The test of lodging resistance is carried out to rice in the time quantum that predetermines in the growth process, and the result comparison of through the multiunit experiment obtains that the rice that sprays 49% chlormequat chloride lodging resistance is better, is fit for cultivating and promotes on a large scale.
In the experimental process, can make full use of planting equipment, when planting equipment used, at first put into the inside of bin 4 with planting board 5, demolish handle 6, lay the matrix that the seedling was used on the upper portion of planting board 5 afterwards, grow seedlings on the matrix. The required water and fertilizer are injected into the water tank 18 through the water inlet pipe 13 during the seedling raising process. Drive bin 4 through electronic slider 9 and reciprocate in the inside of water tank 18, and then make bin 4 different with the water depth of contact, and can adapt to the water of the different degree of depth, keep growing seedlings the in-process and have sufficient moisture and nutrient.
If the in-process of growing seedlings takes place to be exposed to the sun or insolate and chilly condition, with bin 4 downstream, and then plant the high decline of board 5, will shelter from curtain 28 and pull out from accomodating chamber 7, shelter from curtain 28 and expand in the top of planting board 5, and the handrail 26 at both ends passes through the magnet board bonding fixed, can keep shelter from curtain 28 and be in the state that expandes, shelter from curtain 28 can be at the top to plant the seedling on board 5 and hide the wind and keep off the rain, avoid solar insolate, can keep warm to it simultaneously, it is impaired to avoid the low seedling that leads to of temperature. The seedling raising in the water tank 18 can provide a good environment for seedling growth as far as possible, the adverse effect of seedling damage on subsequent experiments is reduced, the seedlings can be well raised in the water tank 18, and the seedlings can be consistent with those raised in a normal rice field in a natural state.
After the seedling is cultivated, install handle 6 at the top both ends of planting board 5, utilize handle 6 to upwards stimulate planting board 5 afterwards, take out planting board 5 and the seedling of cultivating, transplant the seedling afterwards. Before transplanting, the first slide rail 24 to be used is installed on the experimental site, and the experimental site can be selected to be a common farmland or an empty ground. And the planting frame 1 to be used is slidably mounted on the first slide rail 24 through the first slide plate 23. According to the grouping needs of experiment, divide into a set of with three planting frame 1 to the inlet tube 13 that will plant 1 side of frame in the same group communicates each other, makes the fertilization the same with adding water, and connects the installation through arm-tie 2 with two adjacent planting frames 1, makes the planting frame 1 in the same group gather together, is difficult for makeing mistakes in the experiment, improves the accuracy. Finally, soil required for planting the seedlings is laid on the planting plates 5, and the seedlings are transplanted on the planting plates 5.
During the seedling planting process, water and required fertilizer are injected into the water tank 18 through the water inlet pipe 13. And the depth of the rice seedling roots immersed in the water is controlled by adjusting the height of the storage box 4, so that the environment of the rice seedlings growing in the actual paddy field is simulated, the environment of the rice seedlings growing is the same as the external environment, and the accuracy of the experiment can be improved. If the seedling growth period needs to be drained, the water in the water tank 18 can be drained outwards through the drain pipe 3 during the field baking period.
Seedling growth in-process, when needing to spray insecticide, will spray insecticide the equipment bottom place inside the standing groove on second slide 34 upper portion, twist and move adjusting bolt 36 and drive push pedal 35 and fix the bottom of the equipment of spraying the medicine, promote the equipment that sprays the medicine afterwards and slide on second slide rail 32, can be fast even spray the seedling in the same group, spray more evenly. And in the spraying process of the medicine, the medicine between seedlings of different groups does not interfere. Seedlings not sprayed with the pesticide can be moved downwards to the inside of the water tank 18 and shielded above by the shielding curtain 28, so that other pesticide which is not applied is prevented from falling onto the seedlings, and the experiment of the subsequent seedlings is prevented from being influenced. When the lodging resistance of seedling in the follow-up artifical test growth process that needs, can fix the fan bottom of testing on second slide 34, promote the fan afterwards and remove on second slide rail 32, carry out the test of anti-wind ability to the seedling in planting, convenient and fast more during the test.
If flood occurs in rainstorm weather in the experimental process, the flood submerges the experimental place, gas can be filled into the air bag 17, and then the air bag 17 is unfolded below the planting frame 1 to play a floating role, so that the planting frame 1 can float in water. When the planting frame 1 floats and moves upwards, the elastic telescopic rod 19 extends upwards, so that the planting frame 1 can not be flushed away by flood, and the normal movement of the planting frame 1 in the vertical direction is not influenced. The safety in the seedling experimental planting process is ensured, the seedling experimental planting device is not easily influenced by the outside, and the experimental result is more accurate.
In order to have more comprehensive experimental data, the stem of the seedling can be intercepted to test the compression resistance. When the intercepting seedling, install cutting knife 29 in the one end of shielding curtain 28, with the height control of bin 4 to predetermined position, pulling shielding curtain 28 expandes afterwards, the cutting knife 29 of its tip can cut the seedling upper portion on planting the board 5, again afterwards with bin 4's height rising one section, pulling shielding curtain 28 once more, the cutting knife 29 of its tip can cut the seedling again, and then obtains the seedling stem stalk of segmentation. Through twice cutting, the cutting is more uniform and tidy, the lengths and the positions of the intercepted stem parts are the same, and therefore the accuracy of the experimental test is improved, and the working efficiency in the experiment is improved.
The preferred embodiments of the invention disclosed above are intended to be illustrative only. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. Obviously, many modifications and variations are possible in light of the above teaching. The embodiments were chosen and described in order to best explain the principles of the invention and the practical application, to thereby enable others skilled in the art to best utilize the invention. The invention is limited only by the claims and their full scope and equivalents.
