Sorrel Planting and Cultivation Techniques and Common Disease Control Methods

Abstract Time: spring and autumn when the temperature does not exceed 35 degrees. Site selection: relatively fertile land is most suitable, and certain irrigation conditions are needed. Land preparation: level the land, build the field bed ridges well, and control the spacing and number of rows. Sowing: soak the seeds for one day, and place 6 to 7 seeds in each hole. Fertilizing: before planting, use diammonium phosphate as base fertilizer and spread it evenly in the field. Density: determined according to the germination rate; usually the sowing rate is about 15 grams per mu, and the depth is about 2-3 cm.

Sorrel is distributed widely, and is found in eastern, southern, and northern China. It is a highly medicinal plant with detoxifying and laxative effects, and can also be used as a vegetable or feed. If planting sorrel, we usually need to pay attention to many things; temperature control and humidity control are both very important. Let us learn about sorrel planting together below.

Sorrel Planting and Cultivation Techniques

1. Selection of planting plot

A fertile plot of land needs to be selected. Fertile soil is crucial for planting plants, and certain irrigation conditions are also needed, so that when drought occurs it can be irrigated at any time, and when there is too much water it can be drained. Remember not to plant in poor land, otherwise growth will be affected.

2. Apply sufficient base fertilizer and prepare the land well

1. Each mu of land needs 3000 to 4000 jin of fertilizer, using 20 kg of diammonium phosphate as base fertilizer, spread evenly in the field, and then carry out later treatment.

2. Level the land, build the field bed ridges well, control the spacing, and design the number of rows well. This can be done with a tractor or by hand.

3. Sowing

1. Sowing season: both spring and autumn can be used for sowing. If the ground temperature exceeds 35 degrees, it is not suitable for sowing.

2. Sowing amount: how much to sow depends on the germination rate at the time, which determines the density of seedlings. Usually the sowing amount for one mu of field is about 15 grams.

3. Sowing depth: the living seed is not very large and is a dicotyledonous plant. The plant's characteristics basically mean the emergence rate is relatively low. Therefore, the sowing depth must be controlled well, generally about 2 to 3 cm, and it must not be too deep. Plant it in the same way as the cultivation method for sowing vegetables.

4. Sowing method: before sowing, the seeds need to be soaked in clean water for one day and one night, then taken out and dried, and then sown in holes on a good weather day, placing 6 to 7 seeds in each hole, which makes it easier for seedlings to emerge.

5. Raising seedlings and transplanting: the number of seedlings to raise needs to be determined according to the active area, and the method of raising seedlings is usually the same as that for ordinary vegetables. Nutrient pots can be used for raising seedlings, or seedlings can be raised directly in the ground, but it should be noted that if seedlings with fewer leaves are selected for transplanting, the survival rate will be low, so seedlings with more leaves should be selected; generally 6 to 7 leaves is very suitable.

4. Field management

1. Ensure full stands: the soil nutrients must be good, and a suitable temperature should be chosen for seedling emergence. After about one month, 4 to 6 leaves will grow. At this time, attention must be paid to protecting the seedlings. Protecting seedlings requires water, because during this period they are not resistant to drought, so irrigate promptly according to the situation. The final thinning stage is usually when they grow to six leaves, and the plant spacing is generally about 20 cm, with 3 to 4 plants placed in one hole.

2. Cultivating and weeding to ensure full stands: about one month after final thinning, sorrel usually grows, and during this period some weeds will grow in the field and coexist with the sorrel, but the weeds usually grow faster, causing malnutrition in the sorrel seedlings, so the weeds must be removed to give the seedlings a good environment.

Common Disease Control Methods for Sorrel

After sorrel emerges, bird damage needs to be prevented and controlled. At this time, some props can also be made, such as tying straw into human shapes and placing them in the field to prevent birds from coming. From July to September, pests need to be prevented and controlled at this time, usually mainly cabbage caterpillars and cutworms. When the larvae pupate, use 90% trichlorfon crystals, or 80% dichlorvos, to eliminate these larvae as a control method.

For the first three days of sorrel planting, the soil needs to be kept moist. At the same time, when selecting seeds, some dry and poor seeds need to be removed, so as to improve the survival rate. Throughout the seedling stage, the most important thing to pay attention to is moisture. If everyone controls it well, they will grow good sorrel.
