Key points of cultivation techniques and cultivation management of alfalfa in Xinjiang
In Xinjiang, red carp is generally cultivated. The red carp has relatively strong adaptability. The requirements for soil sac are not particularly high. They also have strong resistance to mites and drought tolerance, even in sandy soil sacs. As long as the ventilation is good, it can always grow. Therefore, strengthening the implementation of the cultivation and cultivation techniques of Xinjiang carp has a special role in improving the mass production in Xinjiang.
1 Site preparation
Before carrying out cultivation and planting in Xinjiang, it is necessary to do the relevant work, such as land selection and land preparation work. If conditions permit, it is necessary to select a section where the terrain is relatively flat and the soil pocket is loose. This is to fully guarantee the sunshine. Sufficient and easy to irrigate. In addition, after the sandbag soil is deeply turned over, it is necessary to carry out the necessary fertilization of the soil bladder. Under normal circumstances, the amount of fertilizer per acre of land needs to be above and below 1600 kg. After the flattening treatment, it is made into a standard width crucible.
2 æž¸æž seedlings
There are many known methods of breeding cockroaches, including seeding, ramets and cuttings. In terms of seedling growth of alfalfa seeds and the actual climate of Xinjiang, spring sowing is the most suitable sowing and seedling time in Xinjiang. At the same time, the dried fruit is placed in the edema for about 30 hours before sowing, and the flesh and peel are removed. In the clear water, the alfalfa seeds are effectively rinsed, and then dried out. After the seeds are fully dried, they are thoroughly stirred with the standard fine sand, and then placed in a standard room temperature environment for germination. After the whitening, the germination seeds are planted in the appropriate fine soil in the nursery ditch. After the soil is covered 2cm, the appropriate force is used to step on it. In addition, the watering work is required at the same time. Planters should pay special attention to the fact that cockroaches should be watered as much as possible before seedlings, which can provide sufficient water support for seedling growth, but in the later stage, it should be done without watering or watering. In order to make the seedlings form a lignification.
It should be specially pointed out that the effective development of the seedling operation is often carried out in the case of a seedling height of 20 cm or more, and the seedlings are controlled to be 12 cm or so. In this process, the actual growth of the seedlings is required to be carried out seriously and effectively. Analysis, in the case that the root length of the rhizome reaches more than 0.6 cm, it is necessary to pay attention to transplanting. In Xinjiang, cutting seedlings are an extremely important process for raising seedlings. The relevant planters must select the long branches of the branches before they sprout in the spring, and cut them into relatively standard 15cm long cuttings. It is guaranteed that there are multiple buds on all the inserts. In this process, the upper end of the insert is cut into a flat mouth, and the position of the lower end is cut into a slanting opening, so that the cutting operation can be smoothly and effectively implemented, and the insert is required. Placed in a standardized dose of rooting powder solution, the actual need to soak for 24 hours, the purpose is to enable rooting of the cuttings. After the end of the soaking work, the cuttings are obliquely inserted into the seedbed according to the standard row distance, in order to effectively promote the true survival of the seedlings.
In Xinjiang, China, the transplant of alfalfa seedlings is normally in the late spring of March or the end of April, and of course it can be mid-autumn or late in the fall, during which the seedling transplant can be maximized. Ensure the survival rate of the transplant. When carrying out the transplant operation, the large hole treatment should be carried out according to the standard hole distance to ensure that three seedlings can be accommodated in each acupoint, and the distance between the seedlings in the acupoints is controlled at 35 cm, and appropriate trampling is required after the end of the transplanting work. Irrigation treatment, which can maximize the survival of seedlings.
3 æž¸æž cultivation techniques
In Xinjiang, after the planting of the bud, generally June is the period of new shoot growth. Because the new shoots need sufficient nutrients and water support during the growth process, it is necessary to do a special topdressing and watering work in the process, so that the eucalyptus seedlings can Normal growth and development. In addition, it is necessary to pay special attention to the need to carry out top dressing and watering work in October and November, so as to provide the best cultivation conditions for later cultivation and seedling raising. The watering work in this process is not carried out blindly. It should be combined with the weather and the actual conditions of the soil bag to carry out reasonable and effective irrigation and drainage, to avoid the unreasonable humidity of the soil bag to the utmost extent, if the humidity is too large or too small May directly affect the final cultivation effect.
It should be pointed out that when planting hoes, it is necessary to carry out the necessary management of planting soil sacs or planting fields. The relevant planters need to do the cultivating and weeding work in a timely and effective manner to avoid problems such as weeds in the field to the utmost extent. If too much weeds directly or indirectly affect the absorption of nutrients by cockroaches, it is necessary to intervene in the process of topdressing the seedlings. The new planting of saplings is a more important and complicated task. In general, the actual choice of drying will be at a dry height of 62 cm, and it is necessary to make reasonable reservations for the side branches. This is to ensure the dry effect. In the second year and the fourth year of the growth of the dragonfly, the upper canopy can be formed in a true sense. After so many years, the eucalyptus can be basically formed. Therefore, it is necessary for the workers to carry out the necessary repairs and finishing of the canopy crown regularly or irregularly, and cut off overlapping branches, dead branches and pests and diseases. The eucalyptus seedlings can achieve good ventilation and light transmission, and finally promote the healthy and stable growth of the eucalyptus seedlings.
It should be noted that in the topdressing, it is necessary to carry out scientific and reasonable topdressing in combination with the actual situation of the Xinjiang soil sac and the climatic conditions. For the cockroaches, due to the relative investigation of the flowering and fruiting period, and at the same time licking the fertilizer, it is in the germination stage. In the flowering period or in the fruiting period, the topdressing work should always be adhered to. In the seedling stage, the topdressing should be based on the actual situation three times. At the same time, in the vigorous period of the flowering result, the topdressing should be applied twice, and the topdressing fertilizer is generally the ammonium phosphate compound fertilizer. In the end of October or early November of each year, it is possible to carry out ditching treatment on both sides of the eucalyptus root, apply certain organic fertilizer in the ditch, and cover the soil for watering treatment, so as to maximize the yield of alfalfa. In addition, during the day, the car generally needs to be controlled at 15 °C - 20 °C, while the temperature at night needs to be controlled at 10 °C. If the car is greater than 25 °C, necessary ventilation and cooling are required. Before the germination of spring every spring, it is necessary to combine the actual conditions of the soil sac to carry out the cultivating and loosening soil treatment. In addition, it is also possible to topdress the fermented pig manure or human excrement in order to maximize the nutrition of the soil sac and to grow the sputum. Great help. After fertilization, the soil is covered and the water is sprayed at the same time. The watering work should be analyzed according to the specific conditions of the climate and the actual situation of the soil bag, and targeted treatment. Generally, it is necessary to adhere to the method of small water pouring, and at the same time, it is necessary to keep the soil bladder moist enough. This is to minimize the problem of flooding and to minimize the ground temperature.
