A combined Chinese yam tuber growth groove arranged in a trench belongs to agricultural planting appliances, the Chinese yam tuber growth groove comprises a combination part, a space part and a base, the combination part is used for overlapping an upper Chinese yam tuber growth groove and a lower Chinese yam tuber growth groove, and the Chinese yam tuber growth grooves are combined to form a Chinese yam tuber growth space. According to the Chinese yam tuber growing device, Chinese yam tubers are separated from soil, occurrence of soil infectious diseases is avoided, growth resistance of the Chinese yam tubers is reduced, and the Chinese yam tuber growing device has the advantages that the Chinese yam tuber growing device is simple in structure, convenient to use and high in yield, and the yield of the Chinese yam tubers is increased. Chinese yam tubers grow in the shallow soil layer, the planting density is increased, the tower furrow phenomenon is avoided, the yield and quality of Chinese yams are improved, the plot planting limitation is overcome, the planting range is expanded, mechanical planting is achieved, and the income of farmers is increased.

This invention belongs to the field of maize planting technology, and discloses a high-yield maize planting method based on a combination of density and fertilization, comprising the following steps: S1, planting maize using a wide-narrow row planting method; S2, planting maize in wide rows... 2 Calculate the planting spacing for wide-narrow row planting method using formula s. 1 =(1 / ax) 1 )*666.7, calculate the original corn planting spacing x 1 , will x 1 and y 2 Substitute the value into x 2 y 2 / 2=x 1 Given a / 2, calculate the planting spacing x when using the wide-narrow row planting method. 2 S3. Based on the narrow row y in step S1 1 、wide line y 2 Plant spacing x 2 Plant corn; S4, apply base fertilizer and top-dress with nitrogen fertilizer. This invention can ensure that the space occupied by individual corn plants remains unchanged by adjusting the spacing between wide and narrow rows, thus overcoming the technical bottleneck of increasing plant density without reducing yield, realizing the logic and formula of plant spacing optimization, and thereby achieving an overall yield increase.

The utility model discloses a double-layer inclined directional cultivation mold for Chinese yam, and belongs to the technical field of agricultural cultivation. The cultivation mold comprises a planting groove, a fixed plate and a movable plate, wherein the planting groove is obliquely arranged; the fixed plate is fixedly arranged in the planting groove; the movable plate is clamped in the position, corresponding to the upper part of the fixed plate, in the planting groove; the U-shaped grooves are respectively formed in the fixed plate and the movable plate, are linearly distributed and are used for planting Chinese yams; the drainage pipes are fixedly arranged at the lower inclined ends of the planting grooves and are arranged corresponding to the U-shaped grooves; an adjusting assembly used for adjusting the opening size of the drainage pipe is arranged at the end, away from the U-shaped groove, of the drainage pipe. According to the double-layer inclined directional cultivation mold for Chinese yam, a double-layer planting structure is formed through the combined design of the fixed plate, the movable plate and the U-shaped groove, more Chinese yam plants can be planted on the land in unit area, the planting density is effectively increased, the land utilization rate and agricultural production benefits are improved, and the yield is increased without enlarging the area.

The invention discloses a bare seedling planting mechanism, a self-propelled bare seedling transplanting device and a self-propelled bare seedling transplanting method, solves the problem that a bare seedling planting mechanism in the prior art is low in response speed, and has the beneficial effects of improving the response speed and improving the adaptability of bare seedlings. A crank in the crank four-bar mechanism is connected with a power source and connected with a rocker through a connecting rod, a push-pull mechanism is supported on one side of the connecting rod, the push-pull direction of the push-pull mechanism is the same as the arrangement direction of the connecting rod, the output end of the push-pull mechanism is movably connected with one ends of two pull rods respectively, and a set angle is formed between the two pull rods. The connecting rod supports the first support, the first support rotatably supports the middle sections of the two clamping finger mounting arms, one end of each clamping finger mounting arm is hinged to the other end of the pull rod, the first bent position of each clamping finger mounting arm is hinged to the first support, and the end, away from the pull rod, of each clamping finger mounting arm is connected with the corresponding planting clamping finger.

The application discloses a dry land spring maize planting method and application, and relates to the field of agricultural technology. The method comprises the following steps: rotary tillage after spreading fertilizer on a planting site; land preparation before sowing and setting wide rows and narrow rows, and covering the wide rows with mulching film; planting on the wide rows after covering the mulching film; and laying soil moisture sensors. The fertilizer comprises a high-molecular water-retaining agent and a nutrient base. The dry-land water-saving and synergistic fertilizer is organically combined with the ridge and furrow rain collection and mulching technology. The ridge and furrow rain collection efficiently collects rainfall in the crop root zone, and the mulching film significantly reduces evaporation loss. The dry-land water-saving and synergistic fertilizer further absorbs and retains water, forming a complete water management system of "water collection, water retention and water supply", so that efficient collection and utilization of natural rainfall are realized, water and fertilizer supply are strengthened, and the planting density under limited water conditions is improved.
