Description
Technical Field
The invention relates to the technical field of agricultural ecological planting, in particular to a method for planting crops in desert, and particularly relates to a method suitable for planting different crops such as rice, soybeans and the like.
Background
The land is thirsty due to desertification and is not suitable for cultivation, large-area desertification brings great harm to people, the problem of desertification is still a huge process at present, more and more people are actively put into the desert control at present, the desert control method mainly comprises the steps of controlling desertification by planting ecological forests, planting vegetation on the surface of the desert, stabilizing sand grains through root systems of plants after the vegetation survive, and preventing rainwater and wind from taking away the sand grains, so that a waterproof desertification control forest is formed. In order to further utilize desert resources, an attempt is made to plant rice in a desert at present, an impermeable layer is paved in a depth of 25-80 cm below sand, soil and base fertilizer are sequentially paved above the sand, a dike higher than the base fertilizer is arranged above the impermeable layer, a water storage sand field is formed by the impermeable layer and the dike, water is stored in the water storage sand field, and the rice is planted in the water storage sand field, so that the sand control can be realized, and the planting area of crops can be increased. However, such a technique has high cost, and especially for desert areas with serious water shortage, the operation difficulty is high, and the technique cannot be widely popularized.
For example, Chinese patent literature (publication date: 5/14/2019, publication number: CN 105900758B) discloses a method for planting rice in desert, which comprises the following steps: selecting varieties, raising seedlings, tidying land, preparing land, transplanting, fertilizing, managing water, preventing and controlling diseases and pests and harvesting. The biomass mixture is used for improving the soil of the desert plough layer, and the water retention, the nutrient content and the buffer capacity of the desert plough layer are improved; the degradable polylactic resin film is laid under sandy soil, and meanwhile, the surface of the soil is covered to reduce the evaporation of water in desert and improve the water utilization efficiency.
For another example, the chinese patent literature (publication No.: 2015, 3, 11, publication No.: CN 104396537 a) discloses a method for transforming desert by planting crops, comprising the following steps: s10, sowing crop seeds on the desert at proper intervals; and S20, covering the desert where the crop seeds are sowed with a mixture of animal excrement and waste plant fragments. According to the method for transforming the desert by planting the crops in the desert, the desert is transformed by covering the mixture of the animal excrement and the waste plant crushed aggregates, the desert can be changed into a fertile field, the crops can be planted in the desert, sand can be effectively fixed, and dust in the desert can be prevented. In addition, the method for transforming the desert by planting the crops in the desert can effectively utilize waste plant crushed materials, particularly plant straws, and reduce the burning treatment amount of the plant straws, so that the pollution to the environment caused by burning the straws is reduced.
In summary, although the prior art provides a planting method for desert rice and crops, the existing planting method has great limitations and is affected by the environment of a desert area, the existing planting is performed for single crops, for example, only for rice, so that the whole environment setting can only be based on rice in the implementation process, and obviously, in the desert area lacking serious conditions, the problems of high cost, strong pertinence, strong seasonality and the like can exist, and the corresponding seasons are passed, the desert needs to be vacant, and the desert is not beneficial to the farmland formation; gradual advancing to the desert cannot be realized so as to reduce the desert area.
Disclosure of Invention
The invention aims to solve the limitation of the existing desert crop planting, and provides a method for planting crops in a desert, which can adapt to the planting of different crops, can reasonably utilize the whole developed sand land, can plant the crops in different seasons and can continuously push the crops into the desert to realize the final purpose of changing the desert into a farmland, develops and utilizes desert resources to the maximum extent, improves the desert environment and realizes the soil transformation of the desert.
The invention adopts the technical scheme that the invention achieves the aim that: a method of growing crops in a desert, comprising the steps of:
s1, deeply digging the desert area to be planted to a depth of 30-80 cm, and flattening the sand below the deeply dug area by using a soil compactor to flatten the sand;
s2, performing anti-leakage treatment on the flattened sand;
s3, crushing the sand dug out in the step 1 into fine sand powder through a crusher, and adding an organic fertilizer mixture and planting soil into the fine sand powder to form plant planting mixed sand; backfilling the plant planting mixed sandy soil into the sandy land treated in the step 2 to form a planting sandy land;
s4, fixedly arranging solar power generation plates around the sand planting land formed in the step 3, and arranging a dehumidifier electrically connected with the solar power generation plates below the solar power generation plates;
s5, arranging a spray water replenishing pipe on the planting sandy land formed in the step 3, wherein the spray water replenishing pipe is communicated with the water source or the water supply source collected by the dehumidifier in the step 4;
s6, dividing a multi-block planting area on the planting sandy land;
s7, building a water fixing shed in each block planting area;
s8, selecting crops with different growth water requirements in the same season, and planting the crops at intervals in blocks;
s9, introducing irrigation water into the crop planting area with large water preference periodically, and planting the crops in blocks according to the planting requirements of the crops.
The method for planting crops in desert is characterized by improving desert in a pushing mode, carrying out sand digging treatment on a desert area to be planted, digging the desert to a depth of 30-80 cm, carrying out leak-proof treatment after flattening, then crushing dug sand by a crusher to form fine sand powder, then adding planting soil accounting for about 20% of the fine sand powder, adding an organic fertilizer mixture into the fine sand powder to form plant planting mixed sand, backfilling the plant planting mixed sand, flattening to form a planting sand, arranging solar power generation panels in blocks around the planting sand, arranging a dehumidifier below the solar power generation panels, generating power by utilizing solar energy, driving the dehumidifier to work, condensing water by a water source collected by the dehumidifier, discharging the condensed water to a spray water replenishing pipe, atomizing and replenishing water to the planting area by the spray water replenishing pipe, and naturally, when the water demand is great, the spraying moisturizing pipe communicates with the water supply source simultaneously to realize the regular moisturizing to crops. The planting method has the advantages that the planting is carried out on the planting sandy land in the divided blocks, the water fixing shed is arranged in the planting area for preventing the water evaporation of the desert, different crops are planted at intervals according to the amount of water preference, an internal ecological circulation system is formed when the sandy soil is planted in the whole block, the operation of the soil in the desert is realized, and meanwhile, the efficient planting of the crops is facilitated. The desert area is seasonal strong, and different crops can also be planted to the season that the crops that can plant the same season difference in different seasons, owing to set the internal circulation system to, the water source of planting utilization has also obtained effective control moreover, especially in the area of the serious lack of water in desert, has embodied its economic practicality more.
