First of all, the Dutch bean is mainly planted in a simple solar greenhouse in winter(greenhouse supplies pots), seedlings in early October, planting in early November, and harvesting from late December to mid-February. Seedlings are selected after seeding, and 2-4 seeds per hole, the hole distance is 10 cm, and the calendar seedling age is about 30 days(11cm plastic grow pots). When the seedlings are 4-6 pieces of true leaves, the strong stems with thick stems and short and no lodging are selected.
Hormone treatment flowering period with 30 × 10-6 anti-falling leaf spray to prevent falling flowers and pods. Same field management in the spring(black plastic plant pots). Continuous cropping obstacles have become an important issue in the current vegetable production. Planting crops are relatively simple, and it is difficult to avoid heavy obstacles and affect the quality and yield of crops(110mm plastic grow pots). Therefore, it is necessary to rotate to achieve high quality and high yield of crops.(heavy duty 3 gal nursery plant containers)
Rotation is a plan to plant different types of crops and different types of multiple crops on the same ground(wholesale greenhouse pots). So what are the key points and principles to pay attention to in vegetable rotation? Let's take a look at it. The same family or the same kind of vegetables can not be continuous, such vegetables will generally have the same pests and diseases, the required nutrients are similar, such as the common weeds(propagation tray), melons and onions and garlic can not be continuous with each other.
Temperature management When the temperature exceeds 25 °C during the day(flat plastic tray), the air is released in a timely manner, and the temperature is not lower than 10 °C at night. The temperature during the pod-forming period can be lower, 15-18 ° C during the day and 12-16 ° C during the night. Rotating vegetables with different soil nutrients and different root depths: According to the degree of soil nutrients absorbed by vegetables and the depth of roots(plug trays), the soil nutrients can be fully utilized.
(heavy duty 3 gal nursery plant containers)Other management of vegetables with different root distribution or different shades of vegetables can be used for continuous cropping(seed starter trays). Its role is mainly to balance the nutrients of different soil layers. When different kinds of secretions have mutual promotion effects, onion and garlic can secrete a bactericidal substance, so they can be used as a rotation vegetable to effectively accumulate soil-borne pathogens(gallon plant pot). Especially the rotation is the problem to be solved.
In greenhouse greenhouses, in the process of conversion to organic agriculture(plastic grow pots), the rotation of the same vegetables: the same pests and diseases occur in the same vegetables, and the rotation of different vegetables can make the bacteria lose the host or change the living environment, so as to reduce or eliminate pests and diseases(cell trays). The common deep root vegetables are eggplant melons, and the shallow root vegetables are leafy vegetables.
Pay attention to the effects of various vegetables on soil pH and soil fertility: such as planting cabbage, potato, etc.(square nursery pots), will increase soil acidity, while planting corn, pumpkin, etc., will reduce soil acidity. The onion, which is sensitive to acidity, can be used as a post-production of corn and pumpkin, and a higher yield can be obtained(gallon nursery pots). Some legumes, grasses or crops can be arranged to increase soil structure and increase soil fertility.(heavy duty 3 gal nursery plant containers)
