Embodiment

[0029] The drip irrigation method for planting cotton in severe saline-alkali land of the present invention, the technical key point that this method adopts is to sow on-demand after pipe laying and film dripping before cotton sowing, and adopts drip irrigation under the film during the cotton growth period, and the specific operation is carried out according to the following steps:

[0030] Pre-broadcast preparation:

[0031] After the cotton is harvested in that year, the cotton stalks can be kept to reduce the wind speed and achieve the purpose of maintaining soil moisture. At the beginning of March in the next spring, first use the cotton stalk machine to completely crush the cotton stalks, and wait for the soil to freeze in mid-March. When the thawing of the soil layer reaches 35cm, plow and prepare the land, and the plowing depth is 25-30cm;

[0032] Capillary layout:

[0033] On the treated land, the film laying machine is used to lay the film and the drip irrigation b...

Abstract

The invention relates to a drip irrigation method for planting cotton in severe saline-alkali land. The method adopts the steps of pre-sowing preparation, capillary laying, drip irrigation, and salt control during growth period. This method does not carry out traditional submerged irrigation in autumn and winter after cotton is harvested. Before cotton is sown, pipes are laid and covered with film to drip water, and drip irrigation under film is used during the cotton growth period. It is aimed at the current situation of decreasing agricultural water consumption. A new water-saving and salt-controlling technology developed is an important supplement to the traditional method of flooding salt irrigation with large water. It has the advantages of less water consumption, good salt washing effect, and high crop emergence rate. The severely salinized areas have great potential for popularization and application.

Description

technical field [0001] The invention relates to a drip irrigation method for planting cotton in severe saline-alkali land, which can achieve the goals of saving water and controlling salt, preserving seedlings and increasing production. Background technique: [0002] Due to the arid climate in Xinjiang and the soil parent material that is prone to salt accumulation, soil secondary salinization is common. In order to ensure the normal growth of crops, the irrigation mode of winter irrigation or spring irrigation is generally formed in the irrigation area. Whether it is traditional surface irrigation or micro-irrigation that has been widely promoted at present, in addition to the normal irrigation during the crop growth period, after the crops are harvested, they must be irrigated with salt-washed alkaline water (winter irrigation) in autumn and winter or irrigated with ice-melting water to preserve moisture before planting in spring. (spring irrigation). These two kinds of w...
