Description

Root fixing water for tobacco transplantation and tobacco transplantation method based on root fixing water
Technical Field
The invention belongs to the technical field of tobacco cultivation, and particularly relates to rooting water for tobacco transplantation and a tobacco transplantation method based on the rooting water.
Background
The root of an annual or limited perennial herb of the genus Nicotiana of the family Solanaceae is slightly lignified. The inflorescence grows at the top, is conical and has a plurality of flowers; the shape of the capsule is egg-shaped or rectangular, and the length is approximately equal to the length of the persistent calyx. Blossoming and bearing fruit in summer and autumn. Tobacco prefers warm and sunny environment and fertile and loose soil, and is drought-resistant, cold-resistant and heat-resistant. Tobacco is an important economic crop, brings great economic benefits, becomes a main financial source of tobacco primary producing areas, and plays a role of an economic support. For farmers, planting tobacco is one of the main sources of income; tobacco revenue is an important economic source for countries and some regions. Besides important economic value, the tobacco also has various uses such as industrial value, medicinal value and the like.
At present, seedling transplantation is the most extensive method for tobacco cultivation, and is often influenced by plant diseases and insect pests in the processes of tobacco seedling transplantation and later growth. When the seedlings are just transplanted, the root systems and the surrounding soil cannot be fully fit, and the growth of the root systems is easily hindered, so that the deep pricking of the root systems is not facilitated, and the water is absorbed to cause dead seedlings; root rot can cause root rot in the growth process, influence water absorption to enable the whole plant to become yellow and withered, and finally cause the plant to die; on the other hand, the harm of underground pests such as cutworms and the like causes seedling shortage and ridge breaking and seriously influences the normal growth of tobacco plants. The root fixing water is water for seedling formation and root field planting and rooting of the root system after tobacco seedling transplantation, and the loss of the root fixing water can cause difficult field planting of the root system in soil, and the root fixing water can not absorb water to cause dead seedlings. But the rampant harm and root rot of the underground pests are getting worse in recent years.
The formula design of the root fixing water in the prior art is not reasonable enough, and a multifunctional root fixing water which is not only beneficial to transplanting and rooting of tobacco seedlings, but also beneficial to preventing and controlling soil insects and root rot and a tobacco transplanting method based on the root fixing water are lacked in production.

S3, deep ploughing to achieve a ploughing depth of 25cm, balancing, removing field weeds and tobacco plant residues in a combined manner, and reducing the initial infection source of diseases and insect pests, wherein the deep ploughing has no large upturned soil in the deep layer; digging side ditches and waist ditches during soil preparation, wherein the side ditches are deeper than the waist ditches by more than 10cm, and the waist ditches are deeper than the sub ditches by more than 10cm, so that the furrow is required to be straight and convenient for drainage and irrigation; the uniform direction of the moisture is determined for managing the moisture, which is beneficial to the ventilation and lighting of the tobacco field, the width of the moisture is 40-45cm, the height of the moisture is 20-25cm, and the moisture is managed by pulling the wires according to the row spacing of 120 multiplied by 50-55 cm.
And S4, fixing the tobacco seedlings, watering the tobacco seedlings with enough root fixing water, filling the tobacco seedlings with fresh yellow soil, and compacting the tobacco seedlings. In the water-requiring period, proper irrigation is carried out for 1-2 times. The transplanting density of tobacco seedlings per mu of land is not too dense, about 1200 tobacco seedlings are suitable, and 300ml of roots are irrigated with root fixing water per tobacco seedling.
S5, in the process of watering and applying root fixing water, the root fixing water can be guaranteed to be capable of watering soil thoroughly and not causing any harm to tobacco leaves. Therefore, a cellar type root water application device can be applied. The cavity formed by the inner conical surface and the outer conical surface of the device not only can ensure that the root fixing water can be uniformly sprayed to the periphery of the wall of the well cellar, but also can uniformly wash the soil around the root fixing water down to be fully combined with the root of the tobacco seedling, and can also prevent the root fixing water from generating phytotoxicity.
The method provided in this example was used as a test example, and a test conducted by a method of applying root fixing water containing only Bacillus licheniformis-Bacillus methylotrophicus aqueous solution was used as a control example, and tobacco seedlings were planted at the same time, wherein the test site was Conyza sativa 99, a Conyza domestica prefecture of Liangzhou, Sichuan. After the tobacco seedlings are mature, calculating the disease incidence rate of tobacco, the damaged plant rate caused by underground pests, the yield and the upper equal tobacco ratio.
The tobacco seedling quality and yield test data are shown in table 5 below:
TABLE 5
Percentage of damaged plants% The incidence of disease% Yield kg/mu The first-class smoke proportion%
Test examples 7.12 15.58 182.36 30
Comparative example 13.64 20.74 172.93 33
As can be seen from the results in the above table, the advantages of the method of the present embodiment can be seen by comparing with the comparative example. By investigating the pest rate of the underground pests, the disease incidence of the test example is lower than that of the control example and is 7.12 percent; in the disease occurrence situation, the disease incidence of the test example is 15.58 percent and is reduced by 5.16 percent compared with the 20.74 percent of the control group; as can be seen by comparing the acre yield and the first-class tobacco ratio of the test example and the control example, although the first-class tobacco ratio in the test example is slightly lower than that of the control group, the acre yield is improved by nearly 10 percent compared with that of the control group, and the root strengthening effect of the root fixing water can be indirectly shown. Through data comparison, the method is beneficial to reducing the occurrence of diseases, improving the yield of tobacco leaves and increasing economic benefits.
The preferred embodiments of the invention disclosed above are intended to be illustrative only. The preferred embodiments are not intended to be exhaustive or to limit the invention to the precise embodiments disclosed. Obviously, many modifications and variations are possible in light of the above teaching.
