Problems solved by technology

Each of these planting methods has its own advantages and disadvantages: manual transplanting is labor-intensive, and manual throwing, mechanical transplanting and mechanical throwing can all reduce labor intensity, but the requirements for paddy field preparation are relatively high, and the land must be as flat as possible. The growth period of rice is longer, and the selection of rice varieties with a short growth period in Shandong and other rice and wheat double-cropping areas is an obstacle that limits its development.
Among them, the seedling raising process includes four production steps of selection and treatment of improved seeds, seedbed making, sowing, and seedbed management; the transplanting process includes five production steps of whole field without water, making nests, fertilizing, transplanting, and watering roots; but The planting process of this patent is all manual, which is not suitable for large-scale mechanized production and application, and cannot be well adapted to mechanized assembly line production, with high cost and low efficiency
At present, there is no planting method suitable for large-scale mechanized dry seedling planting for rice

Embodiment 1

[0040] A rice mechanized dry seedling planting method, comprising the following steps:

[0041](1) Seedling raising: use plugs for seedling raising. The plugs include a tray body and a pot body. The pot body is a rounded platform body, and the pot body is located in the tray body. cm, the height of the pot body is 2cm, and the bottom surface of the pot body is provided with a permeable hole with a diameter of 4mm, such as Figure 1-2 As shown, seedling soil and rice seeds are sown in the pot body, 5-8 seeds are sown in a single pot body, and the seedling age of the seedlings is 20-30 days; It is convenient for mechanical sowing, and every 100 kg of seedling soil is mixed with 0.1 kg of nitrogen, phosphorus and potassium ternary compound fertilizer;

[0042] (2) Soil preparation: After wheat or rapeseed is harvested, apply rice base fertilizer, 50kg of rice base fertilizer per mu of land, and rotate the land to make ridges; Rotate the land to make the soil as fine as possible ...

Embodiment 2

[0046] A rice mechanized dry seedling planting method, the steps of which are as described in Example 1, the difference is that further, in step (1), after sowing seedling soil and rice seeds in the pot body, a cover is erected on the plug The plastic film keeps warm and moisturizes. After covering the plastic film for 2 days, remove the film and pour water every day to keep it moist. After pouring water, cover it back with the plastic film. The action of peeling off the film and watering is maintained until 2 days before the mechanical dry planting of seedlings. Do not pour water about 2 days before mechanical dry planting. If it rains 2 days before mechanical dry planting, the hole tray should be covered with plastic film so that the soil in the seedling cup is moderately dry and dry during mechanical dry planting. It is easy to separate seedlings, transport seedlings and mechanical dry transplanting operations, and make the mechanical dry transplanting of rice seedlings sta...

Embodiment 3

[0048] A rice mechanized method for planting seedlings in dry weather, its steps are as described in Example 1, the difference is that in step (3), the number of the groove-pressing wheels is at least two, and the distance between adjacent two groove-pressing wheels is 20cm. The spacing between the two ditching wheels is 20cm, so that the row spacing between the ditch after ditching is 20cm.

Abstract

The present invention relates to a mechanized dry transplanting method for rice, and belongs to the technical field of cultivation for agricultural crops. The method comprises the following steps: (1) seedling raising: adopting a plug for seedling raising, wherein the plug comprises a plate body and a bowl body, the bowl body is an inverted circular truncated cone which is located in the plate body, seedling culturing soil and rice seeds are inserted into the bowl body, and the seedling age of the seedling is 20-30 days; (2) soil preparation: after wheat or rapeseed is harvested, applying a rice basal fertilizer, carrying out rotary tillage on the land and preparing the furrow ridge; (3) dry transplanting: adopting a dry planting machine for rice provided by the present invention for transplanting, wherein the dry planting machine for rice comprises a driving apparatus, a seedling placing platform, a seedling separating track, a press wheel and at least one soil cover mechanism, as the rice dry planting machine constantly marches forward, the seedling constantly falls into a ravine and the ravine is filled by soil; and (4) irrigation: in 2 to 3 hours after the rice seedling is dry transplanted, irrigating water to prevent the seedling from being sunburn. According to the method provided by the present invention, mechanized operation for dry transplant for rice can be realized, so that the method is applicable to large-scale production application, low in cost and highly effective.

Description

technical field [0001] The invention relates to a rice mechanized dry planting method, which belongs to the technical field of agricultural crop cultivation. Background technique [0002] Rice is the main food crop in my country, and its planting area and output both rank second. my country has a long history of planting rice. Rice was planted in the Xia Yu era more than 4,000 years ago. The rice planting method in my country generally adopts the paddy field transplanting method, and the main transplanting methods include manual transplanting, manual throwing, mechanical transplanting and mechanical throwing. In recent years, dry live broadcast and water live broadcast have also been adopted. Each of these planting methods has its own advantages and disadvantages: manual transplanting is labor-intensive, and manual throwing, mechanical transplanting and mechanical throwing can all reduce labor intensity, but the requirements for paddy field preparation are relatively high, ...
