Abstract

This invention relates to a technology for the cultivation of rice and crops of rice crop rotation under irrigation using rain-free wide-grip frontal machines. The purpose of the invention is to reduce the material and labor costs for the implementation of irrigation and increase the efficiency of use of sprinkler machines. In a method involving irrigating rice crops and associated crops on adjacent crop rotation fields using a wide-range sprinkler, first sprinkling of all the checks of the first crop rotation field, filled with rice, is performed, returning the sprinkler to the extreme check of the same floor. After this, the last check is flooded superficially and the other checks of the same floor and the second check of the adjacent crop rotation floor, which is occupied by accompanying crops, are irrigated by sprinkling at the same time with the return of the sprinkler to the subsequent check of the first floor. 1 il. w w fe

Description

This invention relates to a technology for the cultivation of rice and crops of rice crop rotation under irrigation using sprinkling machines of frontal action.

The aim of the invention is to reduce. the cost of watering and increasing the efficiency of sprinkler use.

The essence of the method is illustrated in the drawing, which shows irrigation cycles according to the proposed method.

Dozhdevalnaya machine type 1 Kuban at the beginning of irrigation is in the first check 2

the first crop rotational floor 3, it takes water from the irrigator 4, the checks are divided into crop rotation floor by line 5. The machine passes the first rut 6 through the rice field. In the second rut 7, it irrigates the checks 8 of the second crop rotation floor 9 occupied by the intermediate crop, then it is poured over the checks 10 at the subsequent rut 11 and 12.

A sprinkler machine 1 is placed on the extreme checks 2 of the first crop rotation field 3, occupied by rice crops. By moving the machine along the kart irrigator 4 in the direction of the dividing line 5 of the adjacent crop rotation fields 3 and 9, carry out Os 200

sequential sprinkling of the checks of the first crop rotation field 3 with an irrigation rate of 150-200 m3 / ha, and then returning the machine 1 to the extreme checks 2. The first rut (shuttle) 6 machines are carried out in 2-3 days taking into account the soil and climatic features. During this period, the rice seeds germinate, and their field germination is 75-90%, after which the extreme checks 2 of the first crop rotation field 3 are flooded with a layer of water of 5-12 cm and controlled by this layer in accordance with the technological regulation of rice cultivation of this variety to The growing season is full of ripeness.

Simultaneously with the flooding of checks, the second shuttle turn 7 of machine 1 is carried out, in which not only rice crops, but also extreme checks 8 of the second crop rotation field 9, occupied by alfalfa, are subjected to sprinkling. After returning the car to the first field 3, it is placed before the next pair of checks 10 prepared for flooding. Subsequently, the irrigation process is carried out in a similar manner, with during the races of 11.12 machines the increment of the sprinkling areas on the second field is carried out in proportion to the flooded areas of the first field.

The duration of the flooding of checks of the first floor is 17-21 days, which makes it possible to reduce the hydraulic module of the card irrigator by 1.32, 0 times. The rut length of the sprinkler was 2250 m, which corresponds to the length of the irrigator with a two-way command of the distributor,

Ф о рм ул а and з о б р r ete n and

The method of irrigating rice and related crops of rice crop rotation, including irrigating crops on adjacent crop rotation fields using a wide-grip frontal sprinkler and surface flooding of rice crops, characterized in that in order to reduce the cost of irrigation production and increase the efficiency of sprinkler usage , carry out sequential irrigation by sprinkling all the checks of the first crop rotation field with the return of the sprinkler to the first check for this

the same floor, after which the surface flooding of this check and sprinkling over the rest of the car of the remaining checks of this floor and the first check of the second crop rotation floor with the return

the sprinkler to the second check of the first floor, with simultaneous surface flooding of subsequent checks of the first floor, alternating with the simultaneous irrigation of the remaining checks of the same floor

and subsequent checks of the second floor by shuttle movement of the sprinkler.

Claims (1)

Claim A method of irrigating rice and associated rice crop rotation crops, including irrigation of crops in adjacent crop rotation fields using a frontal wide-angle irrigation machine and surface flooding of rice crops, characterized in that, in order to reduce the cost of irrigation production and increase the efficiency of using irrigation machines, successive irrigation irrigation of all the checks of the first crop rotation field with the return of the sprinkler to the first irrigation check of the same field, after which surface flooding of this check is irrigated and irrigation irrigation during reverse movement of the machine of the remaining checks of this field and the first check of the second crop rotation field with the return of the sprinkler to the second check of the first field, with simultaneous surface flooding of subsequent checks of the first field, alternating with simultaneous watering of the remaining checks of the same field and subsequent checks of the second field by shuttle movement of the sprinkler. > 9
