Secret books on the cultivation and management of high yield of rice in summer! If you master five points, you can have a high yield.

Summer is a critical period for growing rice, and if this time is not grasped, it may lead to a reduction in yield, so what are the secrets of high-yield cultivation and management of rice in summer?

First, ploughing in the early and middle period to kill stubble

When sowing summer millet with stubble, the general soil is hardened and the ventilation is poor, which is very disadvantageous to the growth of seedlings. We should plough and destroy stubble as soon as possible, break the hardening, loosen the soil, eliminate weeds and improve the nutritional environment of summer millet. The first mid-tillage is generally combined with inter-seedling, so as to achieve the combination of weeding, stubble and surrounding seedlings. Deep ploughing once before jointing, breaking shallow roots to increase new roots, promoting root growth, forming a strong root system, and enhancing the ability to absorb water and fertilizer.

Second, the early crackdown on the seedlings

In the land with good water and fertilizer conditions, high yield and dangerous lodging in the later stage, the seedlings are pressed green when the seedlings grow 2-3 leaves, that is, they are pressed or pressed with their feet when the leaves of the seedlings droop in the afternoon on a sunny day. If there is more moisture in the topsoil, it should not be pressed. Pressing green can effectively control the steep growth of aboveground parts, thicken the stem base of grain seedlings, promote seedlings to take root early and quickly, improve the ability of drought resistance and water and fertilizer absorption, prevent lodging, and play a role in squatting seedlings.

Third, the seedlings are fixed in the morning

Summer valley from emergence to jointing, the time is short, the growth is fast, and at this time has entered the rainy season, in case of continuous rain, whisker roots grow very fast, often bring difficulties to seedlings, not only labor-consuming, but also hurt seedlings, affecting the growth of seedlings. When the summer valley clover is of one heart, it is the right time for the seedlings to pull out the sick and weak seedlings and weeds. The yield of suitable time seedlings is generally 10-15% higher than that of night seedlings. When the five leaves are of one heart, it is the suitable period for fixing seedlings, leaving seedlings evenly and keeping strong seedlings, with 50-60 thousand seedlings per mu.

Fourth, topdressing and watering in the morning

Generally speaking, 10 kg urea per mu can be applied before jointing in summer valley, which can be combined with watering. When the soil moisture is good, it can be applied in series directly. The summer valley should generally be irrigated with enough soil moisture, and those who do not water the bottom moisture should be watered in time, which is conducive to the early development of seedlings. After jointing, vegetative growth and reproductive growth go hand in hand, and more water is needed. Millet is most afraid of "fetal drought" and "neck drought". If the soil moisture is not good, you must pour enough water. Keep the ground moist and promote millet to have big ears and good millet filling. Avoid watering in windy weather to prevent lodging.

5. Early pest control

The main pests in summer valley are drill worm and armyworm. The suitable time for the control of summer valley drillworm is to control with poisonous soil when two leaves are of one mind. The method is to use 50% 1605 emulsion 100-200 ml, first dilute it with a small amount of water, then spray it on 40 kg fine dry soil with a sprayer, and stir evenly. With 20 kg poisonous soil per mu, sprinkle along the seedling ridge on the heart leaf, leaf sheath and ground of the seedling. After booting stage, we should also pay attention to the control of armyworm, which can be sprayed with dimethoate powder.

To sum up, the secret of high yield is to catch five mornings, as long as you catch these, you can increase your yield and make your rice grow better.
