Vegetables are a variety of cross-facility plants that are well nourished, tasted and popular with a wide range of consumers. The following is an introduction to gardening techniques and fertilization methods:
I. Technology for the production of pieces
Soil requirements: vegetables should normally grow at a depth of 30 cm or more, with deep, well-drived, well-ventilated, fertile and corrosive soils more suitable. Soil ph should be in the range of 6. 0-7. 5, and peracid alkalis are not conducive to vegetable growth。
The planting time is two to three times a year, usually in the spring, summer and autumn seasons. In the north, it is appropriate to sow in the spring. In the south, due to high temperatures, several batches of seeding can be carried out using suitable climatic conditions throughout the year。
Seeding methods: vegetables can be grown either directly or by transplantation. Direct seeding is generally done at 30 cm line and 20-25 cm den, with 1-2 seeds per cave or ditch at depths of 1 - 1. 5 times the diameter of the seed. In turn, planting practices require the cultivation of seedlings and their transfer to established sites, with care to preserve the integrity of the plant and avoid damage。
Management point: the management of vegetable vegetables consists mainly of watering, weeding, pine earth and fertilization. Care should be taken to keep the soil wet in a timely manner, but also to avoid excessive moisture leading to the decay of the vegetable roots. Weeding and pine soil should be done in a timely manner in order to keep the soil soft and airy. Fertilizers can be applied in combination with organic and chemical fertilizers, which are controlled at about 15-20 kg per acre。
Ii. Fertilizing the vegetable
(b) base fats: the base fats of the florist are predominantly organic, including corroded compost, defecated livestock excreta, etc., which can be applied to the soil before the vegetable is planted. The application of base fertilizers is generally about 10-15 tons per acre, after which they need to be fully ploughed and mixed to ensure full distribution in the soil。
Fertilizers: veritables are mainly used as fertilizers, such as nitrogen, phosphorus, potassium and so forth
