Embodiment approach 1
[0021] 1. Preparation before broadcasting
[0022] High-yield and high-quality varieties that can grow well in sandy deserts and have strong stress resistance are selected. The characteristics of the varieties are sub-limited types, the main stem has pods, and the growth period from emergence to maturity is 115 days.
[0023] 2. Film-on-demand
[0024] In the sandy desert, the snow melts faster in spring and the ground temperature rises faster. The sowing date can be 5-10 days earlier than that of the loam soil. The earlier the better under the premise of ensuring the temperature, the sowing can start on April 5. The film on-demand machine is used for sowing, and the operations of drip irrigation belt, film covering, drilling, hole planting, and soil covering are completed at one time. The drip irrigation belt adopts the single-wing labyrinth drip irrigation belt produced by Xinjiang Tianye. The sowing mode is three membranes, six tubes and twelve rows of soybeans, wide and ...
Embodiment approach 2
[0030] The difference from Embodiment 1 is that the water is poured every 7 days during the flowering period, and the irrigation quota is 45.0mm; Water drips once every 12 days, and the irrigation quota is 30mm.
Embodiment approach 3
[0032] The difference from Embodiment 1 is that the water is poured every 6 days during the flowering period, and the irrigation quota is 41.5mm; Water is dripped once a day, and the irrigation quota is 22.5mm.
