In order to ensure the quality of machine insertion, the technical work in the following aspects should be done when promoting the mechanized transplanting process:
First, the preparation of seedlings
(1) When the machine is inserted, the height of the seedlings is about 20cm, and 1.5 to 3 plants per square centimeter (paddy rice) are planted. The leaf color is slightly pale and upright, and the hand pressure is flexible. 1 to 2 days before machine inserting, use “Quick Killing Spirit†Emulsion 30~35ml to spray 40-60kg of water, and in the area of ​​rice stripe disease control should add 10% of “imidacloprid†EC 15ml, control the gray Hida's poisonous transmission harms, so that it can be transplanted with drugs.
(b) Regardless of the method of breeding, the width of the block should only be in the range of 27.5-28cm and the length of 58cm. The four corners must be perpendicular to each other without any defects. The day before transplanting, the dryness of the block should be checked. When transplanting, use the fingers to hold the subsoil. When the soil is too dry, when the soil is too dry, when the soil is too dry, the seedlings will spread easily, lose seedlings, and cause puddling: The soil with large soil moisture is easy to arch, and the amount of seedlings picked is too large to increase the number of plants per planting in the hole.
2. The preparation of Daejeon should be completed with basal fertilization. The field should be leveled and the difference between the fields should not exceed 3cm. After transplanting, the plant should be made to have inches of water: The fields should be clean and tidy, and there should be no debris: the topsoil should be moderately soft and fine, Rotten on the real, precipitation is not compacted, clear water is not muddy. For high density grasses such as barnyardgrass and barnyardgrass, the mud can be combined with mud sedimentation and pounding. After the mu is used, 60% “Butalate†EC 100ml or 25% “Emaoxing†EC 200ml is wetted. Earth 20-25kg evenly spread, after application, keep 7-10cm water layer for 3-4 days to kill the grass with pesticide, until the mud is completely precipitated, it can be inserted into thin water machine.
Third, the transplanter adjustment (a) 秧 needle two gap adjustment
1. The standard clearance on the side of the pin and rail socket is 1.3-1.7mm. When the gap does not match, loosen the rail adjustment handle slightly, adjust the rails left and right, and make the left and right gaps the same.
2. The gap between the needle and the seedling box and the standard clearance at the side of the seedling box is 1.5 to 2.0 mm. When the clearance does not match, loosen the fastening bolts of the seedling box and the seedling box to move the slide bar, and move the seedling box to the right or left. Adjust it so that the gap between the left and right ends is the same.
(2) Adjusting the planting distance of the transplanting plant The row spacing of the Dongyang PF455S rice transplanter is fixed at 30cm. Due to different soil fertility, different seedling quality and different planting time, the total number of holes per acre should be adjusted by pushing and pulling the operating lever. To achieve high production and stable production purposes. As shown below: Plant spacing (cm): 14.6 13 11.7 Plant spacing adjustment (position): Pushing the number of acres (10,000 holes): 1.4 1.6 1.8 The operation of the above-mentioned spacing distance control handle must be performed at a low speed of the planting arm.
(3) Adjusting the depth of transplanting The planting depth of rice transplanter should meet the requirements of agronomic production, and should reach “no drift, no shallowness, no changeâ€. The depth of the PF455S rice transplanter can be selected by changing the position of the depth-adjusting handle to select 4 gear positions (shocking upwards, and vice versa). The insertion depth can also be adjusted by replacing the 6 jacks on the floating board bracket.
(IV) Adjustment of the number of plants per hole Since the varieties of planted crops are different, the number of plants per hole is different according to the agronomic production requirements. In addition to changing the seed insertion amount to achieve the number of plants per unit area, the Dongyang PF455S rice transplanter can also be adjusted. Vertically take the amount of thorium and the amount of lateral feeding to adjust the area of ​​the maggot needle, thereby changing the number of plants per hole when the machine is inserted. The adjustment range of vertical picking amount is 8-17mm, totaling 10 stalls. Each time the first gear is adjusted, the change is 1mm, the handle is adjusted to the left, the amount of picking is increased, and the amount of picking is increased to the right. The amount of picking is reduced, and the “standard†position is taken. The seedling quantity is 11mm, which needs to be adjusted by taking the seedling caliper. The lateral feed rake adjustment device is set on the disk on the planting part support and is marked with “26, 24, 20†three positions, respectively indicating that the hopper moves “ 10.8mm, 11.7mm, 14mmâ€. The horizontal and vertical matching adjustment can form 30 different small block areas. The minimum area for picking is 0.86cm2, and the maximum is 2.38cm2. Generally, after the first horizontal transfer pin is fixed, use the handle to change the amount of vertical picking. According to this principle, the amount of earthworms can be adjusted to the density of seedlings that have been bred to ensure a reasonable number of seedlings per hole after machine insertion.
