Embodiment 1

[0047] The dry direct seeding sprinkling irrigation cultivation method for rice in hilly and sloping land without grids of the present invention comprises the following steps:

[0048] Step 1. One-time preservation seedlings

[0049] The seeding depth is 2cm with a ditch-type seeder for sowing;

[0050] Step 2. Chemical weeding is carried out by adopting the method of killing one letter and one, treating early and treating small.

[0051] Sealing: After sowing and before seedlings, use 300 ml / mu of Zhongdingling to seal the soil;

[0052] Killing: When the seedlings grow to one leaf and one heart, use 34% propanil EC for spray treatment, and the dosage is 550 ml / mu;

[0053] Step 3. Apply fertilizers at the same time, no more topdressing after one-time fertilization

[0054] Apply diammonium phosphate at 2cm directly below the seed, and apply slow-release urea at 11cm diagonally below the seed;

[0055] Step 4. Sprinkle irrigation in the water-sensitive period, and water s...

Embodiment 2

[0058] The method for cultivating dry direct-seeding and spraying irrigation of paddy rice in hilly and sloping fields without grids of the present invention comprises the following steps:

[0059] Step 1. One-time preserved seedlings

[0060] Sowing was carried out with a pressure groove type seeder, and the sowing depth was 1cm;

[0061] Step 2: Chemical weeding by adopting the method of “one seal, one kill, early treatment and small treatment”

[0062] Sealing: before seedlings after sowing, use pendimethalin 250 ml / mu to seal the soil;

[0063] Killing: When the seedlings grow to two leaves and one heart, spray with 34% propanil EC at a dosage of 500 ml / mu;

[0064] Step 3: Fertilize the seeds at the same time, and do not top-dress after one-time fertilization

[0065] Apply heavy superphosphate at 1 cm directly below the seeds, and apply slow-release urea at 10 cm obliquely below the seeds;

[0066] Step 4: Sprinkle irrigation in the water-sensitive period, and water ...

Embodiment 3

[0069] The method for cultivating dry direct-seeding and spraying irrigation of paddy rice in hilly and sloping fields without grids of the present invention comprises the following steps:

[0070] Step 1. One-time preserved seedlings

[0071] Sowing is carried out with a pressure groove type seeder, and the sowing depth is 1.5cm;

[0072] Step 2: Chemical weeding by adopting the method of “one seal, one kill, early treatment and small treatment”

[0073] Sealing: before seedlings after sowing, use pendimethalin 250 ml / mu to seal the soil;

[0074] Killing: When the seedlings grow to two leaves and one heart, use 34% propanil EC for spraying treatment, and the dosage is 600 ml / mu;

[0075] Step 3: Fertilize the seeds at the same time, and do not top-dress after one-time fertilization

[0076] Apply heavy superphosphate at 1.5cm directly below the seeds, and apply slow-release urea at 12cm obliquely below the seeds;

[0077] Step 4: Sprinkle irrigation in the water-sensitiv...

Abstract

A dry direct seeding and sprinkling irrigation cultivation method of rice in hillside non-ridge fields relates to the field of rice planting and solves the problem that an existing rice planting process has high labor consumption and water waste. The method of the invention comprises: preserving whole seedlings at a time, and sowing to a depth of 1-2 cm; covering, to be specific, in post-sowing seedling stage, covering soil with 300 ml / mu of butralin or 250 ml / mu of pendimethalin; disinfesting, to be specific, when young seedlings grow with one leaf and one core or two leaves and one core, spraying 500-600 ml / mu of 34% propanil emulsifiable concentrate; applying both seeds and fertilizer, wherein no topdressing is applied after single fertilizer application; performing sprinkling irrigation in water-requiring sensitive stage, and applying water stress in other growth stages, wherein sprinkling irrigation is performed separately in the stage of seedlings growing with 4.5 leaves, the stage of seedlings growing with (N-n+1) leaves, the stage of seedlings growing with two inverted leaves, and the full heading stage, and sprinkling quantity is not less than the rainfall of 30 mm each time, wherein N refers to total leaf age, n refers to stem internode number, and n=N / 3. The method of the invention has low labor consumption and water consumption and provides improved quality.

Description

technical field [0001] The invention relates to the technical field of rice planting, in particular to a method for dry direct seeding sprinkler irrigation of rice in unchecked fields on hillsides. Background technique [0002] my country is a water-poor country with a large population. People's daily water use and industrial and agricultural production water continue to increase, and the contradiction of water shortage is becoming increasingly prominent. Taking the Sanjiang Plain of Heilongjiang Province as an example, two-thirds of the paddy fields are irrigated by well water. In the early 1990s, the depth of drilling a well was not more than 20 meters, which was enough for centrifugal pumping. In the past 10 years to 2000 The depth of the well was increased to 70-100 meters, and submersible pumps were replaced. Overexploitation of groundwater in the long run will have unimaginable consequences. The Sanjiang Plain, which is very rich in water resources, can completely repl...
