Rape cultivation method

Technical field

The invention relates to the field of agricultural planting, in particular to a method for planting rapeseed.

Background technique

Rapeseed has children on soils that are loose, fertile, high in organic matter, and rich in water and fertilizer. In the early stage of growth, rapeseed has a greater demand for nitrogen, phosphorus and potassium. Therefore, most people will apply a large amount of fertilizer for nutrient supplementation after planting rapeseed. However, chemical fertilizers tend to cause agglomeration of the land, making it difficult for some rapeseed buds to break ground and affect the germination rate of rapeseed.

detailed description

The present invention will be further described below in conjunction with the drawings and specific embodiments.

Referring to FIG. 1 and FIG. 2, a method for planting rapeseed according to the embodiment includes the following steps:

In step S1, the seed and the nutrient soil are mixed in a ratio of 1:3 to 1:5 by weight. The nutrient soil is composed of grass ash, black mountain mud and mixed in a ratio of 2:1 by weight. The plant ash is rich in nitrogen, phosphorus, potassium and the like, so that the seed is mixed with the nutrient soil and then sown, so that the seed can obtain sufficient nutrients when germinated. Moreover, the soil of the ash and black soil is relatively soft, and the seeds can be broken out after germination.

In step S2, the mixed seed and the nutrient soil are sown in a predetermined land, and seeded in a row or column arrangement, and the distance between each row or column is 15-25 cm. The predetermined land is in the shape of a mound that has been ploughed and used for sowing on the land, and adjacent mounds are arranged in parallel, and the spacing between adjacent mounds is 15-25 cm. The mixed seed and the nutrient soil are sown on a column of a column shape or a row shape at a weight of 0.2 g to 0.5 g each time.

In step S3, the seed is planted into a plant within a predetermined time, and when the plant grows to the first predetermined time, the top bud of each plant is removed for the first time. The predetermined time may be about 3-5 days. The first predetermined time period is when the main stem of the plant has 5-6 branches. Removal of the top buds at this point can promote the growth of plant branches.

In step S4, the top bud is removed a second time when the plant grows to the second predetermined time. The second predetermined time period is when each branch has 9-13 leaves. At this time, the number of flowering results on the branches and the main branches can be effectively promoted.

In step S5, the rapeseed is harvested after ripening.

As a preferred solution, between step S2 and step S3, step S6-step S8 may be further included: step S6, after the mixed seed and nutrient soil are sown in the predetermined land, respectively, the leaf is covered at the seeding position. loose. The larch has a thickness of 1-5% Meter. The larch can be used to protect freshly germinated rapeseed seedlings. Since the newly germinated rapeseed is relatively tender and easily damaged by impurities such as sand and sand, the laying of larch can make the seedlings of rapeseed interspersed in the larch, thereby reducing the damage of impurities such as sand and sand. When the seedling grows larch, its trunk It has been relatively strong and can resist the damage of impurities such as sand and sand. In addition, larch is also rich in elements such as nitrogen, phosphorus and potassium, which can provide nutrients for the growth of rapeseed.

In step S7, after covering the larch, the plastic film is covered at each seeding position. The plastic film is intended to maintain soil moisture and a suitable temperature.

In step S8, the film is removed before the top bud of each plant is removed for the first time. Specifically, the film can be removed when 1-5 leaves of the seedlings are worn out of the larch.

The germination rate of rapeseed is compared by a specific example: the same land is equally divided and labeled as A and B.

0.25 kg of seeds were uniformly mixed with 1 kg of nutrient soil in A land. An additional 0.25 kg of seed was sown in a conventional manner.

The row spacing of A land and B land is about 40cm, and the error can be ±1cm. Fertilize, irrigate and manage in the same way.

On the third day, the number of seedlings in A land was about 2,573, while the number of seedlings in B land was about 2,343. On the fifth day, the number of seedlings in A land was about 3,590, while the number of seedlings in B land was about 3,351. On the 8th day, the number of seedlings in A land was about 3890, while the number of seedlings in B land was about 3441. In summary, the germination rate of rapeseed is greater than that of traditional seeding by mixing seeds with nutrient soil and then sowing.

In addition, it is necessary to fertilize the rapeseed every predetermined time after the step S2 and to irrigate the land from time to time. The method of irrigation can be drip irrigation or flood irrigation.

As a preferred aspect, the present invention also provides a system and method for irrigating land with rapeseed. The system includes a water supply assembly 1, a humidity detector 2, and a controller 3. The water supply assembly 1 includes a water pump 11, a water supply pipe 12, and a water spray head 13. The water pump 11 is for supplying water of a water source to the water supply pipe 12, and the water is supplied to the water spray head 13 through the water supply pipe 12. The water jet head can spray the water out in a fan shape, so that the water obtained on the land is relatively uniform. The number of the water jet heads 13 is several, and the water spray heads 13 are disposed at the gaps of the rows or columns. For example, a plurality of water supply pipes 12 may be vertically disposed at a gap of rows or columns, and one to four water spray heads 13 may be respectively disposed at the top end of each water supply pipe 12. The humidity detector 2 may be a soil moisture sensor for collecting moisture values of the soil. The number of the humidity detectors 2 may be plural, for example, a humidity detector 2 is disposed at intervals of about 1-5 m on each column or row of mounds. The humidity detectors 2 are respectively connected in parallel to the bus and connected to the controller 3 via a bus. The controller 3 is for controlling whether the water supply unit 1 operates based on the humidity value of the humidity detecting sensor 2.

The control steps for irrigation can include the following:

Step A1 acquires the humidity value of the soil in real time; the process of obtaining the humidity value may include detecting the humidity value of the corresponding position by the humidity detector and transmitting the humidity value to the controller.

In step A2, it is determined whether the humidity value is within a preset range. The humidity value is the weight ratio of the weight of water per cubic meter of soil to the dry soil. The preset range may be 20-60%. After receiving the humidity value, the controller determines whether the humidity value detected by the humidity detector above 65% is within a preset range, or is greater than a preset range; or is smaller than a preset range. For example, if more than 65% of the humidity detectors detect the humidity value is full Within the preset range, the soil moisture is within the preset range, otherwise it is not within the preset range.

In step A3, if the result of the determination in step A2 is YES, the controller does not send any command to the water supply component, or sends a command to close the water supply component. Specifically, when the water supply assembly is in an inoperative state and the humidity value is within a preset range, the controller does not send any command to the water supply assembly. When the water supply component is in the water supply state and the humidity value is within the preset range, a command to close the water supply component is sent.

In step A3, if the result of the determination in step A2 is no, it is further determined whether the humidity value is greater than the preset range or less than the preset range, and if it is less than, the controller sends a start command to the water supply component through the water supply component. Irrigation of the land; if it is greater, an alarm is issued to remind the staff to drain the soil. When it is detected that the soil moisture value is greater than a preset range, the controller further detects whether the water supply component is in an operating state, and if so, sends a shutdown command to close the water supply component, otherwise no instruction is sent to the water supply component.

Various other changes and modifications may be made by those skilled in the art in light of the above-described technical solutions and concepts, and all such changes and modifications are intended to fall within the scope of the appended claims.
