Embodiment 1

[0083] The dry direct seeding cultivation method of rice, the conditions and steps of the method are as follows:

[0084] Step 1. Dry land preparation

[0085] At the beginning of each year, mechanical force is used to melt snow and disperse moisture. Before sowing, rice field crushers are used to crush the soil at high speed, so that the maximum diameter of the top soil clods is 2 cm;

[0086] Step 2. Dry seeding and one shelling side deep fertilization

[0087] (1) The sowing period is selected when the ground temperature at 5 cm underground is stable at 8 °C,

[0088] (2) Soak the rice seeds in water at 10°C for 3 days after air drying, then sterilize them with soaking spirit, dry them in the air for 4 days after germination, and pellet them after root removal.

[0089] (3) Wide and narrow rows are used for close planting, the width of the wide row is 45 cm, and the width of the narrow row is 20 cm.

[0090](4) The rice dry direct seeding machine is used for sowing, the ...

Abstract

The invention relates to the field of rice cultivation methods and discloses a dry direct seeding cultivation method for rice. The dry direct seeding cultivation method for the rice comprises mechanically melting snow and dispersing moisture of the soil compulsively in old rice fields and preparing the soil by pulverizing through a rice field soil pulverizer in a high speed before seeding; deep applying 360 kg of prolonged and controlled release NPK (Nitrogen Phosphorus Potassium) compound fertilizer which is rich in microelement and has the effective dose of 50 %, 75 kg of diammonium phosphate or monoammonium phosphate and 18 kg of granular biological bacterial fertilizer to side positions 6 to 10 cm lower of rice seeds per hectare in one time and applying no fertilizer for the whole growth period; starting irrigating rice seedling at the rice period with four leaves and one center and manually replenishing water in the three water requirement critical period; weeding chemically; preventing and treating pest and disease damage; controlling rice blast. The dry direct seeding cultivation method for the rice has the advantages of solving the problems that the amount of labor used is large and the water is wasted during the rice cultivation process, increasing yield by 10 to 15 percent compared with water direct seeding, increasing yield by 5 to 10 percent compared with rice transplanting, being water saving, labor saving and mechanical in tilling, enabling tillering generation to be early and tillering number to be large, being good in soil permeability and enabling rice root system to be flourish.

Description

technical field [0001] The invention relates to the technical field of rice cultivation methods, in particular to a rice dry direct seeding cultivation method. Background technique [0002] my country is a water-poor country with a large population. The water used for daily life and industrial and agricultural production is constantly increasing, and the contradiction of water shortage is becoming increasingly prominent. In the Sanjiang Plain of Heilongjiang Province, two-thirds of the paddy fields are irrigated by well water. In the early 1990s, the depth of wells drilled did not exceed 20 meters, which was enough for centrifugal pumping on the ground. In the past 10 years to 2000, the depth of wells has reached Increase it to 70-100 meters, and replace it with a submersible pump. If things go on like this, the excessive overexploitation of groundwater will have unimaginable consequences. The Sanjiang Plain, which is very rich in water resources, can completely replicate th...
