Abstract

The invention belongs to the field of rice cultivation, and relates to an accurate triple-hole rice seedling cultivation technology. The accurate triple-hole rice seedling cultivation method comprises the following steps of: raising triple-hole group rice seedlings, and performing point slinging or swing planting. Triple-hole plastic plate dry raising control is adopted for cultivating strong seedlings, so that one third to two thirds of slinging planting holes are reduced, the seedling slinging or swing planting speed is improved, the labor force is remarkably saved, the labor cost is reduced, the rice seedlings are distributed uniformly, holes in a field are reduced, the holes have good ventilation and light transmission, the individual seedlings are robust, the group structure is optimized, high yield or ultrahigh yield of rice can be stably realized, the yield is increased by over 10 percent, and the effect is increased by over 15 percent.

Description

Paddy rice 3 connects the accurate cultivation of hole rice shoot

Technical field

The invention belongs to field of rice cultivation, relate to a kind of paddy rice 3 and connect the accurate culture technique of hole rice shoots, can reduce by every mu of planting hole number, reduce labor intensity and shorten the activity duration, be beneficial to increasing production of rice, high yield and super high-yielding.

Background technology

Present rice seedling throwing mainly adopts the plate seedling raising of moulding of single hole, every cave 3-5 rice shoot.1.8 ten thousand-2.5 ten thousand caves are planted in every mu of throwing, and it is too many that the cave number is planted in throwing, lavish labor on, and the rice shoot skewness, the space is little between the cave, and ventilation and penetrating light is poor, and damage by disease and insect is heavy, is prone to lodging, influences the high yield and the stable yields of rice seedling.

Summary of the invention

Many in order to solve existing rice seedling throwing cave (clump, down together) number, the labourer spends greatly, the rice shoot skewness, and colony's intermediary and later stages ventilation and penetrating light is poor, is prone to the problem of lodging, the invention provides a kind of paddy rice 3 and connects the accurate cultivation of hole rice shoot.

The technical scheme that the present invention adopted is, a kind of paddy rice 3 connects the accurate cultivation of hole rice shoots, and step is following:

Breed 3 earlier and connect hole group rice shoot, carry out a throwing or pendulum then and plant.

3 above-mentioned hole group of company rice shoots are to adopt three company's hole seedling dishes to breed; Said three company's hole seedling dishes are a plurality of seedling pits that on seedling dish plane, are provided with; Each seedling pit bottom is provided with aperture, and per 3 of described seedling pit is seedling cave of one group of formation, and 3 seedling pits in each seedling cave are equilateral triangle and arrange; And the seedling pit in the seedling cave makes 3 seedling pit locally connecteds formation three in each seedling cave connect cave (three connect the hole) in that the adjacent wall is recessed in twos.

Present technique is planted because of adopting the thin planting method, require rice shoot plant the back live fast, tiller early, seedling quality is had relatively high expectations, educate chemical control by strict drought, length of time rice seedlings grow 25-30 days, average every seedling band tiller was more than 0.5.

Employing 3 connects the hole and moulds the strong seedling of educating of dish drought control cultivation, and throwing is planted the cave number and reduced 1/3-2/3, improves rice transplanting or planting speed, significantly saves the labour; Reduce labour cost, and rice shoot is evenly distributed, cave, field number is few; Ventilation and penetrating light is good between the cave, and is individual healthy and strong, group structure optimization; Can stablely realize rice high yield or super high-yielding, raising the output is more than 10%, and synergy is more than 15%.

Fig. 2 is three company's hole seedling dishes photos in kind.

Fig. 3 is 3 company's hole rice shoots.

Embodiment

A kind of shown in Fig. 1 is used for paddy rice and throws seedling seedling dish that pendulum plants in order and ° rearranged by 145 rice shoot caves 1 Rotate 180 successively; Each rice shoot cave 1 is to be arranged with the equilateral triangle formula by three seedling pits 2 to constitute; Three seedling pits in each seedling cave 1 in twos adjacent cave wall to the lower recess hole dark 1/3 to 1/2, make these three seedling holes form locally-connected three and connect cave, the rice shoot that so brings out; The root system in three holes is ganged up into as a whole, is beneficial to throw to plant or planting.Three connect the cave the center do not have recessedly, therefore constitute a salient point or projection 4, it is dark that bump height is lower than the hole, seed divides uniformly in 3 seedling holes in the time of can guaranteeing to sow.Each bottom of educating hole 1 is provided with aperture 3, is used to regulate moisture.The hole is 1.6 centimetres deeply.

Use 3 connects hole seedling dish and cultivates of the right age strong seedling, and the severization control is also carried out drought and managed, and length of time rice seedlings grow 25-30 days, average every seedling band tiller >=0.5.

Because root system is ganged up into as a wholely in every cave, forms ball, like Fig. 3, point is thrown to spread to throw with tradition and is compared, and has both reduced throwing and has planted the cave number, has guaranteed the uniformity of rice shoot again.It is that every cave rice shoot is planted in soil according to certain distance between rows and hills pendulum that pendulum is planted, and generally just buries with the rice shoot ball and is advisable.Even hole rice shoot root band is native because of 3, and ball is not loose, and it is upright that pendulum is planted the back rice shoot, and this method planting speed improves 1/3-2/3 than the slotting root seedling of washing of traditional artificial hand.About 6 seedlings of the every cave of single cropping hybrid rice, the 6000-8000 cave is planted in the every mu of throwing in Japonica Hybrid land for growing field crops, every mu 6000 cave of hybridization long-grained nonglutinous rice; The general every cave of single cropping conventional japonica rice 6-8 seedling, every mu of throwing of large spike japonica rice variety is planted about 8000 caves, about every mu 10000 cave of middle fringe type kind, about every mu 12000 cave of spike number type kind; Every mu of 8000-10000 of two season indica hybrid rices ten thousand caves.

Accurately point is thrown by a line spacing is even and is thrown.Accurately pendulum is planted according to certain distance between rows and hills, by hand seedling alms bowl body is planted in soil, 30 centimetres of general line-spacings, and the spacing in the rows apparent density is regulated.

Claims

1. the accurate cultivation of paddy rice that connects the hole rice shoot is to breed 3 earlier to connect hole group rice shoot, carries out a throwing or pendulum then and plants.

2. method according to claim 1 is characterized in that, planting density is controlled as follows: about 6 seedlings of the every cave of hybrid rice, and every mu of 6000-8000 cave of single cropping hybrid rice, every mu of 8000-10000 cave of two season indica hybrid rices; The general every cave of japonica rice variety 6-8 seedling, every mu 8000 cave of large spike japonica rice variety or Japonica Hybrid, every mu 10000 cave of middle fringe type kind, every mu 12000 cave of spike number type kind.

3. method according to claim 1 is characterized in that adopting 3 to connect hole seedling dish and breed 3 and connect hole group rice shoot, and the severization control is also carried out drought pipe, length of time rice seedlings grow 25-30 days, average every seedling band tiller >=0.5.

4. method according to claim 1; It is characterized in that said three company's hole seedling dishes are a plurality of seedling pits that on seedling dish plane, are provided with; Each seedling pit bottom is provided with aperture, and per 3 of described seedling pit is seedling cave of one group of formation, and 3 seedling pits in each seedling cave are equilateral triangle and arrange; And the seedling pit in the seedling cave makes 3 seedling pit locally connecteds in each seedling cave in that the adjacent wall is recessed in twos.
