on the basis of the machine of the first embodiment, the running direction of each conveyor belt 9 is consistent with the rotating direction of the furrow opener 2, the conveyor belt 9 for conveying soil 19 is partially divided into two sections with height difference, as shown in fig. 3, a high-level belt 16 close to the furrow opener 2 and a low-level belt 17 close to the seed sowing device 6 are respectively arranged, the front end of the high-level belt 16 is tightly attached to the furrow opener 2, the rear end of the high-level belt 16 is smoothly connected with the front end of the low-level belt 17 through a transition belt 18, and the rear end of the low-level belt 17 is provided with a rear soil discharger 8 for receiving the soil 19 conveyed by the low-level belt 17;

the front soil discharging device 5 penetrates through the low-level belt 17 and receives soil 19 thrown at the joint of the high-level belt 16 and the transition belt 18.

Specifically, soil 19 produced by soil cutting and ditching of the ditcher 2 is thrown to the high-level belt 16, the soil 19 conveyed by the high-level belt 16 is continuously moved to the transition belt 18, due to the height difference at the transition belt 18, the soil 19 is thrown out in a parabola shape, part of the soil 19 falls into the front soil discharger 5 below, the front soil discharger 5 discharges a first layer of soil 19, part of the soil 19 continuously moves to the low-level belt 17 leftwards under inertia, the soil moves leftwards under the transportation of the low-level belt 17 and is finally thrown to the rear soil discharger 8, and the rear soil discharger 8 discharges a second layer of soil 19.

Different crops and different periods of the same crop require different nutrients, so that a user can select corresponding nutrients 15 according to needs, and the nutrients are not limited to irrigation water spraying or liquid fertilization, but also can be granular fertilizers, or fertilizers or other substances in other forms which can appear in the future, and the like.

The biodegradable material, also called biodegradable material, refers to a material that can be completely degraded into low molecules under the action of natural microorganisms, such as bacteria, mold and algae, and the mechanism of biodegradation is roughly 3 ways:

the biological cell growth causes the mechanical destruction of the substance;

the action of microorganisms on polymers produces new substances;

the direct action of the enzyme, i.e. the microorganisms attack the high polymer leading to lysis.

It is generally believed that the biodegradation of polymeric materials occurs through two processes. Firstly, microbes secrete hydrolytic enzyme to the outside of the body to be combined with the surface of a material, and the high molecular chains are cut off through hydrolysis to generate a compound with a small molecular weight less than 500; the degraded products are then taken into the body by microorganisms, and through various metabolic routes, are synthesized into microbial bodies or converted into energy for microbial activities, and finally converted into water and carbon dioxide.

At present, the biodegradable material belongs to a mature product, has a wide application range, and can be used in the fields of mulching films, packaging bags, medicines and the like. The method has the advantages that the biodegradable material is selected to prepare capsule-shaped particles for irrigation and fertilization, on one hand, the capsule is small in size, and reasonable capsules can be pre-embedded according to different crops or different growth periods of the crops to directionally irrigate the crops; on the other hand, the degradable capsule particles for irrigating the crops in a fixed time, a fixed amount and a fixed direction can be finally converted into water and carbon dioxide after being degraded, the growth of the crops cannot be influenced, and the environment cannot be polluted.

The biodegradable material is a mature product, and its specific preparation and ingredients are not protected by the present embodiment, which is merely used as a tool, and thus its specific ingredients and preparation processes are not described in detail herein.

The degradable capsule particle 10 works as follows:

firstly, putting corresponding degradable capsule particles 10 for irrigating crops in a fixed time and quantitative mode according to the characteristics of the crops after ploughing, and forming structures of the bottommost degradable capsule particles 10, middle-layer thin soil (soil 19), upper-layer seeds 21 and covering soil (soil 19) from bottom to top;

after the laying is finished, the degradable capsule particles 10 are decomposed in batches in different time periods through variable films with different thicknesses or different additives according to the growth characteristics of crops, and filling liquid containing nutrients suitable for various growth stages of the crops achieves the purpose of irrigating the crops after the degradable capsule particles 10 are decomposed;

and step three, after the irrigation is finished, the shells of the degradable capsule particles 10 are slowly decomposed, so that the growth of crops is not influenced, and the purpose of irrigating the crops regularly, quantitatively and directionally is achieved.

In the above steps, the film refers to the cover 11 or the bag body 12, and the split design is selected, on one hand, to conveniently package the nutrient 15; on the other hand, when putting into degradable capsule granule 10, lay through machinery or artifical batch, a large amount of degradable capsule granule 10 can take place to pile up certainly, and each degradable capsule granule 10 can take place to rub or extrude when piling up, in order to improve degradable capsule granule 10's intensity, avoids its a large amount of damages, prefers to regard it as split type.

The timed irrigation refers to irrigation of crops at a specified time, the capsule particles can be decomposed in different time by adjusting the thickness of the capsule particles, a certain amount of additives such as starch, cellulose, a biodegradation agent and the like can be added into the materials of the capsule particles, so that the stability of the capsule particles is changed, the degradation time under the natural environment is variable, and the purpose of batch irrigation in different growth periods of the crops can be achieved, specifically as follows:

if the crops A need to be irrigated after 1 month, capsule particles with the thickness of 0.07mm can be selected, the capsule particles can be decomposed after 1 month, the nutrients in the decomposed capsule particles irrigate the crops A, and the decomposed shells can be slowly degraded, so that the growth of the crops cannot be influenced;

if the crops B need to be irrigated after 2 months, capsule particles with the thickness of 0.1mm can be selected, the capsule particles can be decomposed after 2 months, the nutrients in the decomposed capsule particles irrigate the crops B, and the decomposed shells can be slowly degraded, so that the growth of the crops cannot be influenced;

crops C need to be irrigated after 3 months, capsule particles with the thickness of 0.2mm are selected, the capsule particles can be decomposed after 3 months, nutrients in the decomposed capsule particles irrigate the crops C, and the decomposed shell can be slowly degraded without affecting the growth of the crops.

