How to preserve citrus fruit under autumn drought? Please give an introduction.
For autumn drought, citrus can be preserved by referring to the following methods:
1. Irrigation. Citrus orchards with irrigation conditions can be flood-irrigated in the afternoon, with the water depth slightly lower than the bed surface. Through overnight infiltration, drain the excess water from the orchard the next morning to avoid root damage from high midday heat. Citrus orchards without irrigation conditions can carry water to irrigate the tree basin, and before irrigation, first carry out mid-cultivation weeding in the tree basin. Carry 1~2 dan of water per tree, mix in 2% urea, and after the water is absorbed, cover with 3 cm of broken soil to avoid excessive evaporation and to prevent the soil surface from cracking and breaking the fibrous roots.
2. Tree basin mulching to lower temperature and retain moisture. Within the area directly under the canopy projection, spread 10 cm of rice straw, weeds, etc. If a layer of broken soil is also scattered on top, the effect is even better. Spraying Xinshouzhi film on the leaves and fruit surface can also reduce evaporation, prevent fruit drop and fruit cracking, improve fruit surface coloring and glossiness, reduce residual toxicity, and improve quality.
