How to improve the effectiveness of summer vegetables

Before the seedlings, they must be irrigated. One of the main purposes of the seedlings is to promote the deep rooting of the roots. Therefore, when the seedlings are seedlings, it is necessary to ensure that the soil is dry and wet and the oxygen is sufficient. The watering of the seedlings before the watering is only enough to ensure that the lower layer has sufficient water and fertilizer supply to promote the deep rooting of the roots under the dry conditions and promote the plants to grow robustly.

Cultivated many times. On the one hand, the cultivator can cut off the capillary water in the soil, loosen and dry the top layer of soil, keep the bottom layer of water well, and ensure that the soil is wet and dry, which will help the root system to elongate in depth; on the other hand, as the cultivator cuts off part of the surface lateral roots, the plant suction is reduced. The nitrogen and nitrogen metabolism levels increase the accumulation of carbohydrates in the body, which is also conducive to plant growth and robustness.

Seedling time varies with climate, soil water and fertilizer conditions, as well as the type of vegetables, length of growth, and growth. Long time seedlings will inhibit the normal growth of plants, affect the differentiation of reproductive organs, easily lead to premature plant failure; too short, it will not achieve the desired results. For the vegetables with insufficient soil water and fertilizer, no seedlings growing vigorously and with short growth period, it is better to use the non-seedlings; for the vegetables with good water and fertilizer conditions, strong seedlings growing and long growing period, such as tomatoes, sweet peppers, etc., the best seedlings In order to enhance plant resistance, avoid premature aging and increase yield.
