The method comprises the following steps: 1, elaborate soil preparation; 2, timely sowing, and sowing quality improvement; 3, water and fertilizer management reinforcement; 4, chemical weeding; 5, pest control. By the adoption of the scheme of the method, it is facilitated to achieve the comprehensive mechanization and standardized planting, the labor force input is reduced, and conditions are provided for achieving reasonable close planting, a high yield and good harvest; in addition, a great amount of agricultural water is saved, and the production cost is reduced.
Description
Technical field
The present invention relates to technical field of crop cultivation, be specifically related to a kind of Novel rice dry sowing waterpipe seedling culture method.
Background technology
China is a poor-water country, populous, and people's daily life water and industrial and agricultural production water are on the increase, the contradiction of lack of water.In this case, develop light simple water-saving agriculture, reform paddy rice waterflooding cultivation method, carry out water saving kind of rice, development direct sowing on dry paddy field is produced, imperative.
Paddy rice originates in the torrid zone, subtropical mire area, and south China is one of original producton location of paddy rice.Owing to being in the result of growth and long-term natural selection under high temperature, many wet environment for a long time, paddy rice is defined and adapts to the habit that grows in water, so people utilize waterflooding method rice-cultivating habitually, this is traditional cultivation method that rice cropping is continued to use since the dawn of human civilization always.This cultivation method, shortcoming is that water consumption is large, and the phenomenon of wasting water is very serious, constrains the development of Rice Production.Theoretical research is verified with practice, and Rice Physiological needs water many unlike other cereal crop, and physiological water requirement just refers to the moisture being directly used in paddy rice normal physiological activity and keeping in plant body required for water balance.This is just reform paddy rice waterflooding cultivation, carries out direct sowing on dry paddy field cultivation and provides theoretical foundation.
Summary of the invention
For the above-mentioned problems in the prior art, the object of the present invention is to provide a kind of Novel rice dry sowing waterpipe seedling culture method, easy and simple to handle, under the prerequisite of Ensuring Food Safety, meet the demand reducing cultivation use water, improve grain yield.
A kind of Novel rice dry sowing waterpipe seedling culture method, comprises step as described below:
(1) meticulous wholely: keep careless light, Horizon, soil block in small, broken bits during whole ground, make top layer soil block maximum gauge be not more than 3cm, during whole ground, carry out ditching, managing moisture in the soil;
(2) begin sowing in good time, improve seeding quality: select April 20 to be sowing time to May 10, seeding method is program request, cave distance 13-22cm, every cave 3-5 grain, per hectare seeding quantity 60-75 ㎏;
(3) water and fertilizer management is strengthened: during fertilising, per hectare sulphur ammonium 825 ㎏, superphosphate 600 ㎏, potassium sulfate 150 ㎏, zinc sulphate 22.5 ㎏, wherein, phosphate fertilizer is all made base fertilizer holostrome and is used, and potash fertilizer applies with fetilizer for tillering, and nitrogenous fertilizer 40% is as base fertilizer, 40% phase beginning of tillering imposed, and 20% panicle spike primordium differentiation stage is used; Pour water when rice shoot 3-4 blade, when pouring water, adopt flood irrigation, slow method of filling with, after tillering regularity, keep Tian Tugan dry wet;
(4) chemical weed control: after planting 5-7 days, per hectare 60% butachlor ec 5250-6000ml is watered 750 ㎏ sprayings;
(5) extermination of disease and insect pest: tillering regularity and fringe phase respectively spray once anti-snout moth's larva medicament, and the heading initial stage sprays banded sclerotial blight medicament.
Preferably, plough the first furrow as a guideline with 2m during reason moisture in the soil in described step (1).
Preferably, in described step (2) after planting, when rice shoot grew to for 5 leaf phase, carry out filling the gaps with seedlings and make per hectare rice shoot reach 120-150 hectare;
Preferably, in described step (4), during water scarcity, per hectare adopts 60% butachlor ec 5250-6000ml to be watered 7.5 ㎏ and is made into mother liquor, then mixes thoroughly with 1200-1500 ㎏ thin sand and soil and evenly to spread fertilizer over the fields afterwards.
The invention has the advantages that, adopt rice direct-seeding, decrease the link of seedling, rice transplanting, thus save labour; Compared with traditional planting patterns, postpone sowing when avoiding lack of water and make the florescence meet the unfavorable conditions of low temperature, thus improve rice yield, realize grain and increase income; The area smooth in field, can round Realization mechanization, is conducive to normalization plantation, decreases labour and drop into, for rational close planting and high yield, good harvest provide condition; In addition, agricultural water can also be saved in a large number, reduce producing cost.
Embodiment
Be described further the present invention below in conjunction with specific embodiment, following examples can make those skilled in the art more fully understand the present invention, but do not limit the present invention in any way.
Embodiment 1:
A kind of Novel rice dry sowing waterpipe seedling culture method, comprises step as described below:
(1) meticulous wholely: keep careless light, Horizon, soil block in small, broken bits during whole ground, make top layer soil block maximum gauge be not more than 3cm, during whole ground, carry out ditching, managing moisture in the soil;
(2) begin sowing in good time, improve seeding quality: select be sowing time, seeding method is program request in April 20, cave distance 13-22cm, every cave 3-5 grain, per hectare seeding quantity 68 ㎏;
(3) water and fertilizer management is strengthened: during fertilising, per hectare sulphur ammonium 825 ㎏, superphosphate 600 ㎏, potassium sulfate 150 ㎏, zinc sulphate 22.5 ㎏, wherein, phosphate fertilizer is all made base fertilizer holostrome and is used, and potash fertilizer applies with fetilizer for tillering, and nitrogenous fertilizer 40% is as base fertilizer, 40% phase beginning of tillering imposed, and 20% panicle spike primordium differentiation stage is used; Pour water when rice shoot 3-4 blade, when pouring water, adopt flood irrigation, slow method of filling with, after tillering regularity, keep Tian Tugan dry wet;
(4) chemical weed control: after planting 5-7 days, per hectare 60% butachlor ec 5250-6000ml is watered 750 ㎏ sprayings;
