(4) area a variety of disease pest Hun Fa respectively counts each amount mixing seed dressing or seed pelleting using the above fungicide and insecticide.
It can be sowed after mixing rear heap thoroughly bored 2~3 hours.
4. sowing
(1) date of seeding
Set broadcasts sowing stage of wheat should be generally most appropriate with 7~10 days japonica rice symbiosis phases depending on japonica rice harvest time, at most not
It to be more than 15 days.It is October 10 to October 31 according to Henan south area accumulated temperature situation interplanting throughout the year wheat suitable sowing date, most preferably
Date of seeding is October 15 to October 25, and from north, southward date of seeding can be postponed gradually.
(2) amount of broadcasting and seeding method
Set is broadcast since many reasons will lead to planting percent decline, to be increased application rate when sowing, to be made Basic Seedling than conventional
Cultivation, which increases by 10~20% or more, just can guarantee sufficient fringe.
Huaibei area of wheat set broadcasts wheat Basic Seedling 20~220,000/666.7m2.Huainan area of wheat set broadcasts wheat Basic Seedling 18~20
Ten thousand // 666.7m2, specifically the amount of broadcasting is determined according to the indexs such as mass of 1000 kernel and germination percentage, Seedling emergence rate.In 90% or more seed bud rate
When per acre application rate be 17.5kg or so.
In Luohe, interplanting on October 10~20,15 kg/666.7m of the amount of broadcasting2；
In Zhumadian, interplanting on October 21~31, the amount of broadcasting 17.5kg/666.7m2；
In Xinyang, interplanting on November 1~10,20 kg/666.7m of the amount of broadcasting2；
Two days 0.5 kg/666.7m of increase are generally often delayed later2The amount of broadcasting, seed bud rate lower than 90% and it is following when, it is appropriate to increase
Application rate, but the maximum amount of broadcasting is no more than 22.5 kg/666.7m2。
Seeding method is to broadcast sowing, and is uniformly spread on wheat seeds between rice and ridge before rice harves, requires when sowing ground wet,
Soil moisture content reaches the 90%~100% of field capacity, and soil moisture content is poor will to fill horse race water in advance.

Permeability；If straw is really excessive blocked up, influences and inhibit wheat seedling growth, and field management can not be carried out, it can be by extra rice
Grass is concentrated and is deposited in field somewhere or moves to outside field.
6. rice harves post-processes
Rice harves backsight soil moisture content plays good compartment ditch, gutter, Yao Gou (the soil trench digging segmentation rectangularity compartment block of bulk；Along
The ditch that the long side in every compartment is outputed is compartment ditch；The long native field in every compartment is ditched again cuts into several sections, these are used to crosscutting long compartment soil
The ditch on ground is known as waist ditch) and main drainage ditch, machinery trench digging and soil in ditch get rid of it is broken be uniformly sprinkling upon on the face of compartment, can be complete by seed
Covering, it is also possible to which farmyard manure is covered.General compartment face is 2 to 3 meters wide.Compartment ditch requires straight, flat, deep, narrow (20~25 lis deep
It is rice, 15~20 centimetres wide), plot it is big to open waist ditch (15~20 centimetres deep, 20~25 centimetres wide), plot surrounding opens gutter
(enclosing ditch), gutter will be deeper than compartment ditch, and compartment ditch will be deeper than waist ditch, and ditch ditch communicates, and reach bright water energy row, dark water energy filter, and rain stops field
Without bright water.
7. fertilising
Interplanting wheat fertilizing takes the mode of " having more meals a day but less food at each ", and total dose is according to wheat yield level and soil fertility level come really
It is fixed, fertilizer application amount slightly lower or close to the upper wheat conventional seed planting mode of production.
Even wheat seed with after 1~2 day spreads fertilizer over the fields 20kg/666.7m between japonica rice ridge after broadcasting sowing2Formula compound fertilizer (N:
P2O5: k2O=18:18:18) or 20kg/666.7m2Formula compound fertilizer (N:P2O5: k2O=15:15:15)+5 kg/666.7m2
