Abstract

The present invention relates to a method of directly-sowing pressing seed into mud for making rice obtain high yield and its tool. Its technical key points include: selecting seed, chemically-removing weeds, do not feed water into rice field, deep-applying basic fertilizer and directly-sowing pressing seed into mud. Its tool includes drum type seed-pressing device with wire fabric with 10 meshes and multi-teeth mud weed-removing rake, etc.

Description

Rice direct-seeding pressing-seed-into-mud method for high yield and instrument

Technical field the present invention relates to paddy rice and cultivates technology, and especially paddy rice is pressed mud sowing high-yield method.

In the background technology prior art, the technology of cultivating of paddy rice is moved sanction based on seedling, though early program request is arranged, broadcast sowing test, can not successfully promote and come, and reason is that it can not solve weeding, resistant to lodging and high yield problem.

Summary of the invention the object of the present invention is to provide a kind ofly can save paddy rice cost (kind, worker, water, fertilizer etc.), can improve the paddy rice of rice yield again to cultivate method, i.e. rice direct-seeding pressing-seed-into-mud method for high yield and instrument.

The technical solution adopted for the present invention to solve the technical problems is: matched kind, the field is accumulated water not, deep placement base manure, and weeding is pressed and is planted, and is equipped with roller and presses kind of device and mud weeding to weed rake.Technical process: with the southern areas, Hunan is example (or plant the double cropping rice area, when ground temperature more than 15 ℃), two season kind vegetative period can not be above 215 days.Early rice: accomplish fluently weed killer herbicide after about five day the rice field 10-15 days (as March 2) before the predetermined sowing, by opening the whole good field of railway carriage or compartment requirement plow harrow, before ploughing a field, use sufficient base manure earlier, potassium chloride particularly, buried base manure, put in order good field 5-7 days prior to seeding (about March 30), require 9-12 rice one railway carriage or compartment, dug the drain ditch, the railway carriage or compartment piece will be made into turtleback shape, can not accumulated water in the railway carriage or compartment, as figure, April 5, mud was pressed in the front and back sowing, divided by the railway carriage or compartment and planted, sowing quantity: 0.9 kilogram (conventional variety)/mu (3.4 ten thousand root and stem of certain plants/mu) → 0.6 kilogram (hybrid rice)/mu (2.3 ten thousand root and stem of certain plants) → 0.3 kilogram (super hybrid rice)/mu (1.1 ten thousand root and stem of certain plants), broadcast sowing or program request or drilling, to make it density roughly even as far as possible, presses kind of a device rolling pressing-seed-into-mud with cylinder, moistening field can roll out mud and cover brokenly the chest seed-grain that shows money or valuables one carries unintentionally, thick mud field presses paddy to go into about 1 centimeter of the mud degree of depth, and semilate rice type of seeding process is the same with early rice, and the temperature when it is not sowed influences, late rice presses mud to sow the branch railway carriage or compartment, whole ground of not ploughing a field, and lives the root and stem of certain plants phase.The special tool that the present invention adopts have multiple tooth rake (mud weeding) and on establish 10 order steel wires drum-type press a kind device (pressing-seed-into-mud back and forth rolls).

Good effect of the present invention is: it moves the sanction technology relatively with the seedling of the identical level of production, and Zhi Xiaoguo is as follows for its volume increase joint: rate of growth 5-10% volume increase 50-100 jin/mu increases income coin 50-100 unit; Economize 50% because of exempting from seedling, moving worker such as sanction and save 3-4 working day/100 cubic metres/mu of mu late rice water savings; Exempt to save coin 50-90 unit/mu with rice seedling bed 100-120m2/ mu; Joint plants about 50%, saves 10 yuan/mu; Can deduct 7-10 days vegetative period, for the rice continuous cropping of two seasons provides condition.

Embodiment

Double rice cropping system, early rice: selected collocation is rice varieties sooner or later, be no more than 215 days two vegetative period in season, can exempt from seedling, connect live containing, and (with Hunan Nan Daoqu is example to early rice, temperature is stabilized in more than 12 ℃) can before and after April 5, sow, played weed killer herbicide, and used sufficient base manure, particularly potassium chloride in 10-20 days before this, buried base manure ploughs a field, by dividing the railway carriage or compartment, drainage requirement, leveling railway carriage or compartment piece, the wide 9-12 rice in its railway carriage or compartment, piece middle part, railway carriage or compartment is high, both sides are low, are convenient to railway carriage or compartment ditch and drain ditch draining, make the railway carriage or compartment piece become the not wet mass of accumulated water, by the broken chest of minute railway carriage or compartment piece area distributions seed-grain amount that shows money or valuables one carries unintentionally: 0.9 kilogram (conventional variety)/mu, 3.4 ten thousand root and stem of certain plants/mus; 0.6 kilogram (hybrid rice seed)/mu, 2.3 ten thousand root and stem of certain plants; 0.3 kilogram (super hybrid rice)/mu, 1.1 ten thousand root and stem of certain plants).Can be manually to railway carriage or compartment piece uniform broadcasting, the sowing of also available drill planter or dibbler is pressed kind of a device pressing-seed-into-mud with drum-type, and about 0.5 centimeter of the degree of depth is opened and is splited open the field and can press kind flatly with mud, and moistening field can roll out mud and cover seed-grain, and thick mud field presses Gu Zuishen to be no more than 1 centimeter.Semilate rice sowing can by early rice sowing requirement, be played weed killer herbicide in May (or local suitable sowing time), basal dressing, whole divides railway carriage or compartment, requirement to sow pressure mud.Late rice need not plough a field in the field that early rice has been gathered in, and directly sowing presses paddy to go into mud, and mud extraction in 3-5 days is come into leaves, and begins to tiller.

Claims

1. rice direct-seeding pressing-seed-into-mud method for high yield, technical essential is, match kind, chemical weed control, the field is accumulated water not, deep placement base manure, live pressing-seed-into-mud is characterized in that: a). variety matching, double rice cropping system sooner or later two season kind vegetative period can not be above 215 days, live early rice before and after the Ching Ming Festival, early rice harvesting back is the no-tillage and direct-seeding late rice then; B). chemical herbicide, before whole ground basal dressing, executed chemical herbicide and harrowed the mud weeding at the field of kind of an early rice, semilate rice piece in 10-15 days with multiple tooth weeding; C). deep placement base manure is to use sufficient base manure in the piece of rice field in morning of several days after playing chemical herbicide, particularly potassium chloride; D). the field is accumulated water not, is to require by wide minute railway carriage or compartment of 9-12 rice wholely, begin to rehearse ditch and high yield ditch, it is high that the railway carriage or compartment piece wants the middle part to omit, and both sides are low slightly, are turtleback shape, and the water of being convenient in the piece of railway carriage or compartment discharges toward drain ditch, branch railway carriage or compartment and high yield ditch, makes the railway carriage or compartment piece be wet mass; E). live pressing-seed-into-mud is directly to broadcast sowing in the piece of railway carriage or compartment or with the program request of program request apparatus, then with the drum-type pressure kind device pressing-seed-into-mud degree of depth 0.5-1.0 centimetre that rolls back and forth.
