What are the breeding methods of scutellaria baicalensis? Direct seeding and transplanting have their own advantages and disadvantages

There are two main culture methods of Scutellaria baicalensis Georgi: direct sowing and transplanting. Direct seeding method: more, generally sowing in spring, using the direct seeding method, the root system of Scutellaria baicalensis Georgi is straight and less forked, the appearance and quality of the commodity will be better, and it will be labor-free. Transplanting method: it is often used in the case of expensive seeds or lack of water in dry land, and it is difficult for direct seeding to emerge and protect seedlings, because transplanting is more labor-intensive, and the transplanting main root of Scutellaria baicalensis Georgi has more short root forks, so it will affect the appearance and quality of the commodity.

Culture methods of Scutellaria baicalensis Georgi

1. Live broadcast method

The root system of Scutellaria baicalensis seed direct seeding is straight, the root bifurcation is less, the appearance quality of the product is better, and it saves labor. Generally, the live broadcast of Scutellaria baicalensis Georgi is carried out in spring, when the low temperature of underground 5cm is stable at 12-15 ℃, and in the north around the first and middle of April.

2. Transplanting method

Seedling transplanting can save planting to a certain extent, prolong the growth time of Scutellaria baicalensis, in order to ensure the whole seedling, but it is relatively labor-intensive, and the main root of Scutellaria baicalensis Georgi is shorter, the root bifurcation is more, and the appearance quality of the commodity will be worse. This method is generally used when seeds are expensive or dry land is short of water, so it is difficult for direct seeding to emerge and protect seedlings.

Planting technique of Scutellaria baicalensis Georgi

1. The seedlings are fixed

After the seeds of Scutellaria baicalensis Georgi were direct seeded, when the seedlings reached the 4cm height, the seedlings were interplanted in time, and the seedlings which were too dense and thin were removed, and the seedlings were determined according to the plant distance 10cm.

2. Ploughing and weeding

After the seedlings of Scutellaria baicalensis Georgi were unearthed, the work of loosening soil and weeding should be carried out in time, and the soil should be properly cultivated around the seedlings to ensure that the soil was loose and weed-free and promote the growth of seedlings.

3. Fertilizing and watering

When the seedlings of Scutellaria baicalensis Georgi reached 10-15cm, one topdressing was carried out and human and animal manure water was sprinkled according to the ratio of 1500-2000kg/ mu. From the end of June to the beginning of July, 20kg superphosphate and 5kg urea were applied per mu, and ditches were spread between rows, and then covered with soil before watering. After the next year's harvest, after the plant withered, trench was opened between the rows, 2000kg rotten barnyard manure, 20kg superphosphate, 5kg urea, 150kg plant ash were sprinkled per mu, and then covered with soil. Scutellaria baicalensis Georgi is more resistant to drought, but afraid of waterlogging, so it should be drained in time during the rainy season to ensure that there is no stagnant water in the field to avoid rotting roots of Scutellaria baicalensis baicalensis. After some serious drought or topdressing, a little water can be poured appropriately.

4. Remove the buds

Before the inflorescence is pulled out, the pedicel should be cut off to reduce nutrient consumption, promote root growth and increase yield.

5. Disease and pest control

Scutellaria baicalensis is easy to suffer from leaf blight. In the process of planting, regularly clean the countryside and spray Bordeaux solution with 1 and 200% or 520% carbendazim 1000 times to prevent and cure it. If Scutellaria baicalensis Georgi suffers from root rot, pay attention to drainage, pull out and burn the diseased plants as soon as possible, and then disinfect them with lime.
