Description

TECHNICAL FIELD

[0001] The utility model relates to agricultural drip irrigation fertilization equipment technical field, especially a kind of difference zonally irrigated fertilization system of seed corn. BACKGROUND

[0002] Seed corn water-fertilizer integrated technology is a kind of efficient water-saving irrigation and scientific fertilization technology developed on the basis of conventional crop water-fertilizer integration. But seed corn is different from traditional crop cultivation of simultaneous sowing and simultaneous harvesting, and also different from traditional intercropping drip irrigation with the same crop on both sides. At present, seed corn is generally planted in 1:7 mode, i.e. 1 row of male parent and 7 rows of female parent, 1 pipe 2 row mode, i.e. 1 drip irrigation belt pipe and 2 rows of corn, male parent and female parent are sowed at different times, male parent is harvested before pollination, and female parent is harvested after seed maturation. Therefore, when the female parent sowed in advance is irrigated, the soil moisture content of the row where the male parent is not sowed will increase, which will affect the mechanical operation when the male parent is sowed. But the soil moisture content after the irrigation of seed corn cannot completely meet the emergence of the male parent, and if the soil is irrigated, the soil moisture content of the female parent row will be too high, which will reduce the soil temperature and affect the growth of the female parent, and even cause lodging in the later period. If the soil is not irrigated in time, the soil moisture content of the male parent row cannot meet the seed germination of the male parent, which will cause uneven emergence and affect the pollen amount in the later period, thereby affecting seed pollination and restricting the development of seed corn industry. Due to the problems such as different sowing and irrigation periods of male parent and female parent, the yield of conventional corn is generally 15000-20000 kg / hm 2 at present, the yield of seed corn is still less than 8000 kg / hm 2 . In the prior art, neither single irrigation system nor double irrigation system can completely meet the zonal irrigation and fertilization of seed corn, which will cause weak growth or poor emergence rate of male parent or female parent, and cause waste of water and fertilizer.

The single male parent drip irrigation tape 1 is connected to the male parent irrigation branch pipe 4, and the single female parent drip irrigation tape 2 and double female parent drip irrigation tape 3 are connected to the female parent irrigation branch pipe 5. The male parent irrigation branch pipe 4 and the female parent irrigation branch pipe 5 are connected to the existing irrigation network of the farmland through a water distribution valve 8, and a main control valve 9 is provided between the water distribution valve 8 and the existing irrigation network of the farmland.
