Description

A kind of direct sowing of rice field planting method suitable for strand shallow lake slurry type aleuritic texture salt-soda soil
Technical field
The present invention relates to a kind of rice growing methods, and in particular to a kind of suitable for strand shallow lake slurry type aleuritic texture salt-soda soil Direct sowing of rice field planting method.
Background technique
Strand shallow lake slurry type aleuritic texture salt-soda soil is because soil organic matter content is extremely low, and soil aggregate structure is not formed, therefore Workability of soil is poor, has been not easy to starch and precipitate after rotary tillage to be exceedingly fast, it is just completely hardened that extreme place water is threaded through half an hour after.
Currently, the rice conventional seed planting technology that strand shallow lake slurry type aleuritic texture salt-soda soil uses, mainly there is rice transplantation by hand, the machine transplanting of rice Seedling, water direct seeding, direct-sowing dry etc., but difficulty of transplanting seedlings is big, and survival rate is low;And be broadcast live because rotary tillage can not be slurried, seed is exposed to after broadcasting Earth's surface is easy to appear lodging after making rice that can not normally found seedling or vertical seedling, effect is all not so good without effectively covering.
Summary of the invention
The purpose of the present invention is to provide one kind can for can not be slurried after the type aleuritic texture salt-soda soil rotary tillage of strand shallow lake slurry, Without effective the problems such as covering, it is fixed after planting to provide a kind of direct sowing of rice suitable for strand shallow lake slurry type aleuritic texture salt-soda soil for seed Plant method.
The present invention is implemented as follows:
A kind of direct sowing of rice field planting method suitable for strand shallow lake slurry type aleuritic texture salt-soda soil, includes the following steps:
Step 1: ploughing, alkali drops in the water inlet soaked field desalinization of soil by flooding or leaching
It is ploughed before Rice Cropping, rotary tillage depth 15cm, drops alkali using the desalinization of soil by flooding or leaching of fresh water soaked field, be down to surface soil salinity not high In 3 ‰, substantially meets rice and found seedling growth demand;
Step 2: applying organic manure, rice seed soaking vernalization
It is synchronous to carry out rice seed soaking vernalization by applying organic manure, tentatively improvement soil texture;
Step 3: rotary tillage is sowed after striking off
Reach sowing condition after accelerating germination of rice seed, when temperature is stablized at 15 DEG C or so, first use tractor band rotary cultivator rotary tillage, Then it is and then struck off with tractor band Slicking apparatus, throwing fertile all-in-one machine using the sowing of tractor band in 30 minutes after striking off will be through vernalization Rice paddy seed afterwards is sowed;
Step 4: later period field management
The silt soil that one layer of mud deposits can be covered after rice paddy seed is broadcast, on seed, it is ensured that ground moistening, without chap It splits, surface layer 15cm soil salt is observed using soil salt tacheometer daily, if salinity is higher than 3 ‰, shallow water frequent irrigation is frequently changed, if Upper soll layer salinity is lower than 3 ‰, guarantee ground moistening, without chap under the premise of, into shallow water moisturizing within 3 days, it is ensured that rice It is normal to be colonized vertical seedling.
Further scheme is:
The fresh water refers to salt content in 3 ‰ fresh water below.
Further scheme is:
Alkali drops in the desalinization of soil by flooding or leaching of fresh water soaked field, carries out at least once, until surface soil salinity is down to not higher than 3 ‰.
Further scheme is:
Topsoil refers to the soil of skin depth 15cm or more.
Further scheme is:
Organic fertilizer is the cow dung of water content 60%, applies 2 tons of cow dungs per acre, and organic fertilizer is sprinkled into field in such a way that throwing is applied.
Further scheme is:
Tractor is 1304 tractors.
Further scheme is:
In step 3, tractor band rotary cultivator rotary tillage, rotary tillage depth is 15cm.
Further scheme is:
Fertile all-in-one machine is thrown in sowing, is with the throwing fertilizer machine for throwing kind of subfunction.
Further scheme is:
Shallow water refers to depth of water 5cm.
The present invention is turned over rotation using rotary cultivator and is improved shallow lake slurry type flour sand using tractor band rotary cultivator and tractor band Slicking apparatus The suspension fusion amount of matter soil recycles Slicking apparatus to arrange stirring mud suspension, prevents water and soil quick separating.Then using dilatory Fertile all-in-one machine is thrown in the sowing of machine band, the rice paddy seed after vernalization is sowed before mud does not separate, using suspension puddled soil by rice Seed covering.Seedling is normally found after realizing shallow lake slurry type aleuritic texture rice in saline-alkali field direct-seeding planting and improves rice seedlings lodging tolerance.
Specific embodiment
The present invention is further illustrated combined with specific embodiments below.
A kind of direct sowing of rice field planting method suitable for strand shallow lake slurry type aleuritic texture salt-soda soil, includes the following steps:
Step 1: ploughing, alkali drops in the water inlet soaked field desalinization of soil by flooding or leaching
Heavy salinized ground soil salt content in strand is up to 20 ‰, needs to be ploughed before Rice Cropping, rotary tillage depth 15cm, into excellent Alkali drops in matter fresh water (3 ‰ or less) the soaked field desalinization of soil by flooding or leaching, drops alkali by 1-3 (desalinization of soil by flooding or leaching number can be determined according to desalinization of soil by flooding or leaching effect) desalinization of soil by flooding or leaching, can So that surface soil salinity is down to 3 ‰, rice can be substantially met and found seedling growth demand.
Step 2: applying organic manure, rice seed soaking vernalization
Strand shallow lake slurry type aleuritic texture soil, 90% or more soil belong to chiltern matrix, it is 30 minutes most fast after band water rotary tillage within meeting There is water and soil separation, and silt acceleration precipitates, is hardened.By applying organic manure (2 tons of cow dungs per acre, water content 60%), tentatively Improve soil texture, it is synchronous to carry out rice seed soaking vernalization.
Step 3: rotary tillage is sowed after striking off
Reach sowing condition after accelerating germination of rice seed, when temperature is stablized at 15 DEG C or so, with 2 1304 tractors band rotary cultivators + 3 1304 tractors band Slicking apparatus, turn over the suspension fusion amount that rotation improves shallow lake slurry type silt soil using rotary cultivator, recycling is scraped Flat machine arranges stirring mud suspension and strikes off soil in favor of into draining and prevent water and soil quick separating.
It strikes off to be sowed in 30 minutes with 1304 type tractor bands in rotary tillage and throws fertile all-in-one machine, will be urged before mud does not separate Rice paddy seed after bud is sowed, is covered rice paddy seed using suspension puddled soil.
Step 4: later period field management points for attention
The silt soil that one layer of mud deposits can be covered after rice paddy seed is broadcast, on seed, it is ensured that ground moistening, without chap It splits, surface layer 20cm soil salt is observed using soil salt tacheometer daily, if salinity is higher than 3 ‰, shallow water (depth of water 5cm) is diligent Fill diligent to change, if upper soll layer salinity is lower than 3 ‰, guarantee ground moistening, without chap under the premise of, into shallow water moisturizing within 3 days, Ensure that rice is normally colonized vertical seedling.
Although reference be made herein to invention has been described for explanatory embodiment of the invention, and above-described embodiment is only this hair Bright preferable embodiment, embodiment of the present invention are not limited by the above embodiments, it should be appreciated that those skilled in the art Member can be designed that a lot of other modification and implementations, these modifications and implementations will fall in principle disclosed in the present application Within scope and spirit.
