Cassia seed is a dry and perfect seed of cassia obtusifolia or Cassia obtusifolia, an annual woody plant of leguminous plants. In fact, Cassia seed is the kind of pillow used by everyone to sleep. It is as cold as black beans. It has the functions of removing liver fire, expelling wind and dampness, benefiting kidney and clearing eyes. Many people who love flowers try to plant Cassia seed by themselves. Let's take a look at the cultivation techniques of Cassia seed.

Leveling planting land

It is advisable to choose the flat land or sunny sloping land with good drainage and irrigation standards, avoid continuous cropping 1 mu, apply 2000Kg of organic fertilizer, add 60Kg of phosphate fertilizer as base fertilizer, subsoil, trim and harrow, and make a flat border with a width of 1.3 meters.

plant

Generally, in the middle and late April, the seeds with round seeds and no insects are selected, soaked in warm water at 50℃ and added with new high-fat film for 24 hours, fished up and aired for a while, and then planted in rotary tillage holes with a row spacing of 60 cm and a ditch depth of 5-7 cm. After planting, the soil is filled with 3 cm, and then slightly pressed and watered; Buds can be sprouted in half a month, 1 mu of seeds is 2Kg, and the yield and quality of cassia seed can be obviously improved by covering with plastic film when planting.

cultivation techniques

Replenishing the seedlings, and gradually replenishing the seedlings when the height of the seedlings is 5cm. When the height of the seedlings is 15 cm, the fused intertillage weeding will bud according to the plant spacing of 30-40 cm; Weeding in intertillage should be done frequently after sprouting and before starting. After watering, soil degradation should be done in intertillage immediately, and attention should be paid to shallow hoeing between plants and deep hoeing in rows. When the seedling height is 40cm, the soil should be cultivated in the final intertillage 1 time, which can prevent the seedling from falling down.

Before the start of fertilization, the soil is fertilized 1-2 times, and the organic fertilizer 1 mu is applied 1000Kg, and the urea solution 15Kg is added, and it is watered immediately after application; The soil layer should always be moist during the whole growth period of irrigation and drainage, especially in the dry days of flowering. Pay attention to the drainage pipeline in rainy days; Pest prevention is based on flying control measures to spray drugs to eliminate diseases, and to spray new high-fat films to improve drug efficacy; Prepare in advance for winter cold resistance in late autumn and early winter, laying the foundation for bumper harvest and income generation.

Cassia seed is an annual coarse herb, so it is advisable to choose flat land or sunny slope with good irrigation and drainage standards to avoid repeated cropping. Deep-loosen land resources, fine-tune and harrow. Breeding with seeds, selecting seeds with round grains and no insects, soaking in warm water and adding new high-fat film can repel underground pests, protect against viral infection, improve the compressive strength of inhalation and improve the seed emergence rate; The yield and quality of cassia seed can be obviously improved by fishing and planting in the sun, spraying new high-fat film first and then covering it with plastic film.

Immediately replanting seedlings, budding, intertillage weeding, fertilizing, effective irrigation and drainage. And moderately spraying Caiguozhuangdiling to enhance the quality of bee pollen fertilization, promote the growth and development of fruit, without deformity, empty shell and chaff, with good uniformity, improved quality and continuous harvest; According to the countermeasures of flying control, spraying drugs to eliminate diseases, and spraying new high-fat film to improve drug efficacy, and preparing for winter cold resistance in late autumn and early winter, laying the foundation for good harvest and income generation.

Prevention and control of pests and diseases

In the early stage of gray spot disease, dark brown spots appeared on the leaves, and the middle color was slightly lighter. In the middle and late stage, dark gray moldy substances were formed on the spots. Before or before the onset of the disease, 40% bactericidal Dan 400 ~ 500 times solution sprayer was used to prevent, clean up the garden and solve the disabled body. The stems, leaves and pods of ring rot can be infected. The disease spot is nearly annular, and the wheel marks are not obvious. In the middle and late stage, the dense grayish black is a little smaller (the conidia of the pathogen), which is the same as the gray spot disease. The emergence of aphids is heavier. You can use a 2000-fold liquid sprayer with 40% dimethoate solvent, spraying 1 time every 7 ~10 days for several times.
