Description
Technical Field
The invention relates to the technical field related to strawberry seedling culture, in particular to a method for concentrated cutting of strawberry substrate seedlings under simple facility conditions.
Background
The perennial herb fruit tree of strawberry (Fragaria anassaduch) has fresh, tender and succulent fruits, sweet and sour flavor, unique flavor and rich nutrition, and compared with other fruit trees, the fruit tree has short cultivation period, is suitable for facility cultivation and has higher economic benefit. The Hongyan is one of the main varieties of strawberry cultivation in China at present, but the anthracnose infection rate is high, the problems of frequent anthracnose of the strawberries and potential anthracnose infection of the strawberries cannot be solved by the current common field seedling raising mode, and the situation that the Hongyan strawberry seedling raising is difficult is caused.
The matrix seedling raising mode can thoroughly block the occurrence and the propagation of anthracnose, but the prior strawberry matrix seedling raising has the main technical problems of low seedling yield per unit area, poor matrix seedling quality, overhigh seedling raising cost and the like, and the problems are related to the low cuttage survival rate of the matrix seedlings to a certain extent.
The cutting is an important process for raising the strawberry seedlings by using the matrix. The cutting operation process is that stolon seedling of strawberry is taken down from the mother plant and then transplanted into a container filled with matrix for cultivation. Strawberry stolons are grown into seedlings in sequence in different sections, if the time span before and after batch cuttage is large, the time from the 1 st-section seedling growth to the 3 rd-section seedling growth generally needs 21-30 days, and if the seedling growth amount is large, multiple times of tissue labor are needed for carrying out the cuttage process, so that time and labor are wasted.
Disclosure of Invention
Aiming at the technical problems of low cuttage survival rate, low seedling yield in unit area, poor quality of matrix seedlings, labor waste in operation and overhigh seedling raising cost in the prior art, the invention provides the method for the concentrated cuttage of the strawberry matrix seedlings under the condition of simple facilities, the steps are simple and convenient, the operability is strong, and the cuttage survival rate of the strawberry matrix seedlings can be improved.
In order to achieve the purpose, the technical scheme of the invention is as follows:
a method for concentrated cutting of strawberry substrate seedlings under simple facility conditions comprises the following steps:
s1) under the air temperature condition of 25-30 ℃, intensively shearing the strawberry stolons in uniform time to obtain stolon seedlings;
s2) grading the stolon seedlings obtained in the step S1, wherein the first-stage seedlings directly enter the next step, and the second-stage seedlings enter the next step after being subjected to root system activation treatment by a root system activation solution;
s3) respectively cutting the first-stage seedlings obtained in the step S2 and the second-stage seedlings subjected to root system activation treatment into hole trays filled with wet seedling raising substrates to obtain strawberry cutting seedlings;
s4) placing the strawberry cutting seedlings obtained in the S3 in a simple facility covered with a sunshade net for cultivation.
Wherein the temperature of the concentrated cutting of the seedlings in S1) is required to be below 30 ℃, and the operation is most suitable when the temperature is 25-28 ℃. As the strawberries are fond of warm and cool climate and are very sensitive to temperature reaction, the growth temperature of the plants is 5-30 ℃, the growth of the plants is inhibited when the temperature is higher than 30 ℃, and the temperature is suitable for 15-25 ℃. The growth suitable temperature of the strawberry root system is 15-23 ℃, the optimum temperature is 17-18 ℃, the growth of the root system begins to be poor when the temperature is higher than 28 ℃, and the accelerated aging of the root system is higher than 30 ℃. In order to improve the cuttage survival rate, the temperature is 28 ℃ when concentrated cuttage is carried out, and the temperature is at least above 25 ℃ during the day when the stolons meet the concentrated cuttage requirement, so that the temperature is required to be below 30 ℃ and is most suitable to be 25-28 ℃ when the seedlings are cut off in a concentrated manner. Taking the northern area of Zhejiang as an example, such air temperature conditions usually occur during the plum rain period between 6 months and 10 days to 30 days.
Preferably, the strawberry stolons in S1 are strawberry stolons having at least 3 or more different nodal position seedlings; it is noted that about 21-30 days are needed for one stolon to form 3 nodal seedlings from the period of pumping; the invention is that the whole root is cut after 3 nodal positions of a stolon are formed, and then the seedlings are respectively cut off for grading and cuttage.
