Tien Giang applied flattening fields with lasers

In the early summer-autumn crop of 2014, Tien Giang province supported three agricultural production cooperative groups of Binh Nhi, Vinh Huu communes (Go Cong Tay district) and Binh Phuc Nhut (Cho Gao district) equipped with three leveling machines Laser fields with a total investment of about 1.5 billion VND.

Among these, the laser leveling system alone costs about VND 300 million / machine, the rest is tractors with a capacity of 60 Hp or more per machine.

According to Tien Giang Agricultural Extension Center, a compact laser leveling machine system , including only bucket bucket, laser generator, signal receiver and hydraulic control system mounted on the tractor (type of machine that is popular in the southern field).

When operating this system, the laser beam emitted by the laser signal generator forms a fixed laser reference plane parallel to the horizontal plane. The laser signal receiver is fixed on the bucket. Hydraulic system consists of received signal processing box and hydraulic cylinder to help control the lifting of dandruff.

When operating, the bucket is automatically raised or lowered compared to the standard surface when the system works on the corresponding point is the high point or low point of the field.

Technical staff of Tien Giang Provincial Extension Center recommends, in order to carry out the leveling of the field by laser beam, the field needs to burn off the straw, plow the soil, dry the soil before leveling from 2 -3 days.

The survey results show that the flattening of the field by laser production costs decreased from 2-2.5 million VND / ha / crop thanks to increased rice productivity, cost savings for irrigation pump, easy control of weeds , reducing the amount of seed and labor, limiting pests and diseases, actively managing the fields well in the process of cultivation as well as harvesting .

With the cost of leveling from 3-4.2 million VND / ha depending on the reality, after 2-3 production seasons, the field owners return the capital to rent a leveling machine with laser beam and after a three-year cycle (6-9 cases) production) only need to level the second time. Thus, the profit from rice cultivation increased.

Due to the first time the laser leveling machine was put into operation in the field, the Provincial Agricultural Extension Center has transferred technology, organized demonstration sites as well as strengthened propaganda and introduction to farmers. people understand the benefits of bringing advanced technology into production.
