A, one trap lamp is installed according to every 20-30 mus of standard, and according to a sex attractant device per acre, to kill evil Worm selects Empedobacter brevis biological pesticide to prevent and treat rice leaf roller, snout moth's larva;
B, the false smut in ear period disease can be prevented and treated for 10-15 days before cut with " the phonetic glycosides element in well ridge " or " well wax bud ";Rice blast It is prevented and treated with " light-coloured vinegar " within 3-5 days before cut, spends 5-7 days and prevent and treat again once;
(6) it gathers in: after paddy is mature, manually being gathered in the fine day morning, dry, clean, be put in storage, store as required;
The barley cultivation concrete operations are as follows:
(1) variety adoption: feeding barley variety selects " raise and raise wheat No. 1 ", " rich No. 1 of salt ";
(2) the cray time is put in a suitable place to breed according to water in second year field, make barley long to 20cm height or so, to determine that barley is sowed Time;If field postpones upper water and puts lobster in a suitable place to breed, barley sowing time can accordingly be postponed;
(3) planting patterns and planting density arrangement: feeding barley sowing field can be beaten according to 20cmx15cm delays or by 20cm or so The planting tank that amplitude plays 3-5cm carries out artificial seeding, it is also possible to duplex-type seed planter sowing or artificial broadcast, for field is broadcast live, It first uniformly sows seeds, carries out shallow rotary tillage afterwards, rotary tillage depth 10-12cm holds " three ditches " successfully by wide 1.5-1.8 meters of furrow;
(4) application rate: feeding 14-16 kgs/acre of barley application rate;
(5) crop field is arranged requires with fertilising: before feeding barley sowing, applying 200 kilograms or so of organic commercial fertilizer per acre, then It is made into 2 meters or so wide furrow to wait sowing, to hold successfully " three ditches ", guarantee that stain drops in field drainage;
(6) it if after planting soil moisture content is poor for barley, can be made by way of pouring water and entering in ditch or poured with equipment for plant protection water spray Moisture in the soil guarantees the timely germination and emergence of barley seed;