Preferably, the classification in S2 is performed depending on the root activity and/or seedling age of the stolon seedling.
Preferably, the first-class seedlings are stolon seedlings with the seedling age of within 15-20 days or the root activity of the first-class seedlings is more than or equal to 0.5 mg/g.h calculated according to the reduction strength of tetrazole; the secondary seedlings are stolon seedlings with the seedling age of more than 20 days and the root activity of less than 0.5 mg/g.h calculated according to the reduction strength of tetrazole.
The reason for grading according to the standard is that the root system does not grow late after the strawberry stolon seedlings are cut is a main factor causing low cutting survival rate, and the root system activity is related to the root system activity of the strawberry stolon seedlings, the root system activity is more than 0.5 mg/g.h (tetrazole reduction strength), the root system activity is strong, the root system grows fast after cutting, more new roots occur, and the survival rate is high; the root activity is less than 0.5 mg/g.h (tetrazole reduction strength), the root system is easy to age, the root system grows slowly after cuttage, new roots are not easy to grow, and the cuttage survival rate is low. In addition, the root activity is also related to the seedling age of the strawberry stolon seedlings, and the longer the seedling age is, the serious aging degree of the root system is and the root activity is low. The seedling age of the strawberry stolon seedlings is within 15-20 days, and the strawberry stolon seedlings are white in root system and strong in activity; when the seedling ages for more than 20 days, the root system begins to brown and age, and the activity is weakened. Therefore, the grading is carried out by taking the root activity of 0.5 mg/g.h (tetrazole reduction strength) as a boundary according to the root activity difference of the strawberry stolon seedlings, or the grading is carried out by taking the seedling age of 15-20 days as a boundary according to the seedling age of the strawberry stolon seedlings.
Preferably, the root system activating solution is an aqueous solution of naphthylacetic acid or a mixture of sodium naphthylacetate and water-soluble calcium.
Preferably, the concentration of the naphthylacetic acid or the sodium naphthylacetate in the aqueous solution is 5-10 mg/L, and the concentration of the water-soluble calcium is 10-40 mg/L.
Preferably, the root system activation treatment is to place the roots of the second-stage seedlings in the root system activation solution for soaking for 1-2 hours, and it is to be explained that the seedlings positioned on different nodes of the stolons can form adventitious roots, and just can be cut because of the formation of the adventitious roots, as described above, the seedlings are cut after 3 nodes of one stolon are formed, and the formation of the 3 nodes of the seedlings requires 21-30 days, that is, when the seedlings of the third node are formed, the seedling age of the first-node seedlings is close to or exceeds 20 days, the adventitious roots are browned, the activity is reduced, and the treatment is needed, while the seedlings of the second-and third-node seedlings are short, the activity of the adventitious root system is good, and the cutting can be performed without the treatment.
That is, after the step of S2, the strawberry stolon seedlings with root activity less than 0.5 mg/g.h (tetrazole reduction strength) and seedling age over 20 days need to be treated by using a rooting activator, so that the root system of the strawberry stolon seedlings is promoted to elongate and thicken, new roots are induced, and the survival of the cutting is promoted.
Preferably, the seedling culture substrate in S3 is a mixture of peat and perlite in a volume ratio of 1: 1-3: 1.
Preferably, the shading rate of the sunshade net in S4 is 70-80%.
According to the technical scheme, stolon seedlings with different root system activities and seedling ages are subjected to graded cuttage and differentiation treatment, the cuttage survival rate is greatly improved to over 90 percent, and compared with the conventional cuttage survival rate of 75 percent on average, the cuttage survival rate is obviously improved, and the unit area seedling yield is favorably improved.
Due to the adoption of the technical scheme, the invention has the remarkable technical effects that:
1. the strawberry stolon seedlings are subjected to concentrated cuttage, so that the operation efficiency is higher, and the labor cost is saved;
2. the stolon seedlings are subjected to graded cuttage, differentiation treatment and graded management, so that the cuttage survival rate is greatly improved, and the management and control of the quality of the strawberry matrix seedlings are facilitated;
3. the strawberry substrate seedling centralized cuttage is carried out in a simple facility, the substrate seedling raising cost can be reduced, and the operability is strong.