The decomposition time corresponding to the thickness can be obtained through multiple tests, and different types of crops can be recorded through multiple tests.

Quantitative irrigation refers to irrigation of nutrients in a preset unit to crops, and specifically comprises the following steps:

for example, 1-3 liters of nutrients are required to be irrigated to each square meter of a certain crop every day, and then 26-30 degradable capsule particles per square meter of the crop to be irrigated need to be thrown under the crop after ploughing; also, if the crop requires different amounts of nutrients at different growth periods, different numbers of capsules can be dosed.

The above quantities are only examples, as the size of the degradable capsule particles can be changed according to actual requirements, so that the capacity of the nutrients stored in the capsule is different, and the specific quantities are given according to the size of the capsule particles and the quantity of the nutrients needed by the crops to be irrigated.

The directional irrigation refers to the directional irrigation aiming at different crops or different growth periods of the crops, and specifically comprises the following steps:

for different crops, different nutrients 15 are filled in the capsule body 12;

aiming at different growth periods of crops, different nutrients 15 are filled in the capsule body 12, and the thickness of capsule particles is adjusted, so that the capsule particles are decomposed and irrigated at different periods, namely the thickness and the different nutrients 15 act together to realize directional irrigation.

Cover 11 and capsule 12 are all made by biodegradable material, and the thickness of cover 11 is greater than the thickness of capsule 12, and the thickness of cover 11 is greater than the even distribution of capsule 12's thickness respectively.

Because when putting into degradable capsule granule 10, lay through machinery or manual work batch, a large amount of degradable capsule granule 10 can take place to pile up certainly, each degradable capsule granule 10 can take place to rub or extrude when piling up, in order to improve the intensity of degradable capsule granule 10, avoid being extruded or the friction damage, preferably the thickness of closing cap 11 is greater than the thickness of utricule 12, as shown in fig. 4, utricule 12 plays the effect that the parcel bears filling nutrient 15, closing cap 11 is then used for sealing closure utricule 12, because degradable capsule granule 10 also can put into the rotation in the in-process of depositing or putting, can not exist with a certain specific gesture, consequently, the thickness of closing cap 11 is greater than the thickness of utricule 12, when guaranteeing degradable capsule granule 10's sealing performance, also can play the effect of bearing nutrient 15 in utricule 12.

In order to ensure uniform stress on the degradable capsule particles 10 as a whole, in the present embodiment, the thickness of the cover 11 and the thickness of the capsule body 12 are uniformly distributed, respectively, as shown in fig. 4 and 5.

In this embodiment, degradable capsule granule 10, 86% all are by the gluey shell (utricule 12) of fixed thickness and constitute, play the parcel and bear the effect of filling liquid, 14% is variable thickness film (closing cap 11), adjust the water storage time of degradation time and then regulation water storage capsule through changing film thickness, specifically, when making degradable capsule granule 10, can regard utricule 12 as unified thickness, make different thickness with closing cap 11, according to the difference of crop, or the different growth periods of same crop, capsule 12 and the closing cap 11 that will be fit for thickness carry out the combination assembly, so as to reach different degradation time.

In order to avoid spilling or overflowing the nutrients 15 in the capsule body 12, the degradable capsule particles 10 are inevitably impacted during the packaging and transportation process, in this embodiment, there is a gap between the highest liquid level of the nutrients 15 packaged in the hollow capsule cavity 14 of the capsule body 12 and the inner surface of the cover 11 or the inner wall of the capsule body 12, as shown in fig. 4.

Even if the nutrient 15 in the degradable capsule particles 10 is impacted, a certain gap is formed for the impact of the nutrient 15 because the nutrient 15 is not filled in the capsule body 12, so that the buffer is increased, and the transportation is convenient.

The highest liquid level of nutrients 15 packaged in the hollow capsule cavity 14 of the capsule body 12 has a gap from the inner surface of the sealing cover 11 or the inner wall of the capsule body 12, the capsule body 12 is of a bag-shaped structure with a smooth surface and no edges and corners, the injection opening 13 of the capsule body is circular, and the shape of the sealing cover 11 is matched with the shape of the injection opening 13.

When putting into degradable capsule granule 10, lay through machinery or artifical batch, a large amount of degradable capsule granules 10 must take place to pile up, and each degradable capsule granule 10 can take place to rub or extrude when piling up, in order to improve the intensity of degradable capsule granule 10, avoids being extrudeed or the friction damage, and utricule 12 is preferably the bag-shaped structure who has smooth surface and no edges and corners.

Because utricule 12 is for having smooth surface and the bag-like structure of no edges and corners, therefore in piling up storage and transportation, smooth surface can reduce the frictional force between degradable capsule granule 10, can not take place wearing and tearing, has guaranteed the integrality of degradable capsule granule 10.

In a preferred embodiment of the present invention, the injection port 13 of the capsule 12 is circular, and the cap 11 has a shape matching the shape of the injection port 13.

Referring to fig. 4, the cover 11 is circular and is matched with the injection port 13 of the capsule body 12, and when the degradable capsule particles 10 are stacked, the planar cover 11 can conveniently overlap the degradable capsule particles 10.

However, the shape is not limited to the above shape, and other shapes such as an oval shape, a fusiform shape, etc. may be used as the degradable capsule particle 10.
