly the root of dry rice seedling, its root is acted on, make it be easy to extract in transplanting, improves transplanting quality and transplanting efficiency, high survival rate after transplanting, plant is managed according to a conventional method, and survival rate is higher.
Description
Technical field
The invention belongs to Rice Cropping technical fields, and in particular to a kind of preceding management method of paddy drought seedling transplanting.
Background technique
Rice is one of main cereal crops, guarantees that high yield has important meaning for grain, understands rice and moves
Time, method and Attention Points are planted, most important for rice yield, dry rice seedling only keeps soil during entire seedling
It is wet, the method for raising seedling of water layer, the modes such as common fertile bed fine earth method modeling plate seedling raising, open and close type film dry rice seedling, training are not kept
Strong seedling, cold-resistant, drought resisting, water-saving important method of raising seedling are educated, does not go here and there root, is conducive to the collocation of high-yield variety and the expansion of application range
Greatly, it convenient for unified for kind, but finds in actual operation, rice shoot is mostly before one heart stage of three leaves when rice seedling small transplantation of seedlings
Afterwards, tree transplanted is usually in four to five leaves more than the phase, and before the stage of transplanting seedlings, root system is not only long but also more, and lift seedlings needs one when transplanting seedlings
Fixed dynamics, when strength extracts rice seedlings, root system is impaired serious, and after transplanting, root regeneration takes a long time, may
Transplanting survival rate is influenced, but there are currently no reduce the impaired correlative study of root system.
Summary of the invention
The purpose of the present invention is being directed to existing problem, a kind of preceding management method of paddy drought seedling transplanting is provided.
Rice seedling applies instant nitrogenousfertilizer, i.e. urea before transplanting, and main function is to make the quick strong sprout of rice shoot, while energy
The cell tissue that root system end absorbs nutrient, that is, radicula part or fibrous root are injured within the extreme time, it is made to become crisp
Weak, i.e., so-called burning root transmits the thick root portion in rear portion of nutrient also although radicula part receives injury to a certain extent
Do not injured, still maintain original toughness and elasticity, pull up seedlings in this case seedling when, transmitting nutrient is played in rice shoot root
The radicula part of thick root portion and front absorbent nutrient disconnects one by one, therefore is easy to improve and pulls up seedlings speed without influencing rice shoot suction
The root adopt point, the rice shoot additional issue new root of being completely cured for being transplanted to crop field is very fast, improves survival rate similarly with cutting a root and inspiring new root；
The tree of many years is survived in nitrogen application excess, will be dead because root is burnt, because root system absorbs the thin of moisture and nutrition
Born of the same parents organize the injury by quick-acting fertilizer, and application Nitrogen, phosphorus, potassium three elements balance apply the normal life that can guarantee plant
It is long, effectively reduce the generation of pest and disease damage.
The present invention is achieved by the following technical solutions: a kind of preceding management method of paddy drought seedling transplanting, before transplanting
It 2-3 days, by 3-9 pounds/acre of application instant nitrogenousfertilizer, and sprinkles profoundly water, no longer carries out other operations before transplanting.
As further improvement of these options, the dry rice seedling is on the seedling bed earth for the flat surface for being easy to irrigate
Furrow stalk is carried out in nursery before nursery, is applied the compound fertilizer that nitrogen content is 12% by 20-30kg/ mus and is made base fertilizer；The dry rice seedling
Seedling bed earth pH value be 7.2-7.6；Dry rice seedling covering and heat insulating moisture film on seedling bed in cultivating process is kept
There is water in moisture film for a long time, not top dressing makees base fertilizer using the compound fertilizer that nitrogen content is 12%, can be effectively reduced pest and disease damage
Illness rate, streamlining management process increase strong sprout rate.
As further improvement of these options, the quick-acting fertilizer is urea, ammonium chloride, ammonium nitrate or ammonium sulfate.
As further improvement of these options, the usage amount of the instant nitrogenousfertilizer is 4-5 pounds/acre.
As further improvement of these options, the rice shoot height that 2-3 days judgment criterias are 90% before the transplanting reaches
To 13cm or more, the flat width of rice shoot vacation stem reaches 4mm or more.
The present invention has the advantage that method was managed by 2-3 days before transplanting in the present invention compared with prior art,
Province prevents or cure a disease, worm prevention and treatment process, and instant nitrogenousfertilizer can act on rapidly the root of dry rice seedling, act on its root, make its
It is easy to extract when transplanting, improves transplanting quality and transplanting efficiency, high survival rate after transplanting, plant are managed according to a conventional method,
Survival rate is higher.
Specific embodiment
Detailed description of the preferred embodiments below.It should be understood that described herein specific
Embodiment is merely to illustrate and explain the present invention, and is not intended to restrict the invention.
The present invention will be described in detail by way of examples below.
A kind of preceding management method of paddy drought seedling transplanting, when 90% rice shoot height reaches 13cm or more, rice shoot vacation stem is flat
It after width reaches 4mm or more, by 4 pounds/acre of application instant nitrogenousfertilizers, and sprinkles profoundly water, no longer carries out other operations before transplanting, 3
It is transplanted after it.
Wherein, furrow stalk is carried out in dry rice seedling nursery on the seedling bed earth for the flat surface for being easy to irrigate before nursery,
The compound fertilizer that nitrogen content is 12%, which is applied, by 25kg/ mus makees base fertilizer；The pH value of the seedling bed earth of the dry rice seedling is 7.4；It is described
Dry rice seedling covering and heat insulating moisture film on seedling bed in cultivating process keeps having water for a long time in moisture film, and not top dressing utilizes nitrogen
The compound fertilizer that cellulose content is 12% makees base fertilizer, can be effectively reduced the illness rate of pest and disease damage, and streamlining management process increases strong sprout rate.
Quick-acting fertilizer selects urea in the present embodiment, and rice selects new rice variety paddy excellent 596.
It is 1275.8mm in local 2016 precipitation；Rice seedling is easier to extract than existing method when transplanting, right
Root damage is smaller, and the thick root portion of transmitting nutrient is played in rice shoot root, and when transplanting is 7500 nests per acre, and yield reaches 592kg/
Mu.
Wherein existing method is the watering of stoppings in 3 days before transplanting, and when lifting needs soil at rice shoot using auxiliary tool
It loosens.
It is 1163.5mm in local 2017 precipitation；Rice seedling is easier to extract than existing method when transplanting, right
Root damage is smaller, and the thick root portion of transmitting nutrient is played in rice shoot root, and when transplanting is 7500 nests per acre, and yield reaches 617kg/
Mu.
